The AirTAC Airtac GAF Filter GAF300N08JW 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.
The GAF300N08JW is a genuine AirTAC air filter that spins incoming air to throw liquid water and solid particles into its 60 cc nylon bowl, then traps fine grain with a 5 um HDPE element. It is a filter only - there is no regulator, no pressure gauge and no lubricator, so it cleans the air but never sets or controls pressure.
This 1/4in-port model weighs 360 g and is rated for 0.15-0.9 MPa (20-130 psi) working pressure with a 1.5 MPa (215 psi) proof pressure, operating from -5 to 70 C. The nylon bowl and included semi-auto plus manual drains make it a straightforward choice for a compact machine station that needs clean air delivered to a single valve or small jig.

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.

Feed a single precision pneumatic valve on a small assembly fixture with 5 um filtered air, keeping fine abrasive grain away from the valve's internal seals and spool.
Mount this 360 g filter on a small indexing table or benchtop machine where space is tight and the 1/4in port matches the existing tubing run.
Protect a hand-held pneumatic tool on a short production run, using the manual drain to check and empty the 60 cc bowl between shifts.
Choose the GAF300N08JW when your line needs 1/4in ports and a 5 um element for finer filtration, with the nylon bowl for build flexibility and the semi-auto plus manual drains for controlled condensate removal. The J code means no mounting bracket is included, so plan for a panel mount or an existing bracket, and the PT thread standard must match your fittings. If you also need a set pressure, step up to the matching GAFR300-08 filter-regulator instead, since this GAF does not regulate. With a 60 cc drain bowl versus 25 cc on the GAF200, this unit holds about 2.4x the condensate before you need to drain it.
Quick checklist
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.
The GAF300N08JW is a 1/4in port air filter with a 5 um HDPE element, a 60 cc nylon bowl, and a semi-auto plus manual drain. It weighs 360 g and has a flow curve plotted to 6000 L/min. The working pressure range is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C.
The J in GAF300N08JW means the mounting bracket is omitted. This suits installations where the filter is panel-mounted or secured with an existing bracket. The unit itself is a filter only, so it does not include a regulator, gauge, or any pressure-control components.
