This compressor setup is designed for both airing up and down of tires. The 400P can air up a 33inch x 12.5inch tire from 15 to 30 PSI in about 2 minutes. The 400P easily clamps onto your battery, has an inline 40 amp fuse for protection and also features an automatic reset thermal overload protector. It is also a moisture and dust resistant, built on a heavy duty stand with vibration isolators and includes a 150 PSI gauge on top. Includes deluxe, dual compartment bag.
The 400P is a 33% Duty Cycle portable with built-in automatic function. When you have the gas station tire gun lever depressed, air flows as normal. When released, pressure builds in the air line and shuts the compressor off safely at 150 PSI. To start again, simply squeeze the inflation lever on the tire gun to resume tire inflation.
