This standard covers the minimum requirements for double-acting reciprocating compressors of 600 brake horse power (448 kilowatts) and below used in refinery services with lubricated or nonlubricated cylinders in utility air and/or instrument air service up to 125 pounds per square inch gage (8.6 bar). Driver, related lubricating systems, controls, instrumentation, intercooler, aftercooler , receiver, and other auxiliary equipment are covered in this standard. The compressor will generally be spared.

CAUTION: Compressors intended for instrument air service require dry cylinders to supply oil-free air. Compressors used in plant air service can be either of the dry-cylinder or lubricated-cylinder type construction. Because air/oil mixtures may ignite, the purchaser/user is cautioned of the need to carefully select the cylinder lubricant and consider all operating conditions. Temperature criteria are described in 2.3.

NOTE: A bullet (*) at the beginning of a paragraph indicates that a decision by the purchaser is required. These decisions should be indicated on the data sheets (see Appendix A); otherwise, they should be stated in the quotation request or in the order.
