Airtac GAF Filter GAF300N10A
The AirTAC Airtac GAF Filter GAF300N10A 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 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF300N10A
The GAF300N10A is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 60 cc nylon bowl, while the HDPE core traps fine grain. It has no regulator, no gauge, and no lubricator; it cleans the air but does not control pressure. This model uses a 3/8" port, a 40 um element, and an automatic drain.
With a 360 g mass, this GAF300 sits in the mid-size class, a step up from the 200 g GAF200 and below the 640 g GAF400. The nylon bowl is a build choice for the environment; confirm compatibility for aggressive surroundings since no chemical data is printed. The automatic drain suits unattended or wet lines, removing condensate without manual intervention.

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 GAFR300 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 GAFR300-10 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 GAF300N10A Is Used
CNC spindle air
Feed a 3/8in line to a CNC spindle air curtain or tool changer. The 40 um element and automatic drain keep condensate from reaching precision components, while the 60 cc bowl handles a shift's worth of water on humid days.
Pneumatic panel feed
Protect a bank of valves and cylinders on a machine panel. The GAF300's 3/8in port matches common manifold inlets, and the automatic drain means no one has to empty the bowl during long automated runs.
Assembly station prep
Clean the air for a hand-held screwdriver or torque tool at an assembly station. The nylon bowl is lighter than metal for overhead mounting, and the included bracket lets you fix it to a beam or frame without extra hardware.
Is the Airtac GAF Filter GAF300N10A the Right Filter?
Choose the body and port first: GAF300 offers 1/4", 3/8", and 1/2" ports, with this 3/8" version sitting between the smaller GAF200 and the larger GAF400. The nylon bowl (N) is a material choice, while the automatic drain (A) handles wet lines; a blank drain would give semi-auto plus manual. The included bracket mounts the unit securely, and the 40 um element is the general-purpose grade, with a 5 um W option for finer filtration. Thread standard is PT; G and NPT are also available to match your fittings. If you need a set pressure, use the matching GAFR300-10 filter-regulator instead, as this GAF does not regulate. The GAF300's 60 cc bowl holds 2.4 times the condensate of the GAF200's 25 cc bowl, meaning fewer drain checks on a mid-size line.
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 GAFR300
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 60 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 360 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 GAFR300-10 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF300N10A FAQ
The GAF300N10A is a filter-only unit with a 3/8" port, 40 um filtering grade, and a 60 cc drain bowl. It weighs 360 g. 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 element is HDPE, and the flow curve is plotted to 6000 L/min.
The A code means this GAF300 has an automatic drain that expels condensate without manual action. It is ideal for wet or unattended lines where the bowl would otherwise fill up. A blank drain code would instead ship with both semi-auto and manual drains for operator control.
