Airtac GAF Filter GAF500N20W
The AirTAC Airtac GAF Filter GAF500N20W 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.

About the Airtac GAF Filter GAF500N20W
The GAF500N20W is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 108 cc nylon bowl, while the 5 um HDPE element traps fine grain. It is not a regulator and carries no pressure gauge, so it cleans the air without attempting to control pressure.
This 3/4in model weighs 680 g and its flow curve is plotted to 9000 L/min, placing it in the upper-middle size class of the GAF family. The nylon bowl is a build choice for the environment, and the semi-auto plus manual drain gives you both automatic condensate release and a manual backup for service checks.

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.

Where the Airtac GAF Filter GAF500N20W Is Used
Machine tool air preparation
Feed a 3/4in line serving a CNC machine's pneumatic clamps and tool changers, where the 5 um element protects precision valves from fine abrasive dust.
Assembly line header supply
Protect a multi-station assembly line where several workstations draw from one 3/4in header, with the 108 cc bowl reducing drain checks between shifts.
Paint booth air cleaning
Clean compressed air before it reaches paint spray equipment, where water droplets and particles would otherwise ruin the finish.
Is the Airtac GAF Filter GAF500N20W the Right Filter?
Choose the GAF500 when a 3/4in port and a 108 cc drain bowl match your line's condensate load; step up to the GAF600 for a 205 cc bowl and a 12000 L/min envelope, or down to the GAF400 for a 100 cc bowl and 8000 L/min. The nylon bowl suits applications where you prefer its material properties, while the 5 um element traps finer particles than the standard 40 um for precision valves or instrument air. The included bracket supports the 680 g body properly, and the PT thread standard must match your existing fittings. If you also need a set pressure, the matching GAFR500-20 adds a regulator, but this filter alone does not regulate. The GAF500's 108 cc drain bowl holds about 1.08x the condensate of the GAF400's 100 cc bowl, so service intervals are nearly identical between these two neighbours.
Quick checklist
- ✓ Body size for your peak flow (3/4" 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 GAFR500
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 108 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 680 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 GAFR500-20 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF500N20W FAQ
The GAF500N20W is a filter-only unit with a 5 um HDPE element, a 3/4in PT port, and a 108 cc nylon 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 has both semi-auto and manual drains and includes a mounting bracket.
The N in the model code indicates a nylon bowl, as opposed to a PC bowl (blank) or metal bowl (C). Nylon is a build material choice for the drain bowl, and the common specification is identical across all three materials. Confirm compatibility with your specific environment, as no temperature, chemical, or impact data is printed for the bowl materials.
