Airtac GAF Filter GAF40015AJW
The AirTAC Airtac GAF Filter GAF40015AJW 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 100 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF40015AJW
The GAF40015AJW is a genuine AirTAC air filter that removes liquid water and solid particles from compressed air lines using a diversion structure that spins the air before the HDPE element traps fine grain. It is a filter only, with no regulator or pressure gauge, and it does not control pressure.
This model has a 1/2in port, a 5 um filter element, and a 100 cc drain bowl. The automatic drain (A) releases condensate without manual intervention, and the J code means the mounting bracket is not included. The unit weighs 640 g, placing it in the mid-size class for machine-level filtration.

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.

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 GAF40015AJW Is Used
CNC machine air circuits
Feeds a 1/2in line supplying air to a CNC machine's tool changer and work-holding valves, where the 5 um element protects precision spool valves from fine abrasive dust.
Automated assembly stations
Protects a multi-valve manifold on an automated assembly station, with the automatic drain handling condensate from a wet compressor line without daily manual checks.
Packaging line pneumatics
Serves a packaging machine's cylinder bank, with the 100 cc bowl and 8000 L/min envelope supporting intermittent high-flow actuator movements while keeping water out.
Is the Airtac GAF Filter GAF40015AJW the Right Filter?
Choose the GAF400 for 3/8in to 1/2in lines where you need 100 cc of condensate capacity and a flow envelope plotted to 8000 L/min. The 5 um element (W) traps finer particles than the standard 40 um for precision valves, while the automatic drain (A) suits unattended operation. The J code omits the bracket for panel mounting, and the PT thread standard matches common local fittings. If you also need pressure control, use the matching GAFR400-15 filter-regulator instead. The 100 cc bowl holds about 1.67x the condensate of the GAF300's 60 cc bowl, so you can run longer between drain checks.
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 GAF40015AJW FAQ
The GAF40015AJW is a filter only, with a 5 um HDPE element, a 1/2in PT port, and a 100 cc drain bowl. Working pressure is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -5 to 70 C, and it weighs 640 g. The flow curve is plotted to 8000 L/min.
The A means the filter has an automatic drain that expels condensate automatically, ideal for wet or unattended lines. The J means the mounting bracket is not included, so you must use a panel mount or an existing bracket. This model has a PC bowl and a 5 um element.
