Airtac GAF Filter GAF500C20AJW
The AirTAC Airtac GAF Filter GAF500C20AJW 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 GAF500C20AJW
The GAF500C20AJW is a filter-only unit that spins incoming air to throw liquid water and solid particles into its metal drain bowl, while the 5 um HDPE element traps fine grain. It cleans the air stream; it does not regulate pressure and carries no gauge.
This 3/4in model has a 108 cc metal bowl and weighs 680 g, placing it in the upper size class for high-flow lines. The automatic drain clears condensate without manual attention, and the 5 um element suits precision valves downstream.

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 GAF500C20AJW Is Used
Machine header feed
Feeds a 3/4in header supplying multiple pneumatic stations on a production machine, protecting downstream valves from water and scale.
Multi-station assembly line
Serves a bank of cylinders and actuators on an assembly line, with the automatic drain handling condensate without line shutdown.
Instrument air prefilter
Placed ahead of precision pneumatic controls, the 5 um element traps fine particles that could clog small orifices.
Is the Airtac GAF Filter GAF500C20AJW the Right Filter?
Choose the GAF500 body when a 3/4in port and a 9000 L/min flow envelope are needed; step down to the GAF400 for 1/2in lines with an 8000 L/min envelope. The metal bowl is a build choice for demanding environments, though AirTAC prints no chemical or impact data, so confirm compatibility for aggressive surroundings. The A code gives an automatic drain for wet or unattended lines, while the J code omits the mounting bracket for panel-mount installations. The W element filters to 5 um instead of the standard 40 um, trading finer filtration for more frequent element service. PT port threads are standard; G and NPT are available. If the line also needs a set pressure, use the matching GAFR500-20 filter-regulator instead. The 1.5 MPa proof pressure is about 1.67x the 0.9 MPa top of the working range, a burst-test margin rather than a running allowance.
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 GAF500C20AJW FAQ
This AirTAC GAF500 is a filter only with a 3/4in port, 5 um filtering grade, 108 cc metal drain bowl, and 680 g weight. 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. The flow curve is plotted to 9000 L/min.
The A specifies an automatic drain that expels condensate without manual operation, ideal for wet or unattended lines. The J means the mounting bracket is omitted, so you plan for a panel mount or an existing bracket. This model has no regulator, gauge, or lubricator.
