The standard compressor option that's included with Bag Riders full kits and management packs now comes in a black finish! Although the 400C is louder than other compressors like the 380C and the 444C, it's quicker and puts out 2.54 CFM at 0 PSI with a 33% duty cycle at 100 PSI. When it comes to 150 PSI applications, the Viair 400C is the best bang for your buck.
