Notes:
1. Estimated flow/suction based on approximately 4,700 psi (324 bar) compressor discharge
2. Flow/power based on 1,780 rpm with SG of 0.65 and K-value of 1.24 (@ STP)
3. 1 SCFM = 1.7 m3/h, 1 psi = .068 bar, 1 HP = 0.746 kW
4. Suction pressures indicated are at compressor package inlet
5. GGE (gallon of gasoline equivalent) = SCF/125
6. 1,780 rpm = 60 Hz; 1,480 rpm = 50 Hz (flow and power decrease ~20% from 60hz model)
7. Notes and chart apply to corresponding graphs

Key design features
• Proven field technology for high strength and longer
life – operating 24 hours a day, seven days a week
• Balanced opposed design minimizes vibration by
equalizing the opposing reciprocating forces on the
crankshaft
• Flexible cylinder configurations for field replicable
cylinder solutions to maximize suction pressure
inputs to system for increased efficiency
• Patented roller bearing technology to accommodate
fluctuations in inlet gas pressures and temperatures.
Most flexible solution to meet demands in the field
