High-Purity O2 Compressor Oil-Free Acetylene Ethylene Propylene Diaphragm Compressor for Car

Product Description

The High-Purity O2 Compressor Oil-Free Acetylene Ethylene Propylene Diaphragm Compressor is a top-quality compressor designed specifically for car applications. It is manufactured with precision by HangZhou CHINAMFG Gas Equipment Co.,Ltd, a trusted supplier of gas equipment. This compressor is part of their extensive range of compressors, including diaphragm compressors, piston compressors, oxygen generators, gas cylinders, and nitrogen generators. The company is known for delivering products of excellent quality at competitive prices.

Process Principle

The Hydrogen Diaphragm compressor is carefully selected based on the user’s requirements to ensure optimal performance. The compressor’s metal diaphragm completely separates the gas from the hydraulic oil system, guaranteeing the purity of the gas and preventing any contamination. Advanced manufacturing technology and precise membrane cavity design contribute to the diaphragm’s long service life. The metal diaphragm group effectively isolates the process gas from the hydraulic oil and lubricating oil parts, maintaining the gas’s purity.

Main Structure

The diaphragm compressor’s structure consists of various components, including the motor, base, crankcase, crankshaft linkage mechanism, cylinder components, crankshaft connecting rod, piston, oil and gas pipelines, electric control system, and other accessories.

Gas Media Type

The compressor can handle a wide range of gases, including but not limited to ammonia, propylene, nitrogen, oxygen, helium, hydrogen, hydrogen chloride, argon, hydrogen sulfide, hydrogen bromide, ethylene, and acetylene. This versatility makes it suitable for various applications, such as nitrogen diaphragm compression, bottle filling compression, and oxygen diaphragm compression.


  • No leakage: The compressor’s membrane head is sealed by a static “O” ring, ensuring no gas leakage during compression.
  • Corrosion resistance: The compressor membrane head is made of 316L stainless steel, and the diaphragm is made of 301 stainless steel, providing excellent resistance to corrosion.
  • Reduced tightening torque: The “O” ring seal reduces the flange bolt tightening torque, resulting in shorter shutdown maintenance times.

The diaphragm compressor consists of three diaphragms that are clamped along the surrounding area by the hydraulic oil side and the process gas side. The hydraulic driver in the film head drives the diaphragm, allowing for the compression and transportation of gas. The compressor is divided into two systems: the hydraulic oil system and the gas compression system, with the metal membrane separating these two systems. The compression process involves two steps: the suction stroke and the delivery stroke.
