The AirTAC Airtac GAF Filter GAF300N15W is a genuine compressed-air filter. Its diversion structure spins the air to separate liquid water and trap solid particles down to 5 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 GAF300N15W is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 60 cc nylon bowl, while the 5 um HDPE element traps fine grain. It protects downstream valves and tools from contamination, but it does not regulate pressure and has no gauge.
This 1/2in-port model weighs 360 g, placing it in the mid-size GAF300 class. Its nylon bowl is a build choice for the environment, and the 5 um element suits precision applications; confirm compatibility for aggressive surroundings.

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.

Feed a bank of precision solenoid valves on a 1/2in manifold with 5 um filtered air, keeping fine particles from sticking spools or orifices.
Protect a CNC machine's pneumatic cylinders and tool changers from water droplets and rust-causing solids in the compressed air line.
Mount at the inlet of a small assembly station header to clean air for multiple air tools and actuators fed from a 1/2in drop.
Choose the GAF300N15W when you need a 1/2in port with a 5 um element and a nylon bowl. The semi-auto plus manual drain lets you empty the 60 cc bowl on schedule or automatically when pressure drops. The included bracket simplifies mounting; the PT thread standard matches common local fittings. If you also need a set pressure, upgrade to the GAFR300-15 filter-regulator instead. The 6000 L/min flow envelope is 2x the GAF200's 3000 L/min, so this body suits larger lines than the 1/8in or 1/4in class.
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.
The GAF300N15W is a filter-only unit with a 5 um HDPE element, a 1/2in port, and a 60 cc nylon drain bowl. It weighs 360 g. Working pressure range 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. It has a semi-auto plus manual drain and includes a mounting bracket.
The N in GAF300N15W indicates a nylon bowl instead of the standard polycarbonate. Nylon is a build material choice for the bowl; the filtering and pressure specs are identical to the PC version. Confirm compatibility with your environment, as no chemical or impact data is published. This model still has the semi-auto plus manual drain.
