Using the Nautica 4M System for School Busses


N/S Corporation has been leading the wash system industry for over 50 years with our innovative technologies and cutting edge patents. With over 70 patents filed by our founder, G. Thomas Ennis, we provide the reliability, quality, and standards our customers our looking for. All the effort we put into our systems makes our school bus wash systems especially cost-effective for school districts and learning institutions everywhere that have to maintain a frequently used fleet. Read on to learn how the Nautica wash system can make school bus maintenance easier!

What is The Nautica 4M?

The Nautica 4M Bus Wash Series is a fleet rollover wash system that comes in two versions: the Nautica 4M-12 and the Nautica 4M-14. Both systems are among the school bus wash systems that have the smallest outside dimensions, but can still be used to double wash busses in under four minutes!

Both systems have very similar dimensions for simple school bus maintenance, but the Nautica 4M-14 is slightly taller to allow for busses up to 14 feet tall to enter. The Nautica 4M-12 has a vehicle clearance height of 12 feet, and both systems offer a vehicle width clearance of 10 feet.

Atlanta APTA Expo


Every three years, the team at N/S Corporation takes a trip to attend the APTA Expo and showcase the new products and innovative technologies we’ve recently developed. This year the show took place in Atlanta. Next year the show will be in NS’s backyard, Anaheim. As a growing company, N/S Corporation wants to connect with other key players in the transit industry, develop long lasting relationships with industry design architects, and display our products. Learn more about our success at the APTA Expo here.



With a space over four times the size of our closest competitors, we can really take over the show. Our team has a depth of product to showcase that dwarfs other bus and train wash manufacturers’ displays, and allows end users to experience our product up close and personal without any additional marketing. Transit agencies and design engineers all have access to our newest systems! On display is over five decades of innovation. On display is the only true vertically integrated player in vehicle wash systems in the US.

What We Showcased


At this year’s APTA Expo, we highlighted our Smart Gate System — a pneumatically operated gate that opens and closes the inflow of air into a blower reducer’s impeller chamber. It reduces power consumption by up to 50% by eliminating the need to start and stop motors multiple times per hour. Since washing buses or other large vehicles can demand more starts and stops than a traditional system can handle, using our Smart Gate System minimizes motor damage to the wash system. Other benefits include:

  • Noise Reduction to Notably Lower Decibel Levels for a Safer Work Environment
  • Can Be Retrofitted for Any N/S Corporation Blower
  • Works Like a Small Compressor
  • Made of 75% Recycled Structural Aluminum
  • Has a Bolt On Design
  • Is Made in the USA!

Jerzy Boyz Teams Up with N/S Corporation

A San Pedro Car Wash Installation

When N/S teams up with local cash wash, we love showcasing the amazing results we’ve created with our car wash installations. Recently, our team completed the installation of a car wash for a valued customer, Jerzy Boyz Car Wash, in San Pedro CA. Read on to learn what a team up like this one created!

The Breakdown

Jerzy Boys purchased a wide selection of N/S equipment to create an amazing wash experience for all their customers. Their car wash installation included:

What to Expect

Jerzy Boyz

As you are greeted at the entrance of the car wash, the Excalibur conveyor will gently take up your wheel and introduce you to Jerzy Boyz magnificent tunnel.

The Excalibur Conveyor

The Excalibur Conveyor was designed to solve car wash operators’ dependence on compressed air to maintain chain tension, as well as issues with hard to reach multiple point lubrication spots and the countless hours replacing links and other components.

The Vortex Blast Arch

The Vortex Blast ArchThe Vortex Blast Arch

As the Excalibur glides your vehicle forward through this San Pedro car wash, you’ll find the Vortex Blast Arch. This is one of N/S Corporation’s prized new products. The Vortex Arch has six spinners with 4 jets each — two on each side and two on top, along with a 20 HP pump and the choice of a fun light package.

N/S firmly believes that applying a high pressure pump at the entrance of every tunnel properly prepares the car for polishing by blasting off road grime, dirt and in some cases salt film from coastal beach areas.

The Bubblizer

As your car progresses through this car wash, soap is dispensed from the Bubblizer. We’ve discovered over the past five years that dispensing bubbles is a cost effective and efficient way to spread chemicals over the exterior of a vehicle. It also enables car wash owners to create more top package options in a smaller space for more profits and a quick payback on the cost of a Bubblizer.

Lammscloth Pelts
Lammscloth Pelts

The robust Lammscloth Pelts are next up the car wash queue, and they offer superior polishing results along with a blast of color to liven up the tunnel. From the interior of your vehicle, you will see and hear, the benefits of Lammscloth massaging the exterior of your vehicle.

N/S offers red, black, blue, yellow, orange, lime, forest green and pink brushes for an easily customizable theme for your car wash. Jerzy Boys selected a combination of two Eco Brush stations for a total of eight brush elements, but NS offers various combinations of three, five, seven, and ten touch stations — each varying to fit your preferences and the length of the tunnel. See these various configurations here on our site.

Tire Gloss Applicator

Now right before the San Pedro car wash dryers kick in, chemical is gently massaged on the surface of your tires with NS Corporation’s world class Tire Gloss Applicator. This is a great top package enhancement because the TGA is the only tire shiner on the market that uses Lammscloth pads to apply chemical evenly, minimizing runoff and the amount of chemical applied.

Choose the Jerzy Boyz San Pedro Car Wash

There is no question that Jerzy Boyz has packed their tunnel with the best equipment money can buy. If you live in the San Pedro area, please stop by the Jerzy Boyz Car Wash for a first class washing experience!

If you own a car wash, we hope this display will tempt you to visit N/S Corporation to explore our equipment selection and purchase a reliable car was system from the leader – N/S!


N/S Corporation Installs Third Leak Test System for Train Manufacturers


Given the depth of knowledge and considerable experience in washing transit vehicles for decades, N/S Corporation is proud to announce that we have embarked on a new market segment: Leak Testing. We’re currently working with train manufacturers across the United States to ensure their trains are meeting the high quality control standards consumers expect. Read on to learn more about our innovative developments for the train testing industry.

Leak Testing Trains

Wet testing is a new and expanding vertical market. With train manufacturers now relying on N/S high pressure arches to test trains for leaks, we’re building customized designs to assist them.

The custom system pictured consists of a series of arches that blast manufactured rail cars with high pressure water. Over the course of the testing process, we bombard the trains from many angles to ensure that the seals on the railcars are strong.

At this location in Springfield MA, there are two 75 HP pumps in play, as well as a 40 HP pump. These pumps work in tandem to fuel 16 blast arches and 4 powerful undercarriage sprays, so no part of the train systems is untested.

A Trusted Partner

N/S Corporation is proud to partner with train manufacturers worldwide to assist in manufacturing quality control. If you’d like to work with us on any sort of custom leak testing system, reach out to our representatives today!

Our Technology

The Bubblizer

The Bubblizer technology revolutionizes how a cleaning system can tackle grime on vehicles. It uses a powerful stream of bubbles to deliver cleansing chemicals, unlike traditional foamers you find in other bus and car washes. The bubbles cover a large surface area, which allows you to use less water, chemicals, soap, and water during operation. Our Bubblizer ensures you use less chemicals and improves vehicle coverage.

The Eco-10

The ECO-10 is a ten-brush system that cleans and protects vehicles with increased efficiency. The ECO-10 system is the pinnacle of our ECO line of equipment. This brush system uses significantly less power than comparable brush systems, while still providing top quality wash services. The ECO-10 is an environmentally conscious bus, train, and car wash system that provides years of outstanding service for any eco-friendly car wash.

The Excalibur

The Excalibur Conveyor was designed to solve common problems including alleviating a bus or car wash’s need to rely on compressed air to maintain chain tension, accessing any hard-to-reach lubrication points, and reducing the amount of time needed to perform standard maintenance. It saves our partners time, money, and works hard to save the environment – one wash at a time.

Installing Foam Brushes

Bus, Train & Car Wash Foam Brush System

Are your fiber brushes at the end of their useful life? We’re here to help! At N/S Corporation, we specialize in delivering state of the art, easy-to-use products for your car wash facilities. We’ve developed a new product that will revolutionize the future of car wash technology. Read on to learn more about how to use them!

Eco Foam Brushes and Pelts

We are happy to introduce our new Eco Foam Brushes and Pelts, perfect for your bus, train, or car wash foam brush system. With these new, versatile products, you will be able to extend the life of your brushes in your facilities while improving results for your customers’ vehicles. The Eco Foam system is equipped with very thin strands that are designed to get into any crevice smoothly and easily. The material is closely sealed, so it will not absorb any water, dirt, or debris from wash to wash. Another feature we offer are the black pelts that were created for the bottom of the brush area. We made these bus and car wash foam brush system accessories black, so they won’t show any dirt from the harder cleaning areas of a vehicle.

The Perfect Fit!

If your fiber brushes are worn and have lost 40% of their brush volume, you may be ready to try something different. Switch to Eco Foam brushes and pelts for the ideal train, bus, and car wash foam brush system. When you’re ready to replace your fiber brushes, you can easily replace them with Eco Foam equipment. We’ve specially designed our brushes to ensure a direct fit into your wash system’s existing 15-1 gearbox, so there’s no need for you to replace them.

How to Install Your Car Wash Foam Brush System

To replace the top brush, rocker brush panels, and wrap brush, you simply need to drop the old brush down from its mounting and install the Eco Foam brush like you normally would. What’s even easier is that there is no driver or passenger side on the rocker brush panels and wrap brushes; these universal brushes will keep your installation as simple as possible.

It’s always easier to replace the entire brush, but if you need to replace an individual pelt, we can provide you with an all-in-one kit to use. N/S Corporation provides you with the correct hardware to install your replacement pelt and a configuration diagram to assist you with installation. Each pelt was made to fit into traditional fiber pelt bearings, so with just the use of a drill, you won’t skip a beat.

Designed for Your System

Our Eco Foam brushes and pelts are designed with you in mind. If you are in the market for a strong, durable, eco-friendly solution to your fiber brush issues, consider switching to N/S Corporation and our car wash products.

For more information about the Eco Foam brushes and pelts, please reach out to us today!

Bubblizer car wash

Market Misperceptions on the N/S Bubblizer

Bubblizer car wash

Car wash owners and operators have an obligation to offer the best possible services to all of their customers. With the popularity of modern car wash systems, there is a lot that goes into delivering outstanding service. From introducing innovative car wash equipment, like the N/S Bubblizer, to new car wash solutions, like automatic waxing and buffing application, car wash operators have to precisely balance everything to satisfy each customer.

The N/S Bubblizer is a revolutionary car wash package that utilizes a bubbling arch to create a dazzling light show, while efficiently applying wax or soap to a new or existing rollover system or tunnel. It also features multicolored lights to attract customers and provide a spectacular light show. Despite the simplicity of the system, there are a couple of misperceptions in the market that we would like to address.

Misperception #1: N/S Bubblizer is an inefficient way to deliver chemical.

There are some in the marketplace who perceive the N/S Bubblizer to be an inefficient way to deliver chemical — that is categorically false. This innovative system offers your modern car wash system a new and simple way to dispense chemicals instead of using foamers. The fact is, unlike foam that has to be circulated or pushed with friction material on vehicles, the N/S Bubblizer continually applies bubbles that run over the surface of your vehicle, ensuring thorough dispensing of the washing chemical and better coverage.

The marketplace misperceptions are largely based on misinformation on how the N/S Bubblizer works and dispenses chemicals. Rather than being a complex system, it’s designed with simplicity in mind, with its core purpose being to deliver and apply soap, wax, or glass treatments more effectively with the additional package of a dazzling light and bubble show.

Misperception #2: Car wash operators have no control over chemical usage.

Bubblizer light show

The N/S Bubblizer is a great addition to an already efficient car wash system. Despite what some people may think, this new chemical application solution—just like other modern wash solutions—allows operators to determine the exact amount of chemical to use. In short, it is easy for anyone in car wash operations to calibrate chemical usage down to the milliliter. For context, N/S Corporation used to sell a large number of Bubblizers to a chemical producer, so they had a vested interest in running up chemical usage.

The N/S Bubblizer comes with adjustable discharge and adjustable bubble density, allowing precise control over chemical usage. The system also allows more coverage and uses 50% less chemicals than other car wash solutions.

Benefits of the N/S Bubblizer

Minimal Chemical Usage

Considering that the Bubblizer technology makes use of bubbles to deliver chemicals over a more extensive area than regular foamers, it’s more effective and allows you to use less chemicals. That means minimal chemical usage, as low as 5 milliliters; this is dependent on chemical concentration levels.

Lower Water Consumption

Better bubble coverage with improved chemical efficiency means less water is used per vehicle, ensuring water consumption as low as ½ gallon per vehicle. Car wash owners and operators who integrate the Bubblizer technology into their new or existing wash systems are able to significantly reduce water usage.

Easier Operation and Functionality

Lava themed Bubblizer

  • The Bubblizer is much easier to rinse with full coverage when compared to foam applicators
  • The wax or soap delivery applicator is easier to adjust than foam curtains.
  • Fast and consistent solution discharge for a better and faster car wash.
  • It comes with mechanical valve switch for automatic system refill.
  • Easy bubble solution adjustability dependent on tunnel location (light or heavy bubble application).
  • Does not require compressed air, meaning it does not add load to the air compressor, unlike a foam curtain that will not work without compressed air.
  • The Bubblizer will not stop working if the air compressor goes down. This plays into the manual override feature of conveyors and how we focus on keeping the wash running even if you lose compressed air.
  • Dual and single air pump Bubblizer available for your car wash needs.

Easy Installation

The N/S Bubblizer can be installed on any type of car wash system you already have in place. Keep your business ahead by introducing the proven and quality car wash light show for an unforgettable experience for customers of all ages. The N/S Bubblizer requires no special requirements for installations. Dispense wax, soap ,and glass treatments with our efficient, dependable and cost-effective N/S Bubblizer, and expand your services and car wash revenue.

Car wash systems

At N/S Corporation, we strive to keep offering innovative and simple car wash systems and solutions that make a real difference in customer service. For more information about our themed Bubblizer applicator and other top quality car wash systems, contact us today at (877) NSWASH-1.

NS Flex Coupling Maintenance

NS Flex CouplingBackground: The NS Flex Coupling was designed specifically for transit and car wash machines by our owner/founder Thomas Ennis to withstand the rigors and abuse seen in drive through wash systems. The coupling is designed and tested to 12,000 pounds pulling force and flexibility up to 90 degrees under the most extreme conditions. Our Flex Coupling, unlike other brush coupling in our industry, does not require lubrication or continual adjustment. Under normal operation, it will last over ONE MILLION vehicle washes.

Following are a few tips to keep your Flex Coupling operating correctly, as well as some signs that a coupling should be replaced.

1. Correct brush contact pressure against the vehicle will minimize torsional load as well as minimize brush wear and possible vehicle damage.

2. Correct spacing between vehicles through the wash system will eliminate accidental pinching of the brush between two vehicles, which will cause excessive binding loads that will start shearing the mechanical rubber bond between the internal wire braided cable and metal yokes at each end.

3. Correct vehicle speed during initial brush contact should not exceed 1.5 miles per hour. Ramming the brushes will create a momentary stall situation, which can cause torsional shearing to internal mechanical bonds as well as  torsional stress loads to the internal stranded wire braided cable.

4. Replace a Flex Coupling if there are any visible cracks on the encapsulating rubber. Cracks are a sign of extreme flexing and/or dry-rot caused by age or harsh chemicals. Cracks in a coupling may not hinder its ability to continue performing normally, but they are an obvious sign of damage. Cracks will also allow for water ingress, which can cause internal corrosion that will eventually damage internal components that keep the brush from falling.

5. Replace a Flex Coupling if there is any noticeable deformity to the mounting bolt holes. Deformed/elongated mounting holes are a clear indication of prolonged torsional load damage. To check for mounting hole damage, grab the brush and rotate it side to side. If the brush rotates but the coupling does not, this would indicate damage to the Flex Coupling mounting holes or support hardware.

6. Replace a Flex Coupling if there is extreme separation of the mechanical rubber bond to the metal yoke at each end. To check for rubber to metal yoke separation, you can push the brush towards the wash bay entrance to see if the rubber separates from the metal yoke at the top or bottom of the coupling. If there is a gap larger than 1/8” and a flat screw driver with a 3/16 blade width can be pushed in between the rubber and the metal more than a 5/8” into the gap, the coupling should be replaced.  If the gap depth is less than 5/8 ” but a gap is present, the coupling should be routinely inspected and replaced if the gap increases.

Omega coupling maintenance

NS Corporation uses the Omega Coupling as a drive element for our Top Brush cleaning element, vacuum producer, and most of our pump systems. To ensure continual operation and eliminate unexpected downtime of your equipment, monthly inspections of the Omega drive coupling are essential.


When inspecting an Omega coupling, look for the following signs that indicate a potential failure or that replacement is required:

Look for any abnormal vibration of the equipment; this might be improper coupling alignment or damage to the Omega element.

Look for fatigue cracks on the element surface; if cracks are visible replace the coupling immediately.

Omega couplingLook for any missing or damaged hardware; missing hardware can cause vibration due to imbalance.

Look for discoloration of the elastomer element, which is a clear sign of material degradation and/or aging.

Look for damage or excessive corrosion of the element metal supports and shaft mounted hubs.

Proactive maintenance is key in eliminating down time. We recommend that the coupling element be replaced every 5 years, even if none of the above issues have been observed. Years of continual start and stop of the coupling can cause internal fatigue not visible by visual inspections. For any questions regarding this coupling or any other parts, contact NS Parts Sales at 1-800-782-1582.
