Gas Screw Compressors – HG10-and-HGF10 Series
Models HG10000 and HGF10000 Non-Geared
LeROI provides rotary screw compressors for gas to the oil and natural gas, and industrial and process industries. Rotary screw gas compressors are very cost-effective for handling high volumes of gas in field gathering, vapor recovery, and a wide range of other applications.

Benefits & Performance
BENEFITS
The HG10 and HGF10 Series are suitable for applications to 90 BHP (67 KW) and 350 PSIG (24.1 BARG) discharge pressure.
Low maintenance and high reliability are inherent with rotary screws when compressing natural gas because they have few moving parts. There are no valves, rings or packing to wear out or cause loss of efficiency.
Smooth operation results from no unbalanced forces and no pressure pulsation. No foundation is required. There are no piping vibrations from pressure pulsation.
Natural gas engine or electric motor drives are equally acceptable with rotary screw gas air compressors.
LeROI Gas Screw Compressors are available in 13 models covering a flow range of 20 (0.4 M3/min) to 15,000 MSCFD (300 M3/min) and horsepower from 10 (7.46 KW) to 800 (596.8 KW).

FEATURES & SPECIFICATIONS
FEATURES
The HG10 can be belt driven or direct coupled to electric motors for maximum flexibility at minimum cost. The natural gas compressor shaft bearings can absorb the belt side load without additional pillow block bearing supports up to 30 HP (22 KW). The HGF10000 is suitable for direct coupling to engines and electric motors.
Single-Stage operation from 20 PSIG (1.38 BARG) inlet to 350 PSIG (24.1 BARG) maximum is possible with the HG10 and HGF10 Series oil-flooded compressors. Compressor packages are therefore simple, reliable and inexpensive.
The gas differential pressure provides oil circulation for proper lubrication at differential pressures over 70 PSI (4.82 BAR). An auxiliary oil pump is required on applications below 70 PSI (4.82 BAR) differential pressure.
Discharge porting can be selected to match the internal compression to the application requirement for maximum compression efficiency.
All iron or steel construction with no copper or copper alloys makes these compressors compatible with natural gas, sweet or sour.

OPTIONS & APPLICATIONS
OPTIONS
- Internal Volume Ratio: Three volume ratios are available for matching compressor performance to pressure conditions.
- High Ratio – 4.4
- Medium Ratio – 3.0
- Low Ratio – 1.9
- Versatrol Internal Bypass Valves
- Fan Shaft: A fan shaft is available for use with a direct mounted fan (side load is not acceptable so cannot be used for belt drive).
- Oil Pump: Integral oil pump is available for low-pressure differential applications, with or without fan shaft.
- SAE # 3 Bell Housing: Modules with oil cooler, aftercooler, gas/oil reservoir assembly, thermal valve, fan, oil filter assembly, minimum pressure valve and sight glass are all mounted on a steel subbase with connected components. Drive motor, belts, pulleys, guard and electric motor driven cooling fan are also available.
APPLICATIONS
