Benefits

• Restores proper compressor loading and unloading
• Improves energy efficiency by preventing unnecessary compression
• Ensures stable compressed air output
• Reduces air leakage and pressure loss
• Extends the service life of the inlet valve and air end
• Minimizes maintenance costs and unplanned downtime

Working Process

1. At startup, the unloader keeps the compressor in the unloaded state.
2. When air demand increases, the inlet valve opens to allow air into the air end.
3. As system pressure reaches the preset value, the unloader closes or modulates the inlet valve to stop unnecessary compression.
4. The rebuilt valve ensures smooth load/unload cycling, stable pressure control, and efficient compressor operation.

Typical Applications

• Atlas Copco oil-injected rotary screw air compressors
• Compatible with selected GA series compressors, including applications such as the GAe26-10P (verify by model and serial number)
