T30 horizontal top end rebuild?
by Tim Thery
I have a T30 horizontal Two Stage Model #71T2 10 hp. The compressor will start up, and run up to about 50- 60lbs then the low end relief valve opens. The pressure switch is set at 70lbs on low end and the high end is set at 120lbs psi. when the compressor is shut down it leaks air thru the intake. and the relief valve flutters until pressure gets below 50lbs. any suggestions or questions?
