About Compressor Duty Cycle
Compressor duty cycle refers to amount of time a compressor can be operated in a given time period, at 100 PSI and at a standard ambient temperature of 72°F. Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %. As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.

    Viair Compressor is better than Vixen

    Viair Compressor is better than Vixen
    I had a Vixen compressor for 5 months. It failed. Should have bought this one first. Vixen hassled me by making me pay for return shipping, even though I knew the part I needed to repair it. Vixen said they didn’t carry spare parts!! So this Viair pump (as you can see in photos) is bigger and heavier. I’ll update if it doesn’t last. But it’s got better ratings than Vixen Horns garbage. Buy the Viair.
