Viair 444C Air Compressor

The go-to constant duty compressor for years, the Viair 444C Air Compressor has been trusted to power some of our most popular train horn kits throughout the years. As one of the hardest working compressors we offer, the Viair 444C features a 100% duty cycle at 100 PSI, allowing your system to power air suspension, tire inflation, air tools and more in addition to powering your horns. While not as fast as some other Viair models, the Viair 444C still boasts impressive performance for its class, providing 1.76 CFM output. The Viair 444C will recharge a 2.5-gallon tank from 165-200 PSI in just over a minute and a half and recharge a 5-gallon tank in just under three minutes. 

The Viair 444C Chome 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.
