Step up your onboard air game with the dynamic duo of compressors, the Viair 280C Black and Silver dual-pack! One 280C is all you need for tanks up to 2.5 gallons, but why settle when you can power tanks up to 5-gallons with two? Fill your tank lightning fast, recharging a 2-gallon tank from 110-145 PSI in just 29 seconds and a 5-gallon tank in 1 minute and 11 seconds. And the best part? The Viair 280C only pulls 45 amps from your battery. Ideal for air suspension systems and powering HornBlasters train horns!
This compressor does come with the option to add our 40 Amp Air Compressor Wiring Kit to it as well!
