The 400P is VIAIR's mid-tier portable compressor and the model that built the brand's overlanding following. 2.4 CFM at a 150 PSI cap, 33-minute duty cycle, manufacturer-rated for tires up to 35 inches. Ships with battery clamps, a 25-foot air hose, and a soft carry bag. The default recommendation for stock-to-mildly-lifted Wranglers, Tacomas, and 4Runners.
