The AirTAC Airtac GAF Filter GAF300C15 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 1/2" ports and a 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.
The GAF300C15 is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 60 cc metal drain bowl, while the 40 um HDPE element traps fine grain. It protects downstream valves and cylinders from contamination without regulating pressure.
This 1/2in port model weighs 360 g and sits in the GAF300 size class, with a flow curve plotted to 6000 L/min for sizing. The metal bowl suits demanding environments, and the included bracket supports proper panel mounting rather than relying on tubing.

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 GAFR300-15 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 a CNC machine's solenoid valves and actuators from water and scale in the compressed air line.
Clean the air feeding pneumatic screwdrivers and presses at a workbench, keeping tools cycling reliably.
Filter the supply to a modest multi-fixture line where 1/2in piping distributes air to several stations.
Choose the GAF300 body for 1/4in to 1/2in port lines, with the 1/2in port here suiting medium-flow circuits. The metal bowl is a build choice for tougher surroundings; confirm compatibility for aggressive media. This model ships with both semi-auto and manual drains, the included bracket, a 40 um element, and PT port threads. For finer filtration, select the W option for a 5 um element. If you need pressure control, the matching GAFR300-15 adds a regulator. The GAF300's 60 cc bowl holds 2.4x the condensate of the GAF200's 25 cc, meaning fewer drain checks.
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 GAFR300-15 filter-regulator as your air-prep needs grow.
It is a 40 um air filter with a 60 cc drain bowl and 360 g weight. 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. Port is 1/2in PT thread.
The C code specifies a metal bowl instead of the standard polycarbonate. It is a build choice for more demanding environments, but AirTAC publishes no temperature, chemical, or impact data, so verify compatibility with your specific conditions. This model includes both semi-auto and manual drains.
