Air Filter Regulator

Extend the Life of Pneumatic Instrumentation

Small Investment, Significant Results

Using a filter regulator with pneumatically actuated valves is a small investment that can significantly extend the life of pneumatic instrumentation.

 The primary function of the regulator is to provide the instrument with a supply of stable air pressure. It also prevents the actuator from over-pressurizing by limiting how much pressure you’ll be able to deliver through your positioner. This is important because your actuator will malfunction if it over-pressurizes.

The next thing that makes the filter regulator a good option is that it helps prevent water and debris from getting into the small air passages in the instrument.

Many people in the process industry assume that their instrument air supply system delivers clean, dry air. But, unfortunately, that’s not the case. The number one cause of premature instrument failure is poor air quality.

Make a small investment of time and periodically drain any water that may have accumulated in the dripwell by simply opening the drain valve and allowing any water to drain out. Remember to close the valve.

Also, check the filter every time you do maintenance or calibration on your instrument and replace the filter if need be.  You’ll save time and money in the long run.
