Portable air compressors

[nissannewby]

Duty cycle should be on the label on compressor or on the box it came in.
Might even have a user manual to check

Have you owned an endless air system?

They are good yes but do require routine maintenance. Obviously the are belt driven, there are bearings and seals, they are able to be lubricated but you need to keep on top of this so the insides don't seize up.
