Airtac GAF Filter GAF40015
The AirTAC Airtac GAF Filter GAF40015 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 1/2" ports and a 100 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF40015
The GAF40015 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 HDPE core traps fine grain. It is a filter only, with no regulator, no pressure gauge, and no lubricator.
This 1/2in model uses a 40 um filter element and a clear PC bowl. Its 640 g body places it in the mid-size class, a step up from the 360 g GAF300, so it suits lines feeding several valves or a 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 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 GAFR400-15 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.

Where the Airtac GAF Filter GAF40015 Is Used
Machine tool air prep
Protect the solenoid valves and air cylinders on a CNC lathe or milling machine from condensed water and scale.
Small assembly station
Feed a multi-fixture workbench where several pneumatic screwdrivers or presses share one 1/2in supply line.
Paint booth air supply
Remove water droplets and particulates from the air feeding spray equipment, helping to prevent surface defects.
Is the Airtac GAF Filter GAF40015 the Right Filter?
Choose the GAF40015 when your line needs 1/2in ports and the 100 cc drain bowl that this body offers. The PC bowl is the standard build choice; confirm compatibility for aggressive surroundings. The semi-auto and manual drains are both fitted, so you can purge automatically or by hand. The mounting bracket is included, and the 40 um element covers general-purpose filtration. Ports are PT thread. If you also need a set pressure, use the matching GAFR400-15 filter-regulator instead. The 8000 L/min flow envelope is 1.33x the 6000 L/min of the GAF300, giving you a clear sizing step between the two bodies.
Quick checklist
- ✓ Body size for your peak flow (1/2" here)
- ✓ Element 40 µm (general) or 5 µm (fine)
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Bracket kept or removed (J)
- ✓ Need pressure control too? Use GAFR400
Installation & Maintenance Notes
- check Install with the airflow arrow: IN to OUT, bowl accessible.
- check Place the filter FIRST in the air-prep train, ahead of any regulator or lubricator.
- check Keep pressure at or below the 1.5 MPa (215 psi) proof limit.
- check Drain condensate before the 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 640 g unit on its bracket, not on the tubing.
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 GAFR400-15 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF40015 FAQ
The GAF40015 is a 40 um air filter with a 1/2in PT port. Its working pressure range is 0.15-0.9 MPa (20-130 psi), with a proof pressure of 1.5 MPa (215 psi). The temperature range is -5 to 70 C. It has a 100 cc drain bowl and weighs 640 g.
This model includes both a semi-auto drain and a manual drain. The semi-auto drain purges condensate automatically when pressure is released, while the manual drain lets you empty the bowl on demand. This gives you flexibility in how you manage the collected water and solids.
