Where It's Used
Applications & Industries
General plant air

Workshop tools, pneumatics and valve actuators. First protection in the compressed-air line.

Compressed Air hub →
Upstream of dryers

Removes bulk water and oil before desiccant or refrigeration dryers, protecting the bed.

Pre-stage for fine filters

Absorbs bulk load so MF and SMF elements work on fine contamination only — extends service life.

Food & beverage

First stage before sterile P-SRF elements in food and beverage compressed-air trains.

F&B hub →
Pre-dryer protection

Protects desiccant bed from oil and water load that would reduce drying capacity.
