Keep water and particles out of the air line before they reach your tools. The products in this collection combine air filtration with pressure regulation, giving a compact point-of-use solution for workshops and pneumatic equipment. Current options include 5-micron filter-regulators in 1/4 in and 3/8 in NPT configurations.
Before you buy: match the port size, flow requirement, drain style, and filtration specification to the work being done. A filter-regulator is a practical choice for many pneumatic tools; applications that require exceptionally dry air may need additional system treatment beyond a point-of-use water separator.
Compressed-air filter selection guide
What a point-of-use air filter does
Compressed-air filters and water separators help remove entrained water and solid contamination from a line. This helps protect pneumatic tools and supports more consistent air delivery.
How to choose
- Check the filtration rating against the tool or process requirement.
- Choose a flow capacity that exceeds the expected working demand.
- Match the inlet and outlet ports to the installation.
- Select a drain style that the team will actually maintain.
- For paint, instrumentation, food, breathing-air, or other critical applications, verify the complete air-quality requirement and use the appropriate dedicated treatment equipment.
Air filter FAQ
Is a water separator the same as an air dryer?
No. A point-of-use water separator or filter removes liquid water and particles from the air stream. A dryer addresses moisture in a different way and may be required where a specified dew point or very dry air is needed.
When should I drain the filter bowl?
Follow the product instructions and inspect manual-drain bowls regularly. The right schedule depends on compressor run time, humidity, and condensate load.
