The AirTAC Airtac GAF Filter GAF30015AJW 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 GAF30015AJW is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 60 cc drain bowl, while the 5 um HDPE element traps fine grain. It has no regulator, no gauge, and no lubricator - it cleans the air but does not control pressure.
This model uses a 1/2in port and weighs 360 g, placing it in the mid-size GAF300 class. The automatic drain clears condensate without manual attention, and the 5 um element suits precision valves or instrument air where finer filtration matters.

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 pick-and-place machine with 5 um filtered air, keeping fine grain out of tight spool clearances.
Protect sensitive pneumatic instruments or gauges downstream by removing water and 5 um particles before they reach calibration-critical components.
Mount on a 1/2in header feeding several cylinders on an assembly station, with the automatic drain handling condensate without operator rounds.
Choose the GAF300 body for 1/4in to 1/2in ports; step up to the GAF400 (100 cc bowl, 8000 L/min curve) for higher flow, or down to the GAF200 (25 cc bowl, 3000 L/min curve) for compact lines. The PC bowl suits general duty, while the automatic drain handles wet or unattended lines without manual checks. This model omits the bracket (J) for panel mounting, uses a 5 um element for finer filtration, and has PT port threads. If you need a set pressure, use the matching GAFR300-15 filter-regulator instead. The 60 cc bowl holds about 2.4x the condensate of the GAF200's 25 cc bowl, meaning fewer drain interventions.
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 filter-only unit with a 5 um HDPE element, rated for 0.15-0.9 MPa (20-130 psi) working pressure and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C. The drain bowl holds 60 cc and the unit weighs 360 g, with a flow curve plotted to 6000 L/min.
The A indicates an automatic drain that expels condensate automatically, ideal for wet lines or unattended operation. This model also has no bracket (J) and a 5 um element (W), with PT port threads.
