Airtac GAF Filter GAF400N15AW
The AirTAC Airtac GAF Filter GAF400N15AW 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 GAF400N15AW
The GAF400N15AW is a genuine AirTAC air filter that spins incoming air to throw liquid water and solid particles into its 100 cc nylon drain bowl, while the 5 um HDPE element traps fine grain. It is a filter only - there is no regulator, pressure gauge, or lubricator built in, so it cleans the air but does not control pressure.
This 1/2in port model weighs 640 g and sits in the GAF400 size class, with its flow curve plotted to 8000 L/min. The automatic drain clears condensate without manual attention, making it well suited for lines where regular draining is inconvenient.

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 GAF400N15AW Is Used
CNC machine tool air prep
Feed a 1/2in line to a CNC spindle or tool changer with 5 um filtered air, protecting precision valves from fine abrasive dust that would shorten their life.
Automated assembly station
Supply a multi-station assembly cell where several cylinders and vacuum generators share one header, using the 100 cc bowl to reduce how often the line is drained.
Instrument air for sensors
Clean air for pneumatic sensors and controllers in a packaging line, where the 5 um element stops particles that could clog tiny orifices and cause false readings.
Is the Airtac GAF Filter GAF400N15AW the Right Filter?
Choose the GAF400 body when your line needs a 3/8in or 1/2in port and a 100 cc drain bowl, stepping up from the GAF300's 60 cc bowl when you want fewer drain interventions. The nylon bowl is a build choice for your environment - confirm compatibility for aggressive surroundings since no temperature or chemical data is printed. This model has the automatic drain (A), the included mounting bracket, and a 5 um element (W) for finer filtration; the PT thread standard must match your existing fittings. If you also need a set pressure, use the matching GAFR400-15 filter-regulator instead of this plain filter. The GAF400's 8000 L/min flow envelope is 1.33x the GAF300's 6000 L/min curve, letting you size up for higher-flow lines.
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 GAF400N15AW FAQ
The GAF400N15AW is a filter-only unit with a 5 um filtering grade, a working pressure range of 0.15-0.9 MPa (20-130 psi), a proof pressure of 1.5 MPa (215 psi), and a temperature range of -5 to 70 C. It has a 100 cc drain bowl and weighs 640 g, with a flow curve plotted to 8000 L/min.
The automatic drain (A) expels condensate from the 100 cc bowl without manual intervention, which is ideal for unattended operation or wet compressed air lines. It replaces the semi-auto and manual drains found on blank models, so you do not need to periodically open a drain valve by hand.
