Airtac GAF Filter GAF300N10W
The AirTAC Airtac GAF Filter GAF300N10W 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 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF300N10W
The GAF300N10W is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 60 cc nylon bowl, while the 5 um HDPE element traps fine grain. It cleans the air for downstream components; it does not regulate pressure and has no gauge.
This 3/8in model weighs 360 g and sits in the GAF300 size class, a step above the 200 g GAF200. With a 5 um element it suits precision valves or instrument air, and the nylon bowl is a build choice for environments where you prefer its material profile.

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 GAF300N10W Is Used
Instrument Air Feed
Protect a precision pneumatic valve or a small instrument-air loop on a machining station. The 5 um element traps fine particles that could clog sensitive pilot ports.
Machine Tool Line
Mount on a 3/8in line feeding a drill or a small assembly fixture. The 60 cc bowl handles typical condensate between shifts, and the manual drain gives a quick daily purge.
Dedicated Branch Line
Use on a dedicated branch feeding a single automated workcell. The semi-auto drain releases water when pressure drops, reducing the need for frequent manual checks.
Is the Airtac GAF Filter GAF300N10W the Right Filter?
Choose the body and port to match your line size: GAF300 offers 1/4in, 3/8in and 1/2in ports, while the smaller GAF200 tops out at 1/4in and the larger GAF400 starts at 3/8in with a 100 cc bowl. The nylon bowl here is a material choice with the same common spec as PC or metal, so confirm compatibility for aggressive surroundings. This model ships with both semi-auto and manual drains, the included mounting bracket, and a 5 um element for finer filtration; the PT thread standard must match your fittings. If you also need a set pressure, use the matching GAFR300-10 filter-regulator instead. The 6000 L/min flow envelope is double the GAF200's 3000 L/min curve, so this body can feed a larger branch 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 GAF300N10W FAQ
It is a filter-only unit with a 5 um HDPE element, a 60 cc drain bowl, and a weight of 360 g. The working pressure range is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C. The flow curve is plotted to 6000 L/min.
The N in GAF300N10W indicates a nylon bowl, one of three material options (PC, metal, nylon). The common specification is identical for all three, so the choice is about build and environment. Confirm compatibility for aggressive surroundings, as no temperature or chemical data is printed.
