Oxygen Booster Pump

Working principle

A fully oil-free oxygen booster is a reciprocating plug, this product does not need to be added lubricating oil, no pollution of pressurized oxygen, full sealing structure, no leakage operation. All bearing added imported special grease to ensure the product durable.

Oxygen compressor consists of main engine, motor, instrument and electrical control elements.

When the supercharger is working, the motor drives the crankshaft to produce rotating motion through the triangle belt drive, and the piston produces reciprocating motion through the connecting rod, which causes the cylinder volume to change, resulting in the increase of oxygen pressure in the cylinder. Oxygen is injected into the buffer tank through the exhaust valve, one-way valve and pipeline for use.
