Airtac GAF Filter GAF500C20
The AirTAC Airtac GAF Filter GAF500C20 is a genuine compressed-air filter. Its diversion structure spins the air to separate liquid water and trap solid particles down to 40 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 GAF500C20
The GAF500C20 is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 108 cc metal bowl, while the 40 um HDPE element traps fine grain. It protects downstream valves and tools from contamination without regulating pressure or adding a gauge.
This 3/4in model weighs 680 g and uses a metal bowl with both semi-auto and manual drains fitted. Rated for 0.15-0.9 MPa (20-130 psi) and -5 to 70 C, it handles high-flow lines where a smaller filter would need constant draining.

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 GAF500C20 Is Used
Machine Header Feed
Protect a 3/4in main line feeding multiple pneumatic cylinders on a stamping press, where the 108 cc bowl handles condensate between shifts.
Plant Air Drop
Install at a 3/4in drop leg serving a bank of air tools, using the semi-auto drain to purge water each time the downstream pressure cycles.
Conveyor System
Guard a long conveyor's valve manifold with a 680 g filter that mounts rigidly to the frame, keeping water out of solenoid pilot lines.
Is the Airtac GAF Filter GAF500C20 the Right Filter?
Choose the GAF500 for 3/4in lines needing a 108 cc condensate bowl and 9000 L/min flow envelope, stepping up from the GAF400's 100 cc bowl and 8000 L/min curve. The metal bowl suits demanding environments, while the included bracket simplifies mounting; the semi-auto drain releases water when pressure drops, with a manual backup for service. The 40 um element covers general shop air, and PT threads match standard local fittings. If you also need pressure control, pair this with a GAR regulator or upgrade to the GAFR500-20 filter-regulator. The proof pressure of 1.5 MPa gives about a 1.67x margin over the 0.9 MPa working maximum, a burst-test figure not a running limit.
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 GAF500C20 FAQ
Filtering grade is 40 um. Pressure range 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 drain bowl holds 108 cc and the unit weighs 680 g, with a flow curve plotted to 9000 L/min.
It has both a semi-auto drain and a manual drain fitted. The semi-auto type opens automatically when air pressure drops to zero, releasing collected condensate, while the manual drain lets you purge the bowl on demand during operation.
