Reciprocating Compressors
Reciprocating Compressors are positive-displacement units in which a piston compresses air in a cylinder and discharges it to a receiver or distribution line, common in workshops. They differ from rotary screw compressors, which use a pair of intermeshing rotors, each technology suiting a different duty pattern; select by required pressure, flow and duty level, single- or multi-stage design, and lubrication and drive type (belt or direct).

About this category
Reciprocating compressors are positive-displacement air compressors in which a piston moves back and forth within a cylinder; on the intake stroke, an inlet valve opens to admit air into the cylinder, and on the compression stroke the inlet valve closes and the trapped volume is compressed and discharged through an outlet valve toward an air receiver or distribution line. Models differ in stage count between single-stage and multi-stage, in cylinder count, in cylinder arrangement, and in lubrication design between lubricated and oil-free architectures. Drive systems vary between belt drive and direct drive depending on the model, and a single drive system should not be assumed across the category. Documented pressure and flow values vary by model, as do the capacities of accompanying air receivers. Reciprocating compressors differ from rotary screw compressors in operating principle; screw compressors use a pair of intermeshing rotors, which makes each technology suited to different applications. Centrifugal compressors and small hand compressors are excluded from this category. Industrial buyers select reciprocating compressor models based on required pressure and flow, duty level, lubrication design, power supply and site requirements.
