Airtac GAF Filter GAF600C20J
The AirTAC Airtac GAF Filter GAF600C20J 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 205 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF600C20J
The GAF600C20J is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 205 cc metal bowl, while the 40 um HDPE core traps fine grain. It protects downstream valves and cylinders from contamination, but it does not regulate pressure or remove oil.
This model uses a 3/4in PT port and weighs 1040 g, placing it in the largest GAF size class. The metal bowl is the only option for the GAF600 body, and the unit ships without a mounting bracket, so plan for a panel or frame mount rather than supporting it from 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 GAFR600 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 GAFR600-20 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 GAF600C20J Is Used
Machine Header Feed
Feed a 3/4in header supplying multiple pneumatic stations on a production line, where the 12000 L/min envelope supports high simultaneous demand.
Multi-Station Assembly
Protect a bank of valves and actuators on a multi-station assembly machine, where the 205 cc bowl handles condensate from long continuous runs.
Central Plant Air Drop
Install at the takeoff point for a large conveyor system or plant air drop, filtering solids and water before the air reaches downstream equipment.
Is the Airtac GAF Filter GAF600C20J the Right Filter?
Choose the GAF600 body for high-flow main lines where a 3/4in port and 205 cc condensate bowl minimize maintenance frequency. The metal bowl suits demanding environments, but confirm compatibility for aggressive surroundings since no chemical data is printed. This model includes both semi-auto and manual drains, so you can drain manually or let the semi-auto mechanism release condensate when pressure drops. The J code means no bracket is included, so use an existing bracket or panel mount. The 40 um element handles general workshop air; select the W version for 5 um filtration if you have precision valves downstream. The PT thread standard must match your fittings. If you also need pressure control, use the matching GAFR600-20 filter-regulator instead. The GAF600's 205 cc bowl holds about 8.2x the condensate of the GAF200's 25 cc bowl, so this unit needs far fewer drain interventions.
Quick checklist
- ✓ Body size for your peak flow (3/4" here)
- ✓ Element 40 µm (general) or 5 µm (fine)
- ✓ Bowl material: Metal (C) only
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Bracket kept or removed (J)
- ✓ Need pressure control too? Use GAFR600
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 205 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1040 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 GAFR600-20 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF600C20J FAQ
The GAF600C20J is a filter-only unit with a 40 um HDPE element, 3/4in PT port, and 205 cc metal bowl. Working 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. It weighs 1040 g and has a flow curve plotted to 12000 L/min.
The J in GAF600C20J means the mounting bracket is omitted. This is for installations using an existing bracket or a panel mount. The unit still has both semi-auto and manual drains fitted, and the metal bowl is standard for the GAF600 body. You must provide your own mounting solution.
