High-pressure gas compressors are used in one application or another in most industries. Gas producers, mass transit systems, petrochemical companies, power generation, diving, food and beverage processing, as well as glass and paper manufacturing are some examples. Diaphragm high-pressure gas compressors are superior to conventional gas compressors in many aspects.

The Differences

A diaphragm compressor is also known as a membrane compressor and can be made using rubber, silicon, or metallic materials. Rubber and silicon compressors are only used for low pressure applications because those materials cannot withstand higher pressures. It is the metallic version that is superior.

Conventional compressors are expensive, use a piston to directly displace the gas, and require a technician to re-prime the machine between separate applications. Piston rings, pistons, and the friction of the high pressure can create leaking. The result is contamination of the product and the leaking of gas into the atmosphere.

Diaphragm compressors are designed to be contamination and leak-free. Pistons move hydraulic fluid, which is the media that displaces the gas to create high pressure. That eliminates several expensive components, the need for a technician between applications, and vibrations and knocks within the machine.

Spend Less

The purchase price is lower than conventional compressors. Components are specially treated to prolong life, reducing operation and maintenance costs. Safety features reduce accidents and workplace injuries, which also saves the business money. The time savings adds up quickly as well because some solutions are fully automated, increasing productivity.


Basic versions of diaphragm compressors are extensive to accommodate most needs. Unique needs, new challenges, and issues can be resolved with custom-designed and fully automated turnkey systems. Leading manufacturers, such as PDC Machines, have designed and installed systems across the globe.

Configurations include single stage, duplex, and two-stage models. Some can be mounted both vertically and horizontally to create more horsepower without requiring more energy. Selection assistance, design consultations, and option recommendations are provided to business owners who are not sure which compressor is appropriate. Comparing existing machines with the cost and efficiency of a custom compressor system can assist owners in making informed decisions on how to move forward.
