Commercial Grade 5 HP Compressor

[Ronald Blue]

Almost all companies make several levels of compressors. The middle one will be pretty decent and splash lubed. the top end will be pressure lubed and may or may not have a better pump. In the quincy world QT is the low end and QR is the best- maybe the best of the best. The QR 325 is the pick of the litter. I would take a used one over most new compressors any day. Don't buy any compressor that runs over 900 rpm, and 600-700 is even better. Cast iron pumps are much better than aluminum. Saylor Beall PL and Curtis Masterline are very good too. Dave

Plus 1 on the Quincy QR series. Thousands of hours of dependable service. We run either the 370 or 390 series and I don't recall which on locomotive cranes. Regular oil and filter changes and they run and run and run.

I was wrong Schulz is from Brazil and has been since the 1980's or older. still rated as a good compressor. Kellogg is a good old brand. I do not think Kaiser made piston pumps.
