Airtac GAF Filter GAF400C10AJW
The AirTAC Airtac GAF Filter GAF400C10AJW 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 GAF400C10AJW
The GAF400C10AJW 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 core traps fine grain. It has no regulator, no gauge, and no lubricator - it cleans the air but does not control pressure.
This 3/8in model weighs 640 g and uses a metal bowl with an automatic drain, making it a sturdy choice for a machine header. Its flow curve is plotted to 8000 L/min, so it suits a mid-size line where a GAF300 at 6000 L/min would be undersized.

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 GAF400C10AJW Is Used
CNC coolant lines
Protect a precision valve manifold on a CNC machine from water carryover and fine swarf, with the 5 um element and automatic drain running unattended through a shift.
Assembly station header
Feed a multi-station assembly bench with clean air at 3/8in, using the 100 cc bowl to cut drain checks compared to a smaller filter on the same line.
Instrument air pre-filter
Place this filter ahead of a sensitive pressure sensor or flow meter, where the 5 um element stops fine grain that could skew readings or wear internals.
Is the Airtac GAF Filter GAF400C10AJW the Right Filter?
Choose the GAF400 body for 3/8in or 1/2in ports where you need a 100 cc bowl and an 8000 L/min envelope; step down to a GAF300 for lighter 60 cc duty or up to a GAF500 for a 3/4in port. The metal bowl here suits demanding environments, while the automatic drain handles wet lines without manual attention, and the J code means no bracket is included. The 5 um element traps finer particles than the standard 40 um for precision valves, and the PT thread matches common local fittings. If you also need a set pressure, use the matching GAFR400-10 filter-regulator instead. The 100 cc bowl holds about 1.67x the condensate of a GAF300's 60 cc bowl, so you drain less often.
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 GAF400C10AJW FAQ
It is a filter-only unit with a 5 um HDPE element, rated for 0.15-0.9 MPa (20-130 psi) working pressure and 1.5 MPa (215 psi) proof pressure. Temperature range is -5 to 70 C, the drain bowl holds 100 cc, and the unit weighs 640 g. The flow curve is plotted to 8000 L/min.
The C code specifies a metal bowl, chosen for demanding environments where impact or chemical resistance matters - confirm compatibility for your specific surroundings. The A code means an automatic drain, so condensate is expelled without manual intervention, ideal for wet or unattended lines. This model also has no bracket (J), so plan for a panel mount or existing support.
