Airtac GAF Filter GAF500N20AW
The AirTAC Airtac GAF Filter GAF500N20AW 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 GAF500N20AW
The GAF500N20AW 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 core traps fine grain. It protects downstream valves, cylinders and tools from water and dirt, and it does not regulate pressure or carry a gauge.
This 3/4in model weighs 680 g and its flow curve is plotted to 9000 L/min, placing it in the large size class. The automatic drain clears condensate without manual attention, and the included mounting bracket supports the unit's mass on a panel or frame rather than on 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 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 GAF500N20AW Is Used
Machine Header Feed
Feed a 3/4in header supplying multiple pneumatic stations on a production machine, where the 5 um element and automatic drain keep the whole line clean without manual checks.
Multi-Station Assembly Line
Protect a bank of valves and actuators on an assembly line with a single filter point, using the 108 cc bowl to handle condensate between scheduled maintenance windows.
Instrument Air Pre-Filter
Use the 5 um element ahead of precision pneumatic controls or gauging equipment, where fine particle removal is critical and the automatic drain prevents water carryover.
Is the Airtac GAF Filter GAF500N20AW the Right Filter?
Choose the GAF500 body when your line needs a 3/4in port and a 108 cc drain bowl; the smaller GAF400 offers 1/2in ports with a 100 cc bowl and an 8000 L/min curve. The nylon bowl is a build choice, and the 5 um element traps finer particles than the standard 40 um for precision valves or instrument air. The automatic drain suits unattended or wet lines, the included bracket simplifies mounting, and the PT thread standard must match your fittings. For a 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 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 GAF500N20AW FAQ
This air 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. Its drain bowl capacity is 108 cc and it weighs 680 g.
The A code specifies an automatic drain that expels accumulated condensate without manual intervention. This is ideal for unattended operation or wet compressed-air lines where frequent manual draining would be impractical.
