Product Overview
The air compressor diaphragm is a key flexible wearing part for the servo cylinder of screw air compressors. It drives valve spool for loading & unloading pneumatic control through rubber deformation and repeated flexing. Under long‑term high‑temperature and oil‑gas environment, the diaphragm will age, harden, crack or tear. Damaged diaphragm causes common faults: failure to load, unstable pressure, internal air leakage, rapid pressure drop after shutdown, high energy consumption and machine alarm. Timely replacement restores the sensitive control of the intake valve, protects the whole intake valve assembly and reduces unplanned downtime loss. This aftermarket replacement matches OEM specification with exact size and hole layout for direct drop‑in installation.
Key Features
✅ Oil-resistant & Anti-aging Premium Rubber Material Made of NBR nitrile rubber or fabric-reinforced composite rubber. Excellent resistance to compressor oil corrosion and continuous high working temperature. Great anti-fatigue and tear-resistant performance. Resists hardening and cracking after millions of flex cycles, ideal for 24-hour heavy-duty industrial operation and longer service life.
✅ Precision Moulding & Superior Sealing Performance One-piece moulding ensures high flatness and precise flange holes. Uniform deformation and stable rebound prevent control air leakage. It guarantees fast load-unload response, fixes pressure fluctuation and slow pressure build-up, and cuts unnecessary energy consumption.
✅ OEM Direct-fit Design, Time-saving Maintenance Fully copies original dimension. No trimming or secondary modification required. Quick installation greatly shortens equipment downtime and reduces on-site maintenance labor cost.
✅ Smooth Operation & Full Valve Protection Soft and steady elastic driving force cushions impact inside servo cylinder. Prevent valve jamming caused by broken rubber fragments, protecting internal piston, springs and other components to extend the whole intake valve service life.
Application
Compatible with intake valve servo cylinders of mainstream screw air compressor brands including Ingersoll Rand, Hoerbiger, Fusheng. Widely used in factories, mining sites, auto repair shops and manufacturing production lines. It is essential consumable spare part for compressor routine maintenance.
