Compressed Air Line Filter & Oil-Water Separator

Product Description

Compressed air from a screw compressor typically contains oil aerosol (2–5 mg/m³), solid particles from the intake, and moisture. Filters installed in the airline progressively clean the air to the required quality level.

A typical installation uses a pre-filter (3 or 1 micron) to catch bulk particles and liquid, followed by a fine filter (0.01 micron) to remove oil aerosol, and optionally an activated carbon filter to adsorb oil vapor down to 0.003 mg/m³.

The condensate collected by dryers, filters, and receiver tanks is a mixture of water and compressor oil. Regulations in most countries prohibit draining this directly to sewer. An oil-water separator uses adsorption media or polypropylene membranes to separate the oil, producing clean water that can be discharged.

Differential Pressure Gauge

Each filter housing includes a gauge showing the pressure drop across the element. When the reading exceeds the limit, it is time to replace the element.

Auto Drain on Each Filter

Every filter housing has a float-type auto drain to remove collected liquid continuously, preventing it from re-entering the air stream.

Environmental Compliance

The oil-water separator reduces oil content in discharged condensate to below 15 mg/L, meeting discharge regulations in most jurisdictions.
