The USR C3 Air Compressor is a budget-friendly constant-duty air compressor, making it perfect for automotive applications. Designed for 0.5 to 1.5GAL air tanks in order to work at optimal power. With a 25% duty cycle at 100 PSI, the USR C3 is great for pneumatic applications such as air horns, emergency tire inflation, and air suspension. The USR C3 also has solid refill times for a constant duty compressor, able to recharge a 2.5-gallon tank from 110-150 PSI in only 1 minute and 35 seconds and recharge a 5-gallon tank in just over 3 minutes and 15 seconds.
The USR C3 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. It also includes a standard 1/4″ NPT stainless steel braided leader hose with a check valve and insulated wiring for fast installation.
It manages 1.87 CFM and works optimally for air tanks from 0.5GAL to 1.5GAL.
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.
