Airtac GAF Filter GAF300C10A
The AirTAC Airtac GAF Filter GAF300C10A is a genuine compressed-air filter. Its diversion structure spins the air to separate liquid water and trap solid particles down to 40 µm, protecting downstream valves and tools. It has 3/8" ports and a 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF300C10A
The GAF300C10A is a genuine AirTAC air filter that removes liquid water and solid particles from compressed air lines using a diversion structure that spins the air before it passes through the 40 um HDPE filter core. This is a filter only, with no pressure regulation or gauge, and it does not lubricate the air.
This model has a 3/8in port, a 60 cc metal drain bowl, and weighs 360 g, placing it in the mid-size GAF300 class. The automatic drain expels condensate without manual intervention, making it suitable for wet or unattended lines.

Specifications follow the official AirTAC GAF catalogue (pages 225-226). Air must not freeze in the unit. This is a filter only — it separates water and solid particles but does not set or hold a downstream pressure. To regulate pressure as well, use the matching GAFR300 filter-regulator.

Figures are the end of the flow curve plotted in the AirTAC catalogue — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. A filter this size drops less pressure at flow than the same-body GAFR filter-regulator, so match it to your peak demand.

Where the Airtac GAF Filter GAF300C10A Is Used
CNC Machine Tooling
Protect precision pneumatic actuators and tool changers on CNC machines from water and particulate contamination, ensuring consistent operation and reducing wear on sensitive components.
Assembly Line Pneumatics
Supply clean air to pneumatic valves and cylinders on an assembly line, filtering out condensate and scale that could cause sticking or premature seal failure in critical production equipment.
Packaging Equipment
Guard air-operated packaging machinery, such as film sealers and case erectors, against water and dirt ingress, helping maintain reliable cycle times and protecting downstream components.
Is the Airtac GAF Filter GAF300C10A the Right Filter?
Choose the GAF300 body for 1/4in to 1/2in port applications that need a 60 cc drain bowl and a 6000 L/min flow envelope. The metal bowl (C) is a build choice for demanding environments, though no specific temperature or chemical compatibility data is printed, so confirm it suits your surroundings. The automatic drain (A) handles condensate removal automatically, unlike the semi-auto+manual drain on blank models. The included mounting bracket provides secure installation; the 40 um element is the general-purpose grade, while a 5 um element (W) is available for finer filtration. This unit uses PT port threads, with G and NPT options available. The 1.5 MPa proof pressure provides a 1.67x margin over the 0.9 MPa working maximum, though it is a burst-test rating, not a working pressure.
Quick checklist
- ✓ Body size for your peak flow (3/8" here)
- ✓ Element 40 µm (general) or 5 µm (fine)
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Bracket kept or removed (J)
- ✓ Need pressure control too? Use GAFR300
Installation & Maintenance Notes
- check Install with the airflow arrow: IN to OUT, bowl accessible.
- check Place the filter FIRST in the air-prep train, ahead of any regulator or lubricator.
- check Keep pressure at or below the 1.5 MPa (215 psi) proof limit.
- check Drain condensate before the 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 360 g unit on its bracket, not on the tubing.
This is a filter only — it removes water and solid particles but adds no pressure control and no lubrication. Add a GAR regulator, a GAL lubricator, or step up to the GAFR300-10 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF300C10A FAQ
The GAF300C10A is a filter-only unit with a 40 um HDPE element, a 3/8in PT port, and a 60 cc metal drain bowl. It weighs 360 g and has a flow curve plotted to 6000 L/min. The working pressure range is 0.15-0.9 MPa (20-130 psi), with a proof pressure of 1.5 MPa (215 psi). The operating temperature range is -5 to 70 C, and it must not freeze.
The automatic drain (A) on this model expels accumulated condensate from the 60 cc bowl without manual intervention, making it ideal for wet or unattended lines. This is different from models with a blank drain code, which include both semi-auto and manual drain options. The automatic drain ensures consistent water removal, protecting downstream equipment from liquid carryover.
