High-Vacuum Inline Filters
Capture oil, oil vapor, and other contaminants from your pump to prevent them from spreading into your high-vacuum system with these filters. When it's time to replace the filter element, you don't need tools to access it; undo the quick-release clamp to open the filter body. Filters have a drain port to remove collected oil.
Filters with quick-clamp connections (also known as KF, NW, and QF fittings) require a quick clamp and a ring (both sold separately) for each connection.
Filters with claw-clamp connections (also known as ISO-K fittings) will connect to larger components than filters with quick-clamp connections. Use four claw clamps and a ring (all sold separately) to secure each connection. Double-claw clamps attach to the grooves on the fittings. Single-claw clamps have a clamp on one end and an exposed bolt on the other. Thread the bolt-end directly into the body of pumps, valves, or other high-vacuum components.

High-Vacuum Air-Intake Filters
Install these filters between your high-vacuum chamber and the inlet of your pump to remove dust, water vapor, and other contaminants from the system and protect the pump. Commonly used in vacuum-furnace and coating applications, they have a polyester filter element that traps particles as small as 5 microns. All filters have been helium-leak tested to ensure quality. When the filter element becomes clogged, you can replace it.
Quick-clamp connections are also known as KF, QF, and NW connections; they require a ring and quick clamp (sold separately) to complete the connection.
Claw-clamp connections are also known as ISO-K connections; use a ring and multiple claw clamps (sold separately) to secure. Double-claw clamps attach to the grooves on the fittings. Single-claw clamps have a clamp on one end and an exposed bolt on the other. Thread the bolt-end directly into the body of pumps, valves, or other high-vacuum components.

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.

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.

Exhaust Filters/Mufflers for Dry High-Vacuum Pumps
Purify exhaust fumes while silencing the noise from your oil-free high-vacuum pumps. With quick-clamp (KF) connections, these filters/mufflers connect to exhaust ports with a clamp and ring (sold separately). Mount them vertically or horizontally. All are carbon steel with a powder-coated finish for corrosion resistance.
