Airtac GAF Filter GAF30008W
The AirTAC Airtac GAF Filter GAF30008W 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 GAF30008W
The GAF30008W is a genuine AirTAC air filter that uses a diversion structure to spin incoming air, throwing liquid water and solid particles into its 60 cc drain bowl before the 5 um HDPE element traps fine grain. It is a filter only, with no regulator or pressure gauge, and it cleans the air without controlling pressure.
This model has a 1/4in port and a PC bowl, weighs 360 g, and is rated for 0.15-0.9 MPa (20-130 psi) working pressure. The 5 um element suits precision valves or instrument air, and the included mounting bracket supports the unit's size class properly.

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 GAF30008W Is Used
Precision valve protection
Feed a bank of precision pneumatic valves on a small assembly machine. The 5 um element stops fine abrasive grain that could wear spools and orifices, while the 60 cc bowl collects condensate before it reaches the valve pilots.
Instrument air for gauges
Protect sensitive air gauges and sensors on a test bench. The 5 um filtration grade removes particles that could clog tiny sensing ports, and the semi-auto drain keeps the bowl from filling during light-duty cycles.
Small jig and fixture lines
Mount this filter upstream of a single pneumatic jig or clamping fixture. The 1/4in port matches common tubing, and the 360 g body is light enough for a frame bracket while still providing 60 cc of condensate capacity.
Is the Airtac GAF Filter GAF30008W the Right Filter?
Choose the GAF30008W when your line needs 1/4in porting and fine 5 um filtration. The PC bowl is a build choice, and the semi-auto plus manual drain lets you empty condensate on a schedule or automatically when the float trips. The included bracket simplifies panel mounting, and the PT thread standard matches common local fittings. If you also need a set pressure, use the matching GAFR300-08 filter-regulator instead, since a plain GAF does not regulate. The 6000 L/min flow envelope is 2x the GAF200's 3000 L/min curve, so this body steps up capacity for a small machine station.
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 GAF30008W FAQ
The GAF30008W is a filter only with a 5 um HDPE element and a 60 cc drain bowl. 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 weighs 360 g and has a flow curve plotted to 6000 L/min. The body has a 1/4in port with PT thread.
The W code specifies a 5 um element instead of the standard 40 um. This traps far finer particles, which is valuable for precision valves or instrument air, but the finer element will load with dirt faster and need more frequent service. The element is a replaceable HDPE core.
