Airtac GAF Filter GAF50020A
The AirTAC Airtac GAF Filter GAF50020A 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 GAF50020A
The GAF50020A is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 108 cc drain bowl, while the HDPE core traps fine grain. It protects downstream valves and cylinders from contamination, but it does not regulate pressure and has no gauge.
This model uses a 3/4in port, a 40 um element, and an automatic drain. The 680 g body places it in the GAF500 size class, which suits larger machine headers or multi-station lines where a smaller filter would need constant attention.

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 GAF50020A Is Used
Machine Header Protection
Feed a 3/4in header serving multiple pneumatic stations on a production line, keeping water and scale out of downstream valves.
Multi-Station Assembly
Protect a bank of cylinders and actuators on an automated assembly cell where a larger bowl reduces maintenance stops.
High-Cycle Tooling
Supply clean air to high-cycle tooling that would otherwise suffer from water carryover and particle wear.
Is the Airtac GAF Filter GAF50020A the Right Filter?
Choose the GAF50020A when you need a 3/4in port with a 40 um element and an automatic drain for wet or unattended lines. The included mounting bracket supports the 680 g body, while the PC bowl suits general-purpose use. If you need finer filtration, select the W option for a 5 um element; if you need pressure control, use the matching GAFR500-20 filter-regulator instead. The automatic drain here eliminates manual draining, and the 108 cc bowl holds about 4.3x the condensate of a GAF300's 60 cc bowl, so you will intervene far less often.
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 GAF50020A FAQ
It is a 40 um air filter with a 3/4in PT port, a 108 cc drain bowl, and a weight of 680 g. 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 HDPE element is rated for air only.
The A code means the GAF50020A has an automatic drain that expels condensate without manual intervention, ideal for wet lines or unattended operation. A non-A model would include both semi-auto and manual drains, requiring periodic manual opening.
