The AirTAC Airtac GAF Filter GAF500C20AW 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 3/4" ports and a 108 cc drain bowl. It is a filter only — it does not regulate or set pressure.
The GAF500C20AW is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 108 cc metal bowl, while the 5 um HDPE core traps fine grain. It protects downstream valves and tools from contamination, but it does not regulate pressure and carries no gauge.
This 3/4in model weighs 680 g and is built for higher-flow lines. Its automatic drain clears condensate without manual attention, and the metal bowl suits demanding shop environments. The working range is 0.15-0.9 MPa (20-130 psi) with a proof pressure of 1.5 MPa (215 psi).

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 GAFR500 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 GAFR500-20 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 3/4in header supplying multiple machining centers. The 5 um element protects precision spindles and tool changers from fine abrasive dust.
Protect a bank of cylinders and valves on a final assembly station. The automatic drain keeps the bowl from filling during continuous three-shift operation.
Place this filter ahead of sensitive instrumentation or flow controls. The 5 um grade captures particles that could clog orifices and affect readings.
Choose the GAF500 body when your line needs 3/4in ports and a 108 cc drain bowl; it sits above the GAF400 (100 cc bowl, 8000 L/min curve) and below the GAF600 (205 cc bowl, 12000 L/min curve). The metal bowl is a build choice, not a performance upgrade, so confirm compatibility with your environment. This model has the automatic drain (A), the included mounting bracket, a 5 um element (W), and PT port threads. If you also need to set pressure, use the matching GAFR500-20 filter-regulator instead. The GAF500's 108 cc bowl holds about 1.08x the condensate of the GAF400's 100 cc bowl, so service intervals are nearly identical between these two bodies.
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 GAFR500-20 filter-regulator as your air-prep needs grow.
This is a filter-only unit with a 5 um HDPE element, a 3/4in PT port, and a 108 cc metal drain bowl. It weighs 680 g and has a flow curve plotted to 9000 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. It uses an automatic drain.
The automatic drain (A) expels accumulated condensate without manual intervention. This is ideal for wet lines or unattended operation. The metal bowl is durable for industrial environments, but confirm material compatibility with any aggressive chemicals present.
