Description

VIAIR Heavyweight Portable Air Compressors are designed for serious RV enthusiasts, rock crawlers and anybody who has ever had to tow anything and gotten a flat along the way. Heavyweight Compressors are easy to use just attach the included leads to your 12V vehicle battery or power source, power the compressor on and start inflating. The 400P-RV makes it even easier for RV owners to keep their home on wheels rolling with the included 33 feet of primary hose and 25 feet of quick connect extension hose (not to mention the included 45 and 90 degree tire chuck/inflator/deflator). Each compressor comes with its own deluxe carrying case for added convenience and portability, as well as a 3-pc inflation tip kit that enables you to inflate a whole host of tires (up to 35 inches) in less than 5 minutes!

Frequently Asked Questions

Q: What is CFM?
A: The notation CFM (Cubic Feet per Minute) refers to a volume of air produced by the air compressor at a given pressure or PSI (Pound per Square Inch)

Q: What is Duty Cycle?
A: A compressor's duty cycle determines the percentage of run time in a full cycle. A full cycle is determined by adding the compressor run time to its rest time.

Q: 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?
A: No, you've got to remember that duty cycle is rated at 100psi, at an ambient temperature of 72F, but certainly a 100% duty cycle compressor can run for much longer periods of time than a 30% duty compressor under the same conditions.

Q: Does a new compressor have to be broken in?
A: No, they do not. Typically after an install, you should power up the system from 0 to whatever the cut-off pressure is and check for any leaks that may be present.

Q: Does it matter where I install my compressors on my vehicle?
A: This depends on several factors such as available space, whether or not the compressor is of a sealed or vented type, as well as personal preference and aesthetics. Make sure to utilize the rubber insulators to keep vibration and noise to a minimum.

Q: How can I tell whether the compressor is sealed or non-sealed?
A: Manufacturers will normally specify if a compressor is sealed against moisture and dust, and in many cases, you can tell the difference by simply inspecting the compressor. If you see vents, cracks, or holes in the motor housing, then the compressor is not sealed and must be kept away from dust and moisture.

Q:Why is it important to have a sealed and moisture-resistant compressor?
A: The preference of a sealed-type compressor is due to the fact that in mobile pneumatics, compressors are likely to be exposed to outside elements.

Q: Is it possible to mount the compressor sideways? Must it be mounted with the cylinder upright?
A: Yes, you can mount our compressors in any direction or position because they are oil-less. The only position we do not recommend is an upside-down mount, since heat tends to travel upward.

Q: If I mount my compressor sideways, like on the frame rail of my truck, is there anything I should be careful of when doing this?
A: If you mount your compressor sideways to the frame rail, you should periodically check to make sure that your compressor is mounted securely. Use a thread-locking compound to keep the screws from backing off and causing the compressor to be mounted loosely.

Q:What is the largest air tank recommended for your compressors?
A: We recommend up to a 5 gallon tank for the 325 and higher series compressors.

Q: Is it possible to hook up more than one compressor to a single pressure switch?
A: Yes, it is possible to use one pressure switch on more than one compressor. You should always run a relay if you want to hook up multiple compressors to a single switch. You should check the amp draw on the switch first, and then you'll know how many compressors you can hook up to one switch.

Q: Can I use an adjustable pressure switch with my compressor?
A: We don't recommend that you use adjustable pressure switches with any VIAIR compressor. If you use an adjustable pressure switch, you can set the pressure switch higher than the maximum pressure that is rated for your compressor, or you may exceed the maximum rated working pressure for your air supply tank. Doing so will immediately void your warranty, not to mention, it is dangerous.

Q: Is amp draw of the compressor something I need to be concerned with?
A: Yes, the lower the amp draw, the better the compressor is. As a rule of thumb, the maximum amperage that a compressor should require is 30amps.

Q: Is there a way to increase the flow rate of my compressors, and improve my compressors' performance as well?
A: When using an onboard air system with multiple compressors such as P/N 38002, always plumb each compressors's leader hose to separate tank port. Doing so will increase flow rate by up to 20%, which will also increase your system's level of performance.

Purchased this compressor for my fifth wheel . Most tire failures are caused by low air pressure . My tires require 80psi and most small portable compressors just can't handle it . This one does it fast with power to spare.

I received the product very quickly after my order. The product is high tech, and from reviews highly reliable for a motorhome for which I bought it. VIAIR says it was build with the RVers in mind. I have tried it once on my family automobiles and it has worked superbly...very fast and I am amazed at how quite it runs. It has long hoses but I may have still to find an air hose extension for the left real dual tires. I actually though that it had an extension as a part of it but apparently not. I did not air the tires up on the motorhome because they did not need it at this time.
