Airtac GAF Filter GAF600C20AJ
The AirTAC Airtac GAF Filter GAF600C20AJ 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 GAF600C20AJ
The GAF600C20AJ is a heavy-duty air filter built to protect large-scale pneumatic systems. Its internal diversion structure spins incoming air, throwing liquid water and solid particles into the 205 cc metal drain bowl while the 40 um HDPE core traps fine grain. This unit only cleans the air; it does not regulate pressure or add lubrication.
This model uses a 3/4in PT-thread port and weighs 1040 g, placing it in the largest GAF size class. The metal bowl and automatic drain make it suitable for permanent installations where regular manual draining is impractical. With a flow curve plotted to 12000 L/min, it suits high-consumption machine headers and multi-station production lines.

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 GAF600C20AJ Is Used
Machine Tool Header
Feed a 3/4in header supplying multiple CNC machines or presses. The 12000 L/min flow envelope and 205 cc bowl handle high intermittent demand while capturing water from compressor condensation.
Multi-Station Assembly Line
Protect dozens of cylinders and valves on a long conveyor system. The automatic drain removes collected water without operator intervention, keeping the line running through shifts.
Paint Spray Booth Supply
Clean the air feeding pneumatic atomizers in a finishing booth. The 40 um element removes pipe scale and water droplets that could ruin a painted surface.
Is the Airtac GAF Filter GAF600C20AJ the Right Filter?
Choose the GAF600 body when your line needs a 3/4in or 1in port and maximum condensate capacity. The 205 cc metal bowl holds over 3x the condensate of the GAF500's 108 cc bowl, so you will drain it far less often. The automatic drain (A) opens by itself when condensate reaches a set level, ideal for wet or unattended lines. The J code means no mounting bracket is included, so plan for panel mounting or an existing support frame. The 40 um element is the general-purpose grade; select the W option for 5 um filtration if you have precision valves downstream. The PT thread standard must match your existing fittings. If you also need to set pressure, use the matching GAFR600-20 filter-regulator instead. The proof pressure of 1.5 MPa against the 0.9 MPa working maximum gives a 1.67x safety margin for burst testing, not for continuous operation.
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 GAF600C20AJ FAQ
This filter uses a 40 um HDPE element and handles 0.15-0.9 MPa (20-130 psi) working pressure, with a 1.5 MPa (215 psi) proof pressure. It operates from -5 to 70 C and must not freeze. The metal drain bowl holds 205 cc and the unit weighs 1040 g. The flow curve is plotted to 12000 L/min.
The A code means an automatic drain. When condensate in the 205 cc metal bowl reaches a preset level, the drain opens and expels the water without manual action. This is ideal for wet compressed-air lines or installations where operators cannot drain the bowl regularly. The J code confirms no bracket is included.
