Diaphragm compressors are positive-displacement gas compressors that use a flexible diaphragm to compress process gases while separating the gas from the drive mechanism. This design helps prevent oil contamination and makes diaphragm compressors suitable for high-purity, toxic, corrosive, reactive, flammable, and specialty gases.
They are used for gas filling, transfer, pressure boosting, storage, and industrial gas supply. Browse BluNet’s diaphragm compressor products below to compare available models and specifications.
Types of Diaphragm Compressors
Diaphragm compressors can be selected according to the gas being compressed. Gas properties affect materials, sealing, pressure requirements, and compressor configuration.
| Gas Type | Typical Applications |
|---|---|
| Hydrogen Gas Compressors | Hydrogen compression, storage, filling, transfer, pressure boosting, and hydrogen supply systems. |
| Helium Gas Compressors | Helium recovery, transfer, filling, pressure boosting, and high-purity gas applications. |
| Nitrogen Gas Compressors | High-purity nitrogen compression, gas filling, pressure boosting, and industrial gas systems. |
| Oxygen Gas Compressors | Oxygen compression and specialized gas systems where oxygen-compatible materials and components are required. |
| Specialty Gas Compressors | Compression of high-purity, rare, specialty, or process gases where contamination control is important. |
Note: These classifications can overlap. For example, a diaphragm compressor can be both hydraulically actuated and multistage. The final configuration should be selected according to the gas type, inlet pressure, required discharge pressure, flow rate, temperature, and material compatibility.
