The AirTAC Airtac GAF Filter GAF300N15JW 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 GAF300N15JW is a genuine AirTAC air filter that spins incoming air to throw liquid water and solid particles into its 60 cc drain bowl, while the 5 um HDPE core traps fine grain. This 1/2in-port unit weighs 360 g and is built for the 300 size class, with a nylon bowl and no mounting bracket.
This filter-only device has no regulator, no pressure gauge and no lubricator - it cleans the air but does not control pressure. With a 5 um element it suits precision valves or instrument air, and the semi-auto plus manual drain gives you both automatic condensate release and a manual backup for servicing.

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 pneumatic valves on a small assembly machine. The 5 um element stops fine grain that could clog valve pilots, while the 60 cc bowl handles typical shift-long condensate.
Protect sensitive instruments or gauges on a test bench. The 5 um HDPE core removes water and solids before they reach the instrument, and the semi-auto drain keeps the bowl from overflowing during long runs.
Supply a single-station pneumatic press or a dedicated work cell. The 1/2in port and 360 g body fit neatly into a compact line, and the curve to 6000 L/min gives ample envelope for one or two actuators.
Choose the GAF300N15JW when you need a 1/2in-port filter in the 300 size class, which is a step up from the GAF200's 1/4in port and 25 cc bowl, and a step down from the GAF400's 3/8in-1/2in ports and 100 cc bowl. The nylon bowl is a build choice - confirm compatibility for aggressive surroundings since no chemical data is printed. The J code means no bracket is included, so plan for panel mounting or an existing bracket. The 5 um element traps far finer particles than the standard 40 um, at the cost of more frequent element service. The PT thread standard must match your fittings. If you also need a set pressure, use the matching GAFR300-15 filter-regulator instead. The GAF300's 60 cc drain bowl holds 2.4x the condensate of the GAF200's 25 cc bowl.
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 GAF300N15JW is a filter-only unit with a 5 um filtering grade, a working pressure range of 0.15-0.9 MPa (20-130 psi), a proof pressure of 1.5 MPa (215 psi), and a temperature range of -5 to 70 C. It has a 60 cc drain bowl and weighs 360 g, with a flow curve plotted to 6000 L/min.
The J code means the mounting bracket is NOT included with the GAF300N15JW. You will need to provide your own panel mount or use an existing bracket. The filter itself has a nylon bowl, a 5 um element, and a semi-auto plus manual drain.
