Airtac GAF Filter GAF300C15AW
The AirTAC Airtac GAF Filter GAF300C15AW 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 1/2" ports and a 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF300C15AW
The GAF300C15AW is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 60 cc metal bowl, while the 5 um HDPE element traps fine grain. It is not a regulator and carries no pressure gauge, so it cleans the air without attempting to control pressure.
This 1/2in-port model weighs 360 g and suits a GAF300-size line. The metal bowl and automatic drain make it a fit-and-forget choice for wet lines, and the included bracket supports the 360 g body without relying on 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 GAFR300-15 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 GAF300C15AW Is Used
CNC coolant lines
Feed a 1/2in line to a CNC machine's solenoid bank, where the 5 um element protects precision valves from fine abrasive dust.
Paint booth air prep
Install before a paint spray gun to strip water droplets and scale from the air supply, keeping the finish clean.
Automation test rigs
Protect a laboratory pneumatic test bench with a 1/2in filter that handles up to 6000 L/min of flow on the sizing curve.
Is the Airtac GAF Filter GAF300C15AW the Right Filter?
Choose this GAF300C15AW when you need a 1/2in filter with a metal bowl, an automatic drain, and a 5 um element for finer filtration. The included bracket simplifies mounting, and the PT thread standard matches common local fittings. If you also need to set a pressure, step up to the matching GAFR300-15 filter-regulator instead of expecting this filter to regulate. With a 60 cc bowl, this unit holds about 2.4x the condensate of a GAF200's 25 cc bowl, so you drain it far less often.
Quick checklist
- ✓ Body size for your peak flow (1/2" 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 GAFR300-15 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF300C15AW FAQ
This filter-only unit has a 5 um HDPE element, a 0.15-0.9 MPa (20-130 psi) working range, a 1.5 MPa (215 psi) proof pressure, and a -5 to 70 C temperature range. Its 60 cc drain bowl and 360 g weight define the GAF300 size class.
The C code specifies a metal bowl, which is a build choice for demanding environments, and the A code adds an automatic drain that expels condensate without manual intervention. This combination suits unattended or wet lines, but confirm material compatibility for aggressive surroundings.
