Airtac GAF Filter GAF300C08W
The AirTAC Airtac GAF Filter GAF300C08W 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 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 GAF300C08W
The GAF300C08W is a genuine AirTAC air filter that spins incoming air to throw liquid water and solid particles into its metal drain bowl, while the 5 um HDPE element traps fine grain. This model has a 1/4in port and a 60 cc condensate bowl, and it weighs 360 g.
It is a filter only, so it cleans the air but does not regulate pressure and has no gauge. The metal bowl suits demanding shop environments, and the included mounting bracket lets you fix the 360 g unit to a panel instead of supporting it from the tubing.

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 GAF300C08W Is Used
Protect a precision valve
Feed a single 1/4in solenoid valve on a small assembly fixture. The 5 um element keeps fine particles out of the valve's pilot passages, and the 60 cc bowl gives you time between drain checks.
Instrument air for a gauge
Clean the supply to a sensitive pressure sensor or flow meter on a test bench. The filter removes water and solids before they reach the instrument, and the metal bowl handles the workshop environment.
Guard a small pneumatic cylinder
Protect a 1/4in air cylinder on a packaging or labeling station. The 5 um element traps fine abrasive grain that would wear the cylinder seals, and the included bracket mounts the 360 g filter securely to the machine frame.
Is the Airtac GAF Filter GAF300C08W the Right Filter?
Choose the GAF300C08W when you need a 1/4in port with a 5 um element for finer filtration. The metal bowl is a build choice, and the semi-auto plus manual drain means you can empty it automatically or by hand. The bracket is included, and the PT thread standard must match your fittings. If you also need to set a pressure, use the matching GAFR300-08 filter-regulator instead. The 60 cc bowl holds about 2.4x the condensate of a GAF200's 25 cc bowl, so you drain it less often.
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 GAF300C08W FAQ
The GAF300C08W filters air to 5 um with an HDPE element. 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 a 60 cc drain bowl and weighs 360 g.
The C code means the drain bowl is metal instead of polycarbonate or nylon. It is a build and environment choice, so confirm compatibility for aggressive surroundings. The filter still has the same 5 um grade and 60 cc capacity as other GAF300 bowls.
