Topic tags/keywords: spray gun air compressor

I just thought after reading a forum about compressors and Spray guns that perhaps a bit of interesting facts to those who are interested might help: (maybe more for the professional than the hobbyist, but still stuff to think about).

A Piston compressors life is an average, even after a number of overhauls about 25000 -30000 hours.

The Piston compressor is a bit more susceptible to wear and tear compared to screw compressors because of the valves and the larger friction cross section, especially in a dirty or dusty enviroment.

The Air in a piston compressor has an average temperature of 150 to 170 deg. Cel. This means that lots of condensation can build up, so the proper size dryer or desiccant is needed.

In a typical oiled piston compressor there is 20 to 35 mg/ cubic meter air.

A piston compressor looses constantly on the effectiveness or effeciency. Every year on average a piston compressor looses 3 to 5% of its ability to produce pressed air.

Back in my mechanic days the shop I worked at had a large compressor, I wonder if they ever measured the wear on it? Thanks for the facts about compressors.
