engine driven compressors..good or bad?

if youve gone threw 2 already someones doing something wrong i ran one on  my nissan for 3 years and before that it was on my mazda for a year and it was a used junkyard york and the time i ever checked or changed oil was when i put it on my nissan and i would run it up to 250 and every once in a while id forget to turn it of and have 300+ and still not one problim

damn i wish i could run mine up to 200 or so, mine starts kinda knockin around 200 and my tank is only rated to 160 with a 500psi burst .

hey i have a 89 ranger and i heard i can turn my a/c into and engine driven can anybody help me out to

Ive got a 210 on my daily silverado.  I havent checked the oil on it for a year and a half.  Still runs strong.  You must have somthing else wrong to be having the problems you do.

ok so this sunday i change the compressor and put a new inline oil/water seperator...because for some reason wen the compressor went out it blew up the seperator.....gonna find a new inline check valve an replace it...... so tired of this shit thats wat i get for hiring a MEXICANT instead of a mexican to do the work....the guy wont even warranty the labor...........any more thoughts i would like to here them....

Are you putting brand new pumps in or used pumps?  Are you rebuilding them when they burn up or just replacing them?  I know my pressure switch is set at like 160.  Maybe you should change the pressure switch.  Im not sure why but my york has a check valve on the intake side as well as the exhaust side.

alright yeah thats what i thought i will probley just buy a york compressor thanks for the help

---------------------------------------------Originally posted by Pootusmaybe the have it spinning backwards? you really shouldnt be going thru them that fast... perhaps a plugged check valve making it struggle? kinked hose? ---------------------------------------------If it's spinning backwards, wouldn't that be trying to suck air out of the tank and not put it in?  Don't know...??

We now carry checkvalves that are designed for use with edc's....300PSI/300 Degrees http://www.waylayedinc.com/Waylayed2010/ww/products/Rockstar-1%7B47%7D2%22-Checkvalve%252dLifetime-Warranty.html
