Viair Q&A

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 a compressor all the time?

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. 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. 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 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 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.
