What is an oil-free process compressor?

Oil-free process compressor is a clean compression subdivision equipment under piston type, which cancels the lubricating oil circuit of cylinder and relies on self-lubricating piston ring to complete gas compression. The compression medium does not contact lubricating oil in the whole process, which is specially used for production process scenes with strict standards on gas cleanliness. It is an irreplaceable pressurization equipment for medicine, electronics, food and special chemical industry.

Core special requirements include:

Zero oil pollution of gas source: the piston and guide ring are made of PTFE composite wear-resistant material, no lubricating oil is injected into the cylinder, and the oil content of exhaust gas is ≤ 0.01 mg/m, which meets the production standard of high purity gas;

All-medium adaptive seal: the cylinder, intake valve and exhaust valve are made of stainless steel and Hastelloy, which can compress various oil-free media such as oxygen, nitrogen, carbon dioxide and ethylene oxide;

Simplify the operation and maintenance structure: oil-gas separator, oil filter element and lubricating oil filling replacement components are omitted, no waste oil is generated, and the cost of environmental protection treatment is reduced;

High-temperature protection design: the self-lubricating ring is modified at high temperature, and a multi-stage interstage cooler is equipped to avoid the wear and failure of seals caused by high temperature;

Explosion-proof optional configuration: For combustible media, it can be equipped with a complete explosion-proof electrical system to meet the explosion-proof specifications for the production of chemical hazardous chemicals.

Summary: this model has outstanding advantages in clean production track with its high-purity output characteristics; The short board has higher procurement cost and limited heat dissipation at full load for a long time under the same displacement, which is more suitable for the working conditions of small and medium flow and continuous clean gas use.
