The AirTAC Airtac GAF Filter GAF30010AJ 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 GAF30010AJ 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 HDPE core traps fine grain. It cleans the air but does not regulate pressure and has no gauge.
This model has a 3/8" port, a 40 um filter element, and an automatic drain, with a PC bowl and no mounting bracket. Its 360 g mass and 6000 L/min flow envelope place it in the mid-size class, suited for protecting a single valve or small machine station.

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 a precision valve or small cylinder on a CNC machine from water and grit carried in the shop air supply.
Feed a single pneumatic test fixture or calibration station with clean, dry air before it reaches sensitive instruments.
Guard a film-sealing or carton-erecting station where a 3/8in line supplies one or two actuators.
Choose the GAF300 body for 1/4" to 1/2" lines; step up to a GAF400 (100 cc bowl, 8000 L/min curve) for heavier demand, or down to a GAF200 (25 cc bowl, 3000 L/min curve) for compact jigs. The PC bowl suits general dry indoor use, while the automatic drain handles wet or unattended lines without manual checks. This unit omits the bracket (J) for panel mounting, and the PT thread matches standard local fittings. If you also need a set pressure, use the matching GAFR300-10 filter-regulator instead. The 60 cc bowl holds about 2.4x the condensate of a GAF200's 25 cc bowl, so you drain it less often.
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.
It is a 40 um air filter with a 3/8" port, a 60 cc drain bowl, and a 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. The flow curve is plotted to 6000 L/min.
The A code means an automatic drain that expels collected condensate without manual intervention, ideal for wet lines or unattended operation. This model has no bracket (J), so plan for a panel mount or an existing bracket.
