Airtac GAF Filter GAF400N10
The AirTAC Airtac GAF Filter GAF400N10 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 GAF400N10
The GAF400N10 is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 100 cc nylon drain bowl, while the 40 um HDPE core traps fine grain. It protects downstream valves and cylinders from contamination, but it does not regulate pressure and has no gauge.
This model uses a 3/8in port and weighs 640 g, placing it in the GAF400 size class. The nylon bowl is a build choice for the environment; confirm compatibility for aggressive surroundings. The included bracket supports the weight properly, and the semi-auto plus manual drains give you both automatic condensate release and a manual backup.

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 GAF400N10 Is Used
CNC machine air prep
Feed clean, dry air to a CNC machine's solenoid valves and actuators. The 40 um element and 100 cc bowl handle the condensate load from a typical shop compressor.
Pneumatic test bench
Protect sensitive test fixtures and gauges from water and rust particles. The semi-auto drain releases condensate automatically while the manual drain gives you a quick purge before each test run.
Assembly line tooling
Supply filtered air to multiple air tools on an assembly station. The 3/8in port and 640 g body suit a fixed panel mount, keeping the unit stable and the downstream tools protected.
Is the Airtac GAF Filter GAF400N10 the Right Filter?
Choose the body and port to match your line size and flow needs: GAF400 offers 3/8in and 1/2in ports, sitting between the smaller GAF300 (60 cc bowl, 6000 L/min curve) and the larger GAF500 (108 cc bowl, 9000 L/min curve). The nylon bowl is a material choice with no printed performance difference, so verify it suits your environment. This unit ships with the mounting bracket and a 40 um element; select W for 5 um filtration if you need finer particle removal. The PT thread standard must match your fittings. If you also need a set pressure, use the matching GAFR400-10 filter-regulator instead. The GAF400's 100 cc drain bowl holds about 1.7x the condensate of the GAF300's 60 cc bowl, meaning fewer drain checks between services.
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 GAF400N10 FAQ
It is a 40 um air filter with a 3/8in port. Working pressure range 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 nylon drain bowl holds 100 cc and the unit weighs 640 g. The flow curve is plotted to 8000 L/min.
The N in GAF400N10 indicates a nylon bowl instead of the standard polycarbonate. It is a material choice for the bowl body; AirTAC does not publish temperature or chemical resistance differences, so confirm compatibility for your specific environment. The drain type remains semi-auto plus manual, and the bowl capacity is still 100 cc.
