Airtac GAF Filter GAF300C08
The AirTAC Airtac GAF Filter GAF300C08 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 1/4" ports and a 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF300C08
The GAF300C08 is a genuine AirTAC air filter that removes water and solid particles from compressed air lines using a diversion structure that spins the air, throwing contaminants into the drain bowl. This model has a 1/4in port, a 40 um HDPE filter core, and a 60 cc metal bowl, weighing 360 g.
This filter-only unit does not regulate pressure, so it is ideal for protecting downstream equipment like valves and cylinders. The metal bowl is a build choice for environments where you need extra durability, but confirm compatibility for aggressive surroundings. The semi-auto and manual drains give you flexible condensate removal options.

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 GAFR300-08 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 GAF300C08 Is Used
Protect a Single Jig
Use the GAF300C08 on a 1/4in line feeding a single pneumatic jig or fixture, ensuring clean air reaches the actuating cylinder.
Guard a Bench Valve
Install this filter upstream of a manual control valve on a workbench to keep water and dirt from affecting valve operation.
Feed a Small Tool
Protect a small air tool or a single station on an assembly line with this 1/4in filter, preventing grit from wearing internal parts.
Is the Airtac GAF Filter GAF300C08 the Right Filter?
Choose the GAF300C08 for a 1/4in line needing clean air without pressure control. The metal bowl (C) is a build choice, while the included bracket simplifies mounting. The 40 um element handles general filtration, and the PT thread standard matches common fittings. For a smaller line, the GAF200 offers a 25 cc bowl, while the GAF400 steps up to a 100 cc bowl for higher volume needs. If you also need to set pressure, the matching GAFR300-08 adds a regulator. The 60 cc drain bowl holds about 2.4x the condensate of the GAF200's 25 cc bowl, meaning fewer manual drain checks.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 GAFR300-08 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF300C08 FAQ
The GAF300C08 is an air filter with a 40 um filtering grade, a working pressure range of 0.15-0.9 MPa (20-130 psi), and a proof pressure of 1.5 MPa (215 psi). It operates in temperatures from -5 to 70 C, has a 60 cc drain bowl, and weighs 360 g.
The 'C' in the model code indicates a metal bowl, which is a build and environment choice. The common specifications are the same as for PC or nylon bowls, so you should confirm compatibility for your specific surroundings. This model also includes both semi-auto and manual drains.
