Viair Dual 425C Air Compressor Kit

(Fast Fill – 175 PSI / 4.80 CFM)

DC-425L


The new Viair Dual 425C Air Compressor Kit brings previously unseen speed and reliability to your system two of Viair’s first compressors to feature a duty cycle of 33% at 175 PSI, and 50% at 100 PSI. This gives you a dual compressor kit that is extremely quick and can handle a hefty workload as well. With a combined CFM of 4.88, the Viair 425C is one of the most powerful compressors offered by Viair. With two you can power up to 10 gallons of air and get insane refill and recharge times. The Viair 425C's can recharge a 2-gallon tank from 140 to 175 PSI PSI in an insane 28 seconds and recharge a 5-gallon from 140 to 175 PSI tank in only 57 seconds! With speeds this fast, the Dual Viair 425C's are perfect for anyone that needs a quick and responsive system for their train horns or suspension system. 

The Viair Dual 425C  Air Compressor Kit will come 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 two standard 1/4″ NPT stainless steel braided leader hose with check valve and insulated wiring for fast installation, as well as two heavy-duty 40-amp relays and a 140 PSI cut-on, 175 PSI cut-off heavy-duty pressure switch.

This compressor does come with the option to add our 40 Amp Dual 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.
