Airtac GAF Filter GAF30015
The AirTAC Airtac GAF Filter GAF30015 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 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF30015
The AirTAC GAF30015 is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 60 cc drain bowl, while the HDPE element traps fine grain. It is not a regulator and has no pressure gauge, so it cleans your air without attempting to control its pressure.
This model uses a 1/2in port and a 40 um filter element, with both semi-auto and manual drains fitted. Weighing 360 g, it belongs to the GAF300 size class, which is a step up from the GAF200's 25 cc bowl and a step down from the GAF400's 100 cc bowl.

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.

Where the Airtac GAF Filter GAF30015 Is Used
CNC coolant lines
Protect a CNC machine's solenoid valves from water and rust particles carried in the shop air supply, keeping cycle times consistent.
Packaging line pneumatics
Guard the cylinders on a carton-sealing station, where a 1/2in port matches the line's main feed and the 60 cc bowl handles a shift's condensate.
Assembly bench manifolds
Feed a small manifold that runs several hand tools or fixtures, with the semi-auto drain clearing water whenever the line is pressurized.
Is the Airtac GAF Filter GAF30015 the Right Filter?
Choose the GAF300 body when you need a 1/2in port and a 60 cc condensate bowl, which suits a single machine or a small branch line. The PC bowl is the standard build, while the semi-auto plus manual drain lets you empty the bowl automatically when pressurized or manually when needed. The included mounting bracket simplifies installation, and the 40 um element handles general workshop air. If you need to set a pressure downstream, pair this filter with a GAR regulator or step up to the GAFR300-15 filter-regulator. The GAF300's flow envelope plotted to 6000 L/min is twice the GAF200's 3000 L/min curve, so you can size up with confidence.
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 GAFR300
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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 360 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 GAFR300-15 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF30015 FAQ
It is a 40 um air filter with a 1/2in port, a 60 cc drain bowl, and a weight of 360 g. The 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, and the flow curve is plotted to 6000 L/min.
The semi-auto drain expels collected condensate automatically when the air supply is turned off, while the manual drain lets you empty the bowl on demand with a simple twist. This gives you both hands-free operation and a backup method for scheduled maintenance.
