The AirTAC Airtac GAF Filter GAF300C10AJ 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.
The GAF300C10AJ is a genuine AirTAC air filter that removes water and solid particles from compressed air lines using a diversion structure that spins the air to throw contaminants into the drain bowl. This model has a 3/8in port, a 40 um HDPE filter core, and a 60 cc metal bowl, weighing 360 g.
This filter-only unit does not regulate pressure and has no gauge. The metal bowl is a build choice for demanding environments; confirm compatibility for aggressive surroundings. The automatic drain clears 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.

A GAF has no regulator and no pressure gauge — there is no type, gauge or reflux code. Need to regulate pressure too? The matching GAFR300-10 is the same filter with a built-in 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.

Protect precision valves and cylinders on a CNC machine from water and particulates. The automatic drain keeps the 60 cc bowl from filling during long, unattended machining runs.
Feed clean air to pneumatic actuators on an assembly line. The 3/8in port matches typical station manifolds, and the metal bowl resists impacts in busy production areas.
Guard air-operated packaging machinery from condensate and dirt. The 40 um element handles general plant air, while the automatic drain reduces maintenance checks on high-cycling equipment.
Choose the GAF300 body for 1/4in to 1/2in port lines where a 60 cc drain bowl and 360 g weight suit the installation. This model has a metal bowl, automatic drain, no bracket, and a 40 um element with PT threads. For a set pressure, use the matching GAFR300-10 filter-regulator instead. The 6000 L/min flow envelope is 2x the GAF200's 3000 L/min curve, showing this body's larger capacity for medium-flow systems.
Quick checklist
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.
The GAF300C10AJ is a filter only with a 40 um HDPE element, 3/8in PT port, and 60 cc metal drain bowl. Working pressure is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), and temperature range is -5 to 70 C. The unit weighs 360 g and has a flow curve plotted to 6000 L/min.
The 'A' code means this GAF300 has an automatic drain that expels accumulated condensate without manual operation. This is ideal for wet air lines or installations where regular manual draining is impractical. The metal bowl (C) is a durable build option, but confirm material compatibility for your specific environment.
