Compressed Air Separators

Automatic-Drain Compressed Air Separators

A float-operated drain valve on these separators automatically opens when the bowl begins to fill. The first step in water removal, use one of these separators to remove the large amount of water as compressed air cools.

Compressed Air Separators for Oil Removal

In addition to removing large amounts of water, these separators also remove particles and oil droplets. Place them after your compressor and aftercooler, or at the point of use in applications that don't require an aftercooler.

High-Flow Compressed Air Separators

These separators have higher flow rates compared to our other compressed air separators. Prevent equipment damage and wear caused by moisture in your compressed air supply. The first step in water removal, use one of these separators to remove the large amount of water created as compressed air cools.

Compressed Air Condensate Separators

When water is condensed out of a compressed air system, it contains oil from the compressor that makes disposal difficult. These separators use two-stage filtration to reduce oil content to below 20 parts per million.

Process Filtering

Vacuum-Rated Air Separators for Water Removal

Improve vacuum system efficiency and protect components from moisture—these separators remove over 90% of water from air.

Stainless Steel Steam Traps

Also known as thermostatic steam traps, these increase the efficiency of your radiator by venting cool air.

Sanitary Energy-Saving Stainless Steel Steam Traps

When close to steam temperature, these traps—also called thermodynamic steam traps—release condensate from steam lines to save energy in food, pharmaceutical, and other sanitary environments.

Energy-Saving Stainless Steel Steam Traps

Also known as thermodynamic steam traps, these discharge condensate when close to steam temperature for minimal energy loss.

Sanitary Stainless Steel Steam Traps

Suitable for food, pharmaceutical, and other sanitary environments, these steam traps are made of 316 stainless steel with a Viton® fluoroelastomer O-ring to stand up to frequent washdowns with harsh cleaners and sanitizers.

High-Flow Stainless Steel Steam Traps

Also known as inverted-bucket steam traps, these provide near-continuous discharge to accommodate high condensate levels.

High-Flow Iron Steam Traps

Also known as inverted-bucket steam traps, these provide near-continuous discharge to accommodate high condensate levels.

Energy-Saving Iron Steam Traps

Also known as thermostatic steam traps, these vent cool air and condensate to increase energy efficiency in your steam lines.

Brass and Bronze Steam Traps

These steam traps offer good corrosion resistance.

Moisture/Particle Separators

Separators remove 99% of particles from air, gas, and steam lines and have no filter cartridges or baskets to clean and replace.
