The new 460 is Viair's new replacement for the 450. It comes with a fat 3/8" leader hose instead of the old 1/4". This compressor is 100% duty cycle, and fills a 5 gallon tank to 145 PSI in 2 mins 10 sec. Extra filters, airline, and mounting hardware included. "VIAIR warranties only compressors that have been installed using their installation instructions included with each compressor. Installation of an adjustable pressure switch can allow compressors to operate beyond their rated duty cycle and working pressure. Use of an adjustable pressure switch will void the warranty on any VIAIR compressor."
