compressor prob

i have a viair 380 i do belive 100% duty cycle and i guess i ran it a lil to hot and it has a shut off im guessing well anyways after i let it cool off it just wont run as good its like its bogging down does anyone know what going on does it need to be rebuilt? any help would be apreciated

yea it was new and now it seems as if it is wore out i just dont understand what the prob could be

just because a compressor is rated at 100% duty dosent mean it can run 24/7
the duty cycle is rated at a low psi and most time free flowing with no back pressure
also the viairs are sealed units except for the 500 series if i remember rights so they can be mounted i any position
