Single Acting Reciprocating Air Compressors 15-84 kW (20-113 hp)
High Pressure Dependability
The W-series reputation has been built on quality, reliability and accessibility to all components. The W Series products are single acting W configuration and include air and water cooled three and six cylinder units.
The W-Series compressors include heavy duty cast iron construction, counterbalanced crankshaft to ensure smooth operation, deep-finned cylinders on air-cooled units and water cooled cylinders and heads on water cooled units, which quickly dissipate the heat of compression. Superior lubrication is accomplished through a gear driven positive displacement oil pump powered by the crankshaft complete with a spin on oil filter. W-series compressors are ideal for petroleum refineries, oil rigs, plant air, ore mines and well head servicing.
105 cfm-560 cfm
20-175 psig operating pressure
Single & Two Stage
Cast iron construction
Compressors are shipped without oil
Two stage compressors have an ASME pressure relief valve that protects the intercooler and first stage from over pressure
Low lift valves for volumetric efficiency and reliability.
Removable hand-hole plate allows easy access to the internal running gear.
Con Rods have two-piece insert bearings for quick and easy replacement.
Two stage units have an interstage intercooler to reduce the interstage temperature which permits low discharge temperatures.
Both air and water cooled units have features that are designed to quickly dissipate the heat of compression.
Crankshaft ends are supported by large tapered roller bearings for smooth operation and long life.
Oil pressure gauge assures the operator of lubrication system integrity.
The cylinders and crankcases are built of industrial strength cast iron materials.
Superior lubrication is accomplished through a gear driven oil pump powered by the crankshaft. The pressurized system ensures complete lubrication to the crankshaft, connecting rods, bearings and piston pins. Full flow, spin-on oil filter ensures impurities are removed before the lubricant contacts any internal components.
Oil pressure gauge is conveniently mounted to display the oil pressure.
