Shanghai Rotorcomp supplying oxygen compressor is completely oil-free and does not use any lubricating oil.

The cylinder uses stainless steel and the piston ring is self-lubricating. All these ensure the cleanliness and pollution-free of oxygen.
The working speed of the compressor is very slow, usually 200-400 rpm, suitable for continuous working conditions for 24 hours.

Generally, according to the customer’s oxygen usage, our oxygen compressors have one-stage compression, two-stage compression, three-stage compression, four-stage compression, and five-stage compression in the form of cylinders, which are single-cylinder,

Thanks to their oil-free, dry-running and gas-tight design, Shanghai rotorcomp compressors are ideally suited for use in the compression of oxygen.

• no gas contamination due to oil-free and dry-running compression
• Safe operation through the use of special, oxygen-compatible materials
• technically tight gas compressors during operation and at standstill
