Datasheet

Product overview

Power: 37 / 45 kW reference models · Pressure: 7 / 8 bar paired variants · Flow: 5.5–7.0 m³/min across stated models

SCR's GPM2 product page describes high-speed direct-drive, two-stage oil-free screw compression with permanent-magnet drives and adjustable first- and second-stage speeds. The page also describes oil-cooled motors; oil-free compression and motor cooling refer to different parts of the machine.

For consistent headline/table examples, 37 kW SCR50GPM2-7 lists 6.0 m³/min at 7 bar and SCR50GPM2-8 lists 5.5 at 8 bar. The 45 kW SCR60GPM2-7 is 7.0 m³/min at 7 bar and its -8 variant is 6.5 at 8 bar. Keep the pressure and model suffix together. Request the actual selected machine's capacity reference, full load/control curve, total electrical input and test conditions.

Select this route when the process requires an oil-free compression air path at an appropriate larger flow duty. Specify pressure dew point and point-of-use air quality separately: drying, filtration, receiver and distribution conditions are still part of the delivered system. If certified Class 0 air is required, obtain the certificate and test scope for the exact offered model, operating conditions and required system boundary.

Provide pressure, normal/peak/minimum demand, operating hours, inlet/ambient/altitude, cooling and electrical supply. Agree stage/control protection, sequencing with existing machines, installation/maintenance access and cooling-air discharge. Request performance and air-quality acceptance conditions, commissioning, destination documentation and the offered model's maintenance and parts plan. No generic energy-saving percentage or blanket certificate is used as a guaranteed project result.

Specifying a Oil-free duty

DutyWrite on the RFQ
Class 0 oil-free compressor Class 0 means a stated test method at a stated point in the air system. An oil-free airend without a paper is not Class 0 on this desk.
Oil-free screw compressor manufacturers in China Oil-free screw is a different factory from oil-injected screw. Dry airends and water-lubricated airends are also different quotes. Name the architecture.
Compressor for a food factory Food air is a validation file. Class, test point and treatment matter as much as kW. A general 8 bar screw without papers is not a food quote.
