Airtac GAF Filter GAF400C10W
The AirTAC Airtac GAF Filter GAF400C10W 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.

About the Airtac GAF Filter GAF400C10W
The GAF400C10W is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 100 cc metal drain bowl, while the 5 um HDPE element traps fine grain. It cleans the air for downstream components; it does not regulate pressure and carries no gauge.
This 3/8in model weighs 640 g and uses a metal bowl, making it a sturdy mid-size choice for protecting valves and cylinders. The semi-auto and manual drains are both fitted, so you can either let the float open automatically or purge the bowl by hand.

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.

Where the Airtac GAF Filter GAF400C10W Is Used
CNC spindle air
Feed a 3/8in line to a CNC spindle or tool changer where 5 um filtration protects precision bearings from abrasive dust.
Pneumatic press
Mount on a stamping or assembly press to strip water and scale from the air before it reaches the main control valve.
Packaging line
Use on a packaging machine's actuator bank, where the 100 cc bowl reduces how often an operator must drain condensate.
Is the Airtac GAF Filter GAF400C10W the Right Filter?
Choose the GAF400 body when 3/8in or 1/2in ports match your line; it sits above the GAF300 (60 cc bowl, 360 g) and below the GAF500 (108 cc bowl, 680 g). The metal bowl suits demanding environments, while the 5 um element traps finer particles than the standard 40 um at the cost of more frequent service. The included bracket simplifies mounting, and the PT thread standard must match your fittings. If you also need a set pressure, step up to the matching GAFR400-10 filter-regulator instead. The GAF400's 100 cc drain bowl holds about 1.67x the condensate of the GAF300's 60 cc bowl, meaning fewer manual drain checks.
Quick checklist
- ✓ Body size for your peak flow (3/8" 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 GAFR400-10 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF400C10W FAQ
It is a filter-only unit with a 5 um HDPE element, a 3/8in PT port, and a 100 cc metal drain bowl. Working pressure is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), and temperature range is -5 to 70 C. The unit weighs 640 g and its flow curve is plotted to 8000 L/min.
The C code specifies a metal bowl, which is a build choice for environments where you prefer added robustness over the standard PC or nylon options. AirTAC does not publish temperature, chemical, or impact data for bowl materials, so confirm compatibility with your specific surroundings before ordering.
