It has a 4“low pressure bore and a 2.25” high pressure bore, witha 2.88” stroke. This compressor can be run at 400-1060 r.p.m.A hooded air f31ter/silencer is available as an option,as well as head unloaders.CHANGESsince previous printing dated December 1994:-QUIN-CIP oil information was added-piston rings were changed in the lowpressure piston group-cylinder & head groups were changed-updated control groups were added- unit parts information was added.(3T.fi-.”fQUINCYCOMFI?ESWR50230-104 1 November 1996
