Vacuum-Rated Air-Intake Filters
Typically used on vacuum pumps, these filters ensure that clean air is going in and coming out of your system. Install them on the inlet to stop dust from entering your equipment.
Replacement elements are sold separately. HEPA elements have greater efficiency for high-purity applications, but they reduce the maximum flow rate of your filter. Polyester and fiberglass are more durable than paper.

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.

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. Typically used with vacuum pumps, they minimize vacuum pressure drop, even when the element is saturated with water. Separators have a viewing window so you can see inside to monitor water removal. Mount separator vertically for proper drainage (brackets sold separately), and install before air filters.

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.

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.

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.
