Head Unloader Option – Simple & Clear
This pump is available with an optional Head Unloader configuration, depending on how your system is designed to operate.
No Head Unloaders (Standard)
- Compressor shuts off at full pressure
- Restarts when air is needed
- Best for most standard applications
Yes – Head Unloaders (Optional Upgrade)
- Pump continues running at full pressure in an unloaded state
- Motor stays running instead of starting and stopping
- Helps reduce electrical strain and wear on components
- Ideal for high-demand or frequent cycling applications
⚠️ Important
Head unloaders are designed for systems that operate in continuous (unloaded) mode.
If your compressor currently runs start/stop, additional controls or modifications may be required.
Ideal Applications
- Automotive & heavy-duty truck repair facilities
- Medium to large woodworking operations
- Manufacturing and production environments
- Agricultural and grain handling operations
