The C1 bare compressor pump is a full cast iron reciprocating compressor pump. The internal factory part number for this pump is 1312100706 and may sometimes be shown as 1312-1007-06 or 1312 1007 06.
This pump includes a finned intercooler but does NOT include an air cooled aftercooler. The intercooler helps remove much of the heat displaced after the air is compressed in the low pressure piston. Disc and spring valves are utilized inside of the pump rather than reed or finger valves. Disc valves are more reliable and can be changed without pulling the entire pump apart. This pump is designed to displace 18cfm when paired with a 5hp motor and can displace 24cfm when paired with a 7.5hp motor.
Many compressor manufacturers use the CA1 piston compressor pumps. These manufacturers include Chicago Pneumatic, Atlas Copco, Quincy, BelAir, ABAC, and NAPA.
