Applications & Benefits
This GRACO model is built for industrial compressed-air lines where contamination (water, oil, particles) must be removed to protect downstream equipment such as regulators, lubricators, and pneumatic actuators. The 40-micron element is a good balance of particle removal without excessive pressure drop in moderate duty air supply systems. The auto drain assists in removal of condensate without manual intervention, improving uptime and reducing maintenance overhead.
Installation Tips
Maintenance & Parts Notes
The OEM manual lists replacement filter elements and sight glass kits for the 106148 model:
- Filter element kit for 3/8″ port, 40 micron: part no. 106206.
- Sight-glass kit: part no. 104991.
Why Consider This Model?
If you’re selling air-prep accessories in your industrial/construction catalog, this model hits a nice niche: 3/8″ NPT is a common size for smaller supply lines, 250 PSI rating covers many systems, and the auto-drain feature adds real value for buyer ROI (less manual draining). Good fit for mid-sized air tools or equipment setups.
Limitations to Note
The filter element is 40 micron, which means fine particles (<40 µm) will pass through; if your application demands very fine filtration (e.g., for critical pneumatic tooling or clean room), you may need a finer-mesh element or additional downstream filter stage. Also, ensure ambient/line temperature stays within ~4-65 °C (40-150 °F) range.
