Airtac GAF Filter GAF300C15AJW
The AirTAC Airtac GAF Filter GAF300C15AJW 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 GAF300C15AJW
The GAF300C15AJW 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 core traps fine grain. It has no regulator, no gauge, and no lubricator - it cleans the air but does not control pressure. This 1/2in model weighs 360 g and carries a flow curve plotted to 6000 L/min.
With its metal bowl and automatic drain, this unit suits lines where condensate must be expelled without manual attention. The 5 um element captures far finer particles than the standard 40 um grade, making it a strong fit for precision valves or instrument air. Its 360 g mass means it needs a proper panel or frame mount, not support 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 GAFR300-15 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 GAF300C15AJW Is Used
Precision valve protection
Feed a bank of precision pneumatic valves on a machining center with 5 um filtered air, keeping fine abrasive dust out of spool clearances.
Instrument air pre-filter
Protect sensitive instrumentation or flow meters on a test bench where fine particle carryover could skew readings or clog orifices.
Wet compressor line
Mount on a humid compressor discharge line where the automatic drain reliably ejects condensate without daily manual attention.
Is the Airtac GAF Filter GAF300C15AJW the Right Filter?
Choose the GAF300 body when your line needs 1/2in ports and a 60 cc condensate bowl; step up to the GAF400 for 100 cc capacity and an 8000 L/min envelope, or down to the GAF200 for a lighter 25 cc bowl. The metal bowl here is a build choice for tougher surroundings - confirm compatibility for aggressive environments. The A code gives you an automatic drain for unattended or wet lines, while the J code omits the bracket for panel-mount installations. The W element is 5 um for finer filtration, and the PT thread standard must match your fittings. If you also need a set pressure, use the matching GAFR300-15 filter-regulator instead. The GAF300's 60 cc bowl holds 2.4x the condensate of the GAF200's 25 cc bowl, meaning fewer drain interventions.
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 GAF300C15AJW FAQ
This AirTAC filter has a 5 um filtering grade, a working pressure range of 0.15-0.9 MPa (20-130 psi), a proof pressure of 1.5 MPa (215 psi), and a temperature range of -5 to 70 C. It has a 60 cc drain bowl and weighs 360 g.
The A code specifies an automatic drain, which expels condensate automatically without manual intervention. This is ideal for unattended operation or wet lines. The J code means no mounting bracket is included, and the W code indicates the 5 um filter element.
