I just picked up a Ingersoll Rand Model 234 2-stage air pump, serial #24893. It is from an older (1970-80's) 7.5hp motor compressor unit and pumps ~13 cfm at 175psi. It seems to be in good shape (crank turns smoothly and cylinder bores not too worn). The last owner took it apart and loosely assembled it. He never ran it although the original owner used it for bodywork. The IR website does not have a manual for it (just the pumps currently manuf.) but does give torque specs for similar pumps. Does anyone know a manual source or a picture of the air line routing? (the lines that came w/ it seem to be for another pump) This should improve the air supply considerably over my Champion single stage pump when I do glass beading of small parts and media blasting of the Dodge body. Thanks.
