The Viair 325C Air Compressor is a light, powerful and budget-friendly compressor that is perfect for anyone wanting to run 150 PSI with a tank up to 5-gallons in size. Able to produce 1.59 CFM with a 33% duty cycle at 100 PSI, this workhorse medium-duty compressor is perfect for pneumatic applications such as powering an air locker, air horns, and emergency tire inflation. The Viair 325C is their flagship medium-duty fast-fill compressor for good reason, it is able to recharge a 2.5-gallon tank from 110-150 PSI in only 1 minute and 25 seconds and recharge a 5-gallon tank in just over 2 minutes and 30 seconds. Includes a standard 1/4″ NPT stainless steel braided leader hose with check valve and insulated wiring for quick installation.

The Viair 325C comes complete with a remote mountable intake filter assembly, or “Air Filter Snorkel Kit”, allowing you to relocate the air filter up to 6 feet away to keep it away from moisture and debris. Includes a standard 1/4″ NPT stainless steel braided leader hose with check valve and insulated wiring for fast installation.

This compressor does come with the option to add our 40 Amp Air Compressor Wiring Kit to it as well!

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.
