The AirTAC Airtac GAF Filter GAF40010AW 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 3/8" ports and a 100 cc drain bowl. It is a filter only — it does not regulate or set pressure.
The GAF40010AW is a genuine AirTAC air filter that spins incoming air to throw liquid water and solid particles into its 100 cc drain bowl, while the 5 um HDPE element traps fine grain. It is a filter only, with no regulator, no pressure gauge and no lubricator, so it cleans the air but never sets or holds a pressure.
This 3/8in model weighs 640 g and its flow curve is plotted to 8000 L/min, placing it in the GAF400 size class that suits medium machine circuits. The automatic drain clears condensate without manual attention, and the included mounting bracket supports the unit firmly on a panel or frame.

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 GAFR400 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 GAFR400-10 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.

Feed a 3/8in line to a CNC machine's solenoid bank, where the 5 um element protects precision valves from fine abrasive dust and the automatic drain handles condensate from rapid cycling.
Mount on a panel feeding a small stamping press, using the 100 cc bowl to collect water between shifts and the included bracket for rigid frame mounting.
Place ahead of a sensitive flow meter or gauge on a test bench, where the 5 um element removes particles that could skew readings and the auto drain keeps the bowl from flooding.
Choose the GAF400 body when your line needs 3/8in or 1/2in ports and a 100 cc drain bowl, stepping up from the GAF300's 60 cc bowl when you want fewer drain interventions. The PC bowl suits general industrial air, while the automatic A drain handles wet or unattended lines without manual checks. The 5 um W element traps finer particles than the standard 40 um for precision valves, and the PT thread matches common local fittings. If you also need a set pressure, use the matching GAFR400-10 filter-regulator instead of a plain filter. The 8000 L/min flow envelope is 1.33x the GAF300's 6000 L/min curve, so this body supports a larger downstream demand.
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 GAFR400-10 filter-regulator as your air-prep needs grow.
The GAF40010AW is a 3/8in air filter with a 5 um HDPE element, a 100 cc PC drain bowl, and a 640 g weight. It operates from 0.15-0.9 MPa (20-130 psi) with a proof pressure of 1.5 MPa (215 psi) and a temperature range of -5 to 70 C. The flow curve is plotted to 8000 L/min, and it uses a PT port thread.
The A code means the GAF40010AW has an automatic drain that expels condensate without manual intervention, ideal for wet lines or unattended operation. This differs from blank drain models, which ship with both semi-auto and manual drains for operator control.
