Airtac GAF Filter GAF300C10
The AirTAC Airtac GAF Filter GAF300C10 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 GAF300C10
The AirTAC GAF300C10 is a filter-only unit that spins incoming air to fling liquid water and solid particles into its 60 cc metal drain bowl, while the 40 um HDPE element traps fine grain. It protects downstream valves and cylinders from contamination; it does not regulate pressure and has no gauge.
This 3/8in port model weighs 360 g and uses a metal bowl for demanding environments. Its flow curve is plotted to 6000 L/min, giving a clear sizing envelope for medium-duty machine circuits.

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 GAF300C10 Is Used
CNC machine air prep
Feed clean, dry air to a CNC spindle or tool changer with a 3/8in line. The 40 um element stops rust and scale from reaching precision components.
Pneumatic panel assembly
Mount this 360 g filter on a control panel for a stamping press or assembly station. Its metal bowl resists knocks in a busy workshop.
Packaging line air supply
Protect cylinders and sensors on a carton erector or strapping machine. The 60 cc bowl gives a practical buffer between maintenance rounds.
Is the Airtac GAF Filter GAF300C10 the Right Filter?
Choose the GAF300C10 for a 3/8in air line needing filtration at 40 um with a metal bowl that stands up to rough shop conditions. The semi-auto drain plus manual backup means you can purge condensate on a schedule or manually when needed. The included mounting bracket simplifies panel installation, and the PT thread standard matches common local fittings. If you need finer filtration, select the W option for a 5 um element; if you need pressure control, step up to the GAFR300-10 filter-regulator instead. With a 60 cc bowl versus GAF200's 25 cc, this unit holds about 2.4x more condensate before draining.
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 GAF300C10 FAQ
Filtering grade is 40 um. Working pressure range is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi). Temperature range is -5 to 70 C. Drain bowl capacity is 60 cc and weight is 360 g. Flow curve is plotted to 6000 L/min.
The C code specifies a metal bowl instead of the standard polycarbonate. It is a build choice for tougher environments; confirm compatibility with any aggressive chemicals or solvents you use, as AirTAC publishes no chemical-resistance data for it.
