Oil-Mist-Eliminating Exhaust Filters
Stop oil mist and smoke from exiting your equipment and into your environment. These exhaust filters are commonly used with small oil-sealed vacuum pumps. Install them on the outlet.
Filters with nickel-plated steel housing have better corrosion resistance than filters with a steel housing.

High-Vacuum Oil-Mist-Eliminating Exhaust Filters
Clamp these exhaust filters onto oil-sealed, high-vacuum pumps to remove oil, smoke, and other contaminants and keep workplace air clean. Once captured, the oil returns to the pump to be reused. Instead of a threaded connection, these filters have a quick-clamp high-vacuum fitting, which is commonly found on high-vacuum pumps. Quick-clamp high-vacuum fittings are also known as KF, QF, and NW fittings; they require a ring and clamp (sold separately) to complete the connection.

Odor-Absorbing High-Vacuum Oil-Mist-Eliminating Exhaust Filters
To keep airborne oil and odor out of your work environment, connect these filters to your high-vacuum oil pump. They purify pump exhaust in two stages: a fiberglass layer captures oil and collects it into a drain, and an active carbon layer removes any odor-causing oil or chemical vapors. Attach the quick-clamp fitting on the filter inlet to your high-vacuum pump. Use a ring and clamp (sold separately) to complete the connection.

Oil-Mist-Eliminating Mufflers
In addition to a filter, these mufflers have a wool felt disc to trap oil mist. They are often used with vacuum pumps and suction devices to reduce noise and filter exhaust fumes.
