Airtac GAF Filter GAF400N10A
The AirTAC Airtac GAF Filter GAF400N10A 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 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 GAF400N10A
The GAF400N10A is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 100 cc nylon bowl, while the HDPE element traps fine grain. It cleans the air but does not regulate pressure, so there is no gauge or adjusting knob on this body.
This 3/8" model ships with a 40 um element and an automatic drain that clears condensate by itself. At 640 g it belongs to the GAF400 size class, which needs a proper panel or frame mount rather than support from the tubing alone.

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 GAF400N10A Is Used
CNC spindle air
Feed a clean 3/8" air supply to a CNC spindle or tool changer, where the automatic drain keeps condensate from reaching precision bearings.
Machine header feed
Protect a small machine header feeding several valves and cylinders, using the 100 cc bowl to reduce drain checks across a shift.
Instrument air prep
Prepare air for gauges or sensors downstream, with the 40 um element stopping dirt that could clog fine orifices.
Is the Airtac GAF Filter GAF400N10A the Right Filter?
Choose the GAF400 body when a 3/8" port with a 100 cc drain bowl fits your line; step down to the GAF300 for a lighter 360 g unit with a 60 cc bowl, or up to the GAF500 for a 3/4" port and 108 cc bowl. The nylon bowl is a build choice, and the automatic drain suits wet or unattended lines while the included bracket simplifies mounting. For pressure control, pair this filter with a separate GAR regulator or use the matching GAFR400-10 filter-regulator instead. The GAF400's 8000 L/min flow envelope is 1.33x the GAF300's 6000 L/min curve, so you can size up for higher-demand lines.
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 GAF400N10A FAQ
The GAF400N10A is a 3/8" port air filter with a 40 um HDPE element, a 100 cc drain bowl, and a 640 g weight. 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. It has an automatic drain and a nylon bowl.
The A code means this GAF400 has an automatic drain that expels collected condensate without manual intervention. This is ideal for wet lines or unattended operation, unlike the blank drain option which includes both semi-auto and manual drains.
