Draper Combined Filter/Regulator Unit - 1/2" BSP

The filter has a rating of 40 microns.

The maximum inlet pressure is 10 bar (145 psi).

You can use the manual or semi-automatic drain valve located at the bottom of the transparent bowl. For manual draining, open the valve fully until water is expelled, then close it. For semi-automatic, you may need to slightly reduce the air pressure.

Yes, the screw-on polycarbonate bowl is designed to be removed for cleaning and can be replaced if damaged.

This unit features a 1/2" BSP thread size for connection.

You can connect it to a higher pressure compressor, but the inlet pressure must not exceed the unit's maximum rating of 10 bar (145 psi). The regulator will then reduce the pressure downstream.

The frequency depends on the quality of your compressed air. It is recommended to inspect the filter regularly and clean or replace it when visibly dirty or if performance is affected.

Check that the regulator knob is not fully tightened or loosened. Ensure the inlet pressure is within the specified range (max 10 bar). Inspect the filter for blockage, which can affect regulation.

Ensure the drain valve is fully closed after emptying. Check the filter element for damage or excessive clogging. Verify that the inlet air is not excessively saturated with moisture, and consider additional air drying solutions if necessary.

Confirm that your existing fittings are 1/2" BSP. Ensure any thread sealant is applied correctly and not obstructing the connection. Check for damaged threads on either the unit or the fitting.

Inspect all connection points for proper sealing. Check the O-ring or seal between the bowl and the housing for damage and ensure it is correctly seated. Verify the drain valve is fully closed and sealed.
