The best of both worlds, the Viair 425C Air Compressor gives you a fast-fill compressor that is 175 PSI capable, with an exceptionally long duty cycle. The 425C Viair’s first compressor with a duty cycle of 33% at 175 PSI, and 50% at 100 PSI. Coupled with a 2.4 CFM output and you have one of the highest performing compressors on the market today. The Viair 425C can recharge a 2-gallon tank from 140 to 175 PSI PSI in an insane 42 seconds and recharge a 5-gallon from 140 to 175 PSI tank in just under 2 minutes. The Viair 425C features a newly-developed sleek head design, increased duty cycle and even runs quieter than ever before.

The Viair 425C Air Compressor comes complete with a remote mountable intake filter assembly, or “Air Snorkel Kit”, allowing the air intake to be moved to use clean air even if the compressors are mounted in the way of debris, moisture, and other air system contaminants. Includes a standard 1/4″ NPT stainless steel braided leader hose with check valve and insulated wiring for fast 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.
