FREQUENTLY ASKED QUESTIONS

QUESTION:  WHAT IS CFM?

Answer:  CFM (Cubic Feet per Minute) is a measurement of the volume of air produced by an air compressor at a given pressure or PSI (Pound per Square Inch). The most common way to measure CFM is at 0 point head pressure, meaning measuring how much air it can produce without any air pressure applied to the compressor head. The higher the CFM rating that an air compressor has, the more powerful it will be.

QUESTION:  WHAT IS AN AIR COMPRESSOR?

Answer:  An air compressor is a machine that intakes surrounding air, then pressurizes and compresses that air for various purposes. Compressors can come in all different shapes, sizes, and capabilities and are powered by various methods. The compressors that we carry are intended for mobile pneumatic use and are typically powered by a 12-volt power source (such as a car battery). All of our Air Horn or Train horns will require an air tank and a compressor in order to work.

QUESTION:  WHAT IS DUTY CYCLE?

Answer:  A Duty Cycle is the percentage of time within a full cycle a compressor can run before resting. For the mobile compressors in our kits and onboard air systems, a full cycle is one hour. For example, a compressor with a 33% duty cycle will be able to run continuously for 33% of an hour (about 20 minutes) and need to rest for 67% (40 minutes) before it is ready to operate again. Most of the compressors that we carry measure duty cycle at 100 PSI, though the highest performing compressors measure duty cycle at 200 PSI. Since most of our systems run at 150 PSI, you do have to adjust for the higher pressure to get the most accurate idea of how long a compressor's duty cycle is when powering one of our kits. For example. the Viair 444C Air Compressor found in many of our popular kits has a 100% duty cycle at 100 PSI. At the 150 PSI that our systems run at, it would have more like a 75% duty cycle after you account for the extra 50 PSI. So, the 444C can run for about 45 minutes and only need to rest for 15 minutes. The most powerful compressors that have a 100% duty cycle at 200 PSI will actually run continuously for a full hour (or even a little longer) before they need to rest.

QUESTION:  DOES A COMPRESSOR THAT HAS 100% DUTY CYCLE MEAN THAT I CAN RUN THE COMPRESSOR ALL THE TIME? CAN I RUN MY COMPRESSOR 24 HOURS A DAY?

Answer:  No, even the most powerful compressors that we carry have to rest eventually. Keep in mind that one cycle for most mobile compressors is going to be one hour. Even then, that's typically at 100 PSI and an ambient temperature of 72°. A compressor's duty cycle should give you an idea of how long it can run compared to other compressors in its class. So a 100% duty cycle compressor can run much longer than a 33% compressor, but neither are going to run non-stop without rest.

QUESTION:  DOES IT MATTER WHERE I INSTALL MY COMPRESSORS ON MY VEHICLE?

Answer:  Where and how you install your compressor can absolutely make a difference in performance. If you are running a compressor that is vented and not sealed, you want to make sure to install it in a place that is as dry and free of dirt and debris. Since they're not fully sealed, moisture and dirt can be absorbed through the intake and get into internal components and damage the compressor. If you have a sealed compressor, you just want to make sure to install in an upright position so it can properly disperse heat.

QUESTION:  DOES A NEW COMPRESSOR NEED TO BE “BROKEN IN”?

Answer:  New compressors do not have to be “broken in”. After an install, power up the system to pressurize the system’s air tank to the pressure switch cut-off pressure and check for any leaks.

QUESTION:  WHY DOES THE ENGINE NEED TO BE RUNNING WHILE THE COMPRESSOR IS ON?

Answer:  We highly recommend that all of our kits are wired to ignition power so that your compressor will only power on when the vehicle is on. Your vehicle's electrical system only runs at 12 Volts while the vehicle isn't running, but when running, the alternator keeps it at 13.8 Volts (which is optimal for the compressors). Running the compressor without the vehicle on could cause an amperage spike that could fry your compressor or pressure switch. Even if it doesn't fry your kit, running the compressor with your vehicle off will drain your battery and cause unnecessary stress on the vehicle's electrical system.

QUESTION:  WHAT IS THE WARRANTY ON MY AIR COMPRESSOR?

Answer:  All Viair air compressors come with a One-Year Manufacturer’s Defect Warranty. All Oasis air compressors come with a One-Year Manufacturer's Defect Warranty. All Air Zenith air compressors come with a 2-Year Manufacturer's Defect Warranty.

QUESTION:  HOW CAN I TELL WHETHER THE COMPRESSOR IS SEALED OR NON-SEALED?

Answer:  Manufacturers will normally specify if a compressor is sealed against moisture and dust. We make sure to tell you if the compressor is sealed or not sealed on the product page for the compressor or air source unit, as well as in the instructions that come with the kit. In many cases, you can tell the difference by simply inspecting the compressor. Non-sealed compressors typically have air vents or holes in the compressor motor, while a sealed compressor would not. Sealed compressors also come with an air filter relocation kit, while non-sealed compressors would not. When in doubt, always feel free to contact us to confirm!

QUESTION:  IS IT IMPORTANT TO HAVE A SEALED AND MOISTURE RESISTANT COMPRESSOR?

Answer:  Depending on the mounting location of the compressor, this is extremely important. The preference of a sealed-type compressor is because compressors are likely to be exposed to outside elements, such as mounting to a chassis rail.

QUESTION:  I OPERATED MY COMPRESSOR FOR A LONG TIME AND NOW IT WON'T TURN BACK ON. DID I DAMAGE THE COMPRESSOR?

Answer:  This is unlikely. If the compressor is equipped with a thermal overload protector it will keep the motor from overheating to the point of permanent damage. Allow the compressor to cool for 30-45 minutes before you attempt to run the unit again.

QUESTION:  WHY DOES THE MOISTURE HAVE TO BE DRAINED FROM THE TANK?

Answer:  Draining the system of moisture prolongs the life of all the components, as well as keeping moisture out of the horns, which tends to cause a high pitch tone when blown. While our kits don't require much maintenance, the most important thing you can do to maximize the longevity of your onboard air system is to drain your tank on a regular basis. In fact, not draining your air tank could void any warranty on your system due to misuse or abuse.

QUESTION:  CAN I RUN MY SYSTEM AT 200 PSI?

Answer:  It depends, Some onboard air systems can handle 200 PSI and some can not. You want to check to make sure that both your compressor and tank are both rated for 200 PSI.

QUESTION:  HOW OFTEN DOES THE TANK NEED TO BE DRAINED?

Answer:  How often you drain your tank depends on how often the compressor runs. If you tend to use your onboard air frequently (daily), we recommend draining your tank about 3-4 times a month. If you are the typical every so often honker, you won't need to drain your system as much and can get away with draining your tank only 1-2 times a month.

QUESTION:  HOW DO I CHECK FOR LEAKS IN MY SYSTEM?

Answer:  Check for leaks by spraying a soap and water solution on your fitting connections. If there are bubbles present that grow in size, then there are leaks.

QUESTION:  CAN MY AIR SYSTEM BE USED FOR OTHER PNUEMATIC USES?

Answer:  Depending on which onboard air system that you decide to go with, your kit can be used for a variety of other pneumatic uses. Medium-duty or fast-fill compressors (found in our 232, 240 and 540 kits), are mainly designed for horns, but they can be used for tire inflation or as onboard air in an emergency. Any air system consisting of a constant-duty air compressor (like our 244,544,2485, and 5485 kits) can be used for any pneumatic use, such as air suspension, tire inflation, air tools and more!

QUESTION:  WHAT IS THE DIFFERENCE BETWEEN TRAIN HORNS AND AIR HORNS?

Answer:  The difference between Train Horns & Air Horns would be the pitch & volume they produce. Train Horns consist of at least 3 bells and produce a deeper tone as well as carrying a lot more volume. Air Horns produce a more high pitched tone and come in a variety of sounds.

QUESTION:  WHAT IS THE LOUDEST HORN YOU SELL?

Answer: The Nathan Airchime K-series horns will be the LOUDEST option on the market. These are actual locomotive horns that come off of retired locomotives that produce 149.4 decibels. There is nothing short of a ship horn that will produce above 150 decibels realistically. Authentic train horns may be heard up to 4 miles away and will blow the chrome off of any Chinese imported imitation models.

QUESTION:  IS IT ILLEGAL TO HAVE A TRAIN HORN ON MY VEHICLE?

Answer: The horns themselves are perfectly legal. However, the horns are so loud they could possibly violate local noise ordinances, just like having your radio up too loud. Naturally, if you're going around scaring grandmas and little kids all day, you might have it coming. In general, if you use common sense, you won't find yourself attracting the wrong kind of attention. Again, train horns are not illegal, you just have to watch who you scare the pants off of.

Our horns are more for safety purposes than anything else. They give the driver a voice while on the road. Road rage has become a growing problem. People can be oblivious, and at times, inconsiderate. What better way to grasp their attention, than with the power of a locomotive?

QUESTION:  EVERY TIME I BLOW THE HORN AT FIRST IT'S JUST A VERY LOUD HIGH PITCHED WHISTLE, BUT IF I HONK IT A LOT IT CONTINUES TO GET DEEPER. WHAT'S GOING ON?

Answer: It sounds like there is water passing through your horns. Have you been draining your tank consistently at the drain fitting? If not, the condensation will pool up and run through your lines upon opening the air valve. Any air horn, when accepting water from outside elements, will produce a squeaky tone. It is best recommended to mount them down, out to the sides, or pointed backward to avoid this. Also, the bells should be kept away from anything that produces a fair amount of heat, which could, in turn, build up condensation in the horns (ex. exhaust).

QUESTION:  WHAT CAUSES THE SOLENOID VALVE TO STICK OPEN?

Answer: Your solenoid valve can stick open for one of a couple of reasons. First, if the kit is newly installed, check that the arrow on the brass body of the valve is facing towards the horns. The solenoid valve is a directional valve, so if installed backward, it will cause air to constantly go to the horns, sometimes making them hum. If the valve is installed in the right direction, check the wiring and be sure the valve is not receiving a constant 12-volt charge. If it is getting constant power, it will be constantly open. If it is facing the correct way, is not getting constant power, and still won't close, check the orifice for debris that could keep it from closing. If it is below freezing where you are located, it is possible condensation inside of the system has frozen and is preventing the valve from closing.

QUESTION:  AFTER INSTALLING, MY VALVE STAYS OPEN WHEN I FLICK MY TOGGLE SWITCH. I THOUGHT IT WAS SUPPOSED TO BE OPEN WHEN I PRESS THE STEERING WHEEL?

Answer: This is a wiring issue. The solenoid valve should only open when power is sent to it. If you wired up your switch to work with the OEM horn button, you may have done so incorrectly. If you have it wired up to your horn wire, it should only honk once the horn button is depressed. Double-check that you spliced into the horn wire and not constant power by accident.

QUESTION:  WILL THE MANUAL VALVE WORK ON MY SYSTEM?

Answer: The manual valve will work just fine with your air horns. However, it is a 'manual' valve, so expect to drill holes to run air line inside your vehicle. This valve will allow you to play with the tone of the horn, unlike an electric valve, which strictly is fully open, or closed. The assembly allows adjustment between full flow and several different metered flow levels.

QUESTION:  HOW LONG DOES IT TAKE TO INSTALL ONE OF YOUR HORN KITS?

Answer: Installation can take 6-8 hours depending on how and where you plan to mount the system. If you are using one of our installation brackets, you can cut install time down to about 3-4 hours!

QUESTION:  WHAT ALL DOES THE TIRE INFLATION KIT COME WITH?

Answer:  Our Tire Inflation Kit gives you all the tools you need to air up tires or any other inflatables for that matter. Our Tire Inflation Kit includes an Air Source Relocation Kit to install a quick connect up to 15 feet away from the onboard air system, 30 feet of high-quality coil hose and a tire inflation gun with a built-in air pressure gauge.

QUESTION:  WHAT DOES THE WIRELESS REMOTE DO? DO I HAVE TO USE THAT INSTEAD OF MY HORN BUTTON?

Answer: Our Wireless Remote will activate your train horn from up to 300 feet away from the system. It is a keychain-sized remote that triggers your valve for the horns. As long as your air tank has air in it, it will even activate without the vehicle being on. Our Wireless Remote is designed to be used in addition to your standard toggle switch that comes with our kits, so you can and should use both!

QUESTION:  WHAT IS THE ELECTRIC DRAIN VALVE KIT FOR? WHAT DOES IT DO?

Answer: The only regular maintenance that needs to be done for our onboard air systems and horn kits is draining your air tank regularly. Our standard kits come with a 1/4 Drain Cock Fitting that plumbs to the bottom-most port in your tank. Usually, you would have to get under the vehicle and manually turn this fitting to drain moisture from your tank. With the Electric Drain Valve Kit, draining your tank is as easy as pushing a button from the comfort of the cab of your vehicle.

QUESTION:  WHAT'S THE DIFFERENCE BETWEEN A STANDARD AIR GAUGE AND A DIGITAL AIR GAUGE?

Answer: With standard air gauges, you need to plumb the gauge either directly to your air tank or run airline in and out of your cab to mount it in your cab. Out Digital Air Gauge instead allows you to run wire from a special fitting on your tank to the cab so you can constantly monitor your air pressure. Upgrading to a Digital Valve allows you to get rid of the need to run airline to the cab and makes for a much easier and cleaner install.

QUESTION:  DO I HAVE TO GET RID OF MY SPARE TIRE TO USE THE SPARE TIRE DELETE BRACKET?

QUESTION: WHAT IS AN AIR BAG?

Answer:  An air-spring (also known as an air bag or air bellow) is a column of air confined within a rubber and metal (or ABS) container that is placed between the frame of your vehicle and your vehicle's suspension. Air is forced into the air spring to expand it and raise the height of the vehicle and expelled from the spring to deflate it and lower the height of the vehicle.

QUESTION: WHAT ARE AIR BAGS USED FOR?

Answer:  Air Springs can be used in heavy-duty vehicles to increase load-carrying capacity, used to raise or lower the ride height of a vehicle, and used to give your vehicle a smoother ride.

QUESTION: HOW CAN I BENEFIT FROM AIR SUSPENSION ON MY VEHICLE?

Answer:  Any vehicle can benefit from a smoother ride. Air ride makes your vehicle absorb less shock from the road and some of the more advanced systems can constantly keep your vehicle at your desired height even while turning or stopping. If you have a pick-up truck or heavy-duty vehicle, you can easily increase the vehicle's load-carrying capacity by adding air springs to the rear.

QUESTION: MY VEHICLE RIDES ROUGH. WILL ADDING AIR SPRINGS IMPROVE MY RIDE?

Answer:  Yes! Air springs are engineered to increase ride quality when carrying heavy loads and help fatigued springs ride smoothly. Air springs greatly improve the ride of larger trucks and the full suspension kits that we offer give you support and customization that you just won't find with stock suspension.

QUESTION: CAN AIR SPRINGS RAISE OR LOWER MY VEHICLE?

Answer:  While adding air can cause your vehicle to ride an inch or two higher, air springs are not designed to raise your vehicle above factory height. If you want to lower your ride height, we do carry air spring systems designed to replace your existing suspension for lowered stance and higher performance.

QUESTION: WHAT KIND OF SUSPENSION KITS DO YOU OFFER?

Answer:  We offer load support and custom air suspension parts.

QUESTION: CAN I ALSO USE THE HORN KIT TO RUN THE AIR BAGS ON MY VEHICLE?

Answer:  That depends on the onboard air system you get and what kind of suspension you are running. If you are going to be running just rear bags for load leveling you won't need a lot of air volume. If the system you choose contains a constant duty air compressor it will have no issues running airbags as well as horns. Just keep in mind if you are going to be controlling your air suspension for all 4 corners of the vehicle you would use a lot more air volume. If you use all of the air in your tank (like laying on the horn until the tank is empty) you could deflate the bags in the process.

QUESTION: WHAT HAPPENS IF I RUN OUT OF AIR IN MY TANK WHEN I HAVE AIR BAGS?

Answer:  If you use all of the air in your tank (like laying on the horn until the tank is empty) you could deflate the bags in the process. If you plan on using the horn often and you have a four-corner suspension, it may be a good idea to go with as large of a tank possible to give you the most amount of air possible to the tank doesn't empty out easily.

QUESTION:  CAN I PLAY MUSIC THROUGH THE HORNBLASTERS 100 WATT PA SYSTEM?

Answer:  Absolutely! There is an auxiliary port for audio input that may be used with any standard auxiliary cable.

QUESTION:  WHAT DO THE AUXILLARY SWITCHES DO?

Answer:  The auxiliary switches on the PA system can be used with any accessory that incorporates an auxiliary on/off switch, but no sound. This would allow you to add additional accessories to your vehicle and turn them on/off with the PA itself.

QUESTION: IS THE HORNBLASTERS 100 WATT PA SPEAKER ITSELF WATERPROOF?

Answer:  The speaker included in the HornBlasters 100 Watt Public Address System is water-resistant, but not waterproof. You can mount the speaker in the engine bay or behind the grille and not have to worry about it getting wet. Just be careful that it’s not in contact with anything hot. It will melt the enclosure. Ensure the speaker is not facing straight up when you mount it to prevent puddles from gathering in the unit. If the speaker becomes submerged in any way it will sustain great damage and void the warranty.
