Viair 400P Portable Compressor is a larger portable compressor kit that can inflate up to a 35 inch tire from 0 to 30 PSI in less than 5 minutes by simply attaching its supplied heavy duty battery clamp power leads to the battery, attaching the lever style air chuck to a tire valve stem and turning the unit on. Air pressure can be monitored using the 5-in-1 inline inflator/deflator hose and gauge included. Always turn off the unit to take an accurate pressure reading since air flow into the tire will show an inaccurate pressure reading while the compressor is running. Used and approved of by off road enthusiasts worldwide. Let compressor cool off for about 30 minutes to allow thermal overload reset

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.
