SF6 Compressor Questions

GNR oil-less compressors have been developed for the exacting requirements of safe, reliable industrial gas compression service, such as SF6 gas, helium, hydrogen and noble gas.

Yes. They are complete oil-less piston compressors with a gas-tight design and special sealing, so no lubricant enters the gas stream.

Standard models are designed to 600 psig. The published model chart lists a discharge pressure of 51 bar for the GNRD-6, GNRS-25, GNRS-30 and GNRX-80.

The compressor has a pressurized sealed crankcase option to allow for suction pressure up to 9 bar.

Air-cooled throughout — heat exchanger, compression cylinders and crankcase are all air cooled, so no cooling water circuit is needed.

The standard model chart runs from about 6 Nm³/h on the GNRD-6 up to about 80 Nm³/h on the GNRX-80, with motor power from 2.2 kW to 22 kW.

Yes. Weiyang specializes in solutions tailored to the specific needs and requirements of the end-user’s application, either by aligning your requirement with one of the standard configurations or by tailoring the compressor and control system design to your exact specification.

An explosion-proof compressor version is listed among the features of the SF6 Gas Compressor.
