Unique Housing Construction

• Housing jackets permit cooling and assure dimensional stability.
• Removable end-covers permit easy access to timing gears, seals and bearings.

Quiet Helical Timing Gears

• Synchronized rotors with close clearances enhance long life.
• Timing gears transmit only a tenth of the driver power, resulting in negligible wear.

Lubricant-free Compression

• No oil contamination of air or gas being compressed.

Positive Displacement Compressor

• Operates over a wide range of pressures and speeds.
• Handles a multitude of gases from air to light hydrocarbons, ammonia, freon, hydrogen and nitrogen.
• Permits operation at moderate speeds, suitable for direct-connected motor drive.

Less Area Required for Capacity Range

• May cut floor space costs substantially.

No Unbalanced Forces

• Eliminates need for expensive foundation, lowering installation costs.

Rotors Do Not Touch Each Other or the Casing

• Actual compressing parts not subject to mechanical wear.
• Power requirements are less than other types of oil-free compressors in its pressure range.

• Large self-equalizing tilt pad bearings provide long wear.
• High-capacity thrust bearings handle high loads.

• Dynamically-balanced rotor assembly precludes vibration for less wear, longer life.
• Provides a continuous flow of gas without pumping or surging.
• Optional protective shaft sleeves prevent shaft wear and minimize replacement downtime.

• Operate well below first critical speed.
• Handle higher pressure differentials.
• Employ higher-speed, lower-cost drivers.

• Maintain clearance stability to allow compressor to run at higher temperatures without seizing.
• Cooling oil enters and leaves at the end of the shaft and is centrifugally forced through the bored rotor.

• Generously-sized babbitted steel journal bearings assure long life in continuous service.
• Bearings fit into precision-machined cartridges, allowing compressor to run at higher speeds.
• Conservative ratings result in long life.

• Permits cooling to assure dimensional stability (maintain clearances).
