35" TIRES DON'T STAND A CHANCE!

Want to be able to air up your tires without having to worry about installing an entire onboard air system? With the Viair 400H Hardmount Air Compressor, you get the on-demand air that you need straight from the compressor. No tank needed! Fill up directly from an air chuck attached to the included 1/4" Quick Connect Stud. Producing a massive 2.3 CFM flow at zero PSI head pressure, Viair 400H easily fills a 35” X 12.5” tire from empty to full in under five and a half minutes.

The Viair 400H comes with a built-in, moisture resistant ON/OFF power switch, remote mount air filter assembly, heavy-duty stainless steel leader hose with a 1/4” quick connect stud for hookup to a coil hose, and insulated wiring for simple installation. 

Note: Use thread sealant for proper installation. Thread tape is not recommended. Properly sealed, recommended torque for 1/8″ is 10 ~ 11 ft. lbs. Recommended torque for 1/4″ and 3/8″ is 12 ~ 15 ft. lbs.
