JY High Pressure Compressor

J-Series Reciprocating Air Compressors

Oil-free & lubricated technology 19-559 kW (25-750 HP)

This industrial air compressor can be V-belt driven by electronic motors, a variety of engines/turbines, or direct coupled. V belt drives can be utilized for most applications up to 350hp for this high pressure industrial air compressor. Four different configurations for the J-Series are available, ensuring you will get the right reciprocating air compressor for your application.


JV "Vertical" Configuration

Our single-cylinder vertical compressor is designed for maximum value vale, versatility and space savings. JV compressors are designed to be applied to a variety of industrial and process applications and are available as double-acting, single-stage, low to medium pressure units

JH "Horizontal-Opposed" Configuration

In areas with height restrictions, our two-cylinder horizontal opposed design has the counter-weights and cylinder arrangement necessary for smooth operation and balanced primary and secondary forces. JH compressors are universally used in all industrial and process applications and are available as single-stage, low pressure, high volume units and as multi-stage high pressure machines.

JY "Wye" Configuration

In our two-cylinder wye-type design, primary and secondary forces are balanced by counter-weights and cylinder arrangements for smooth operation and minimal space requirements. JY compressors are universally used in all industrial and process applications and are available as single-stage, low pressure, high volume units and as multi-stage high pressure machines.

JR "Semi-Radial" Configuration

In this unique semi-radial design, 4 cylinders are spaced semi-radially around the frame to balance forces for minimum vibration and smooth, quiet operation. JR compressors are recommended for continuous heavy-duty conditions. They can be furnished as single or multi-stage unit for low and high pressure service.


Benefits at a glance

  • All cylinders and cylinders heads are made of dense, grey iron. 
  • Pistons are designed for specific applications, to work in harmony with cylinder contouring or maximum gas flow efficiency.
  • Low-profile valves with stainless steel discs provide large port are and low velocity, resulting in a minimum pressure drop. 
  • The crankshaft is a precision machines and ground ductile iron casting or alloy steel forging, accurately counter-weighted to minimize vibrations, noise and wear.
  • The main frame's heavy cast grey iron construction provides rugged support for the running gear. Removable oil-tight covers provide generous access to crankshaft connecting rods and crossheads.
  • The box-type, cast iron, precision-fitted crosshead with extra large bearing area is rifle-drilled for pressure lubrication.
  • Heat-treated connecting rods are rifle-drilled for pressure lubrication to precision steel-backed, tri-metal crankpin bearings and bronze crosshead pin bearings.
  • Main bearings consist of precision machined and ground, self-aligning, antifriction, spherical roller bearings, which never need adjustment, so machine operation stays smooth and trouble-free.
  • Cross-head guides are one-piece construction cast of special iron alloy. Running surfaces are honed to a minor finish and pressure lubricated for long life.
