Airtac GAF Filter GAF600C20AJW
The AirTAC Airtac GAF Filter GAF600C20AJW 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 205 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF600C20AJW
The GAF600C20AJW is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 205 cc metal drain bowl, while the 5 um HDPE core traps fine grain. It cleans the air for downstream valves and cylinders, but it does not regulate pressure and carries no gauge.
This 3/4in-port model weighs 1040 g, which places it in the largest GAF size class and tells you it needs a proper panel or frame mount rather than support from the tubing. The metal bowl and automatic drain suit a fixed installation where the filter stays in place and the line may see wet conditions.

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 GAF600C20AJW Is Used
Machine Header Feed
Feed a 3/4in header that supplies multiple stations on a large machine, where the 12000 L/min envelope and 205 cc bowl reduce how often the line needs attention.
Multi-Station Assembly Line
Protect a bank of valves and cylinders on a multi-station assembly line, where the 5 um element keeps fine grain away from precision pilot valves.
Instrument Air Pre-Filter
Use it ahead of sensitive instrumentation that needs 5 um filtration, with the automatic drain handling condensate in a wet compressed-air supply.
Is the Airtac GAF Filter GAF600C20AJW the Right Filter?
Choose the GAF600 body when your line is 3/4in or 1in and you need the 205 cc drain bowl, which holds roughly twice the condensate of the GAF500's 108 cc bowl. The metal bowl is a build choice for this size, and the automatic drain (A) clears water without manual attention, while the J code means no bracket is included, so plan for a panel mount or an existing bracket. The 5 um element (W) traps finer particles than the standard 40 um for precision equipment, and the PT thread standard must match your fittings. If the line also needs a set pressure, use the matching GAFR600-20 filter-regulator instead, since this GAF does not regulate. The proof pressure of 1.5 MPa against the 0.9 MPa working top gives about a 1.67x margin, which is a burst-test figure, not a license to run above the rated range.
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 GAF600C20AJW FAQ
It is a filter-only unit with a 5 um HDPE element, a 3/4in PT port, a 205 cc metal bowl, and a weight of 1040 g. The working pressure range is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C. The flow curve is plotted to 12000 L/min.
The A code specifies an automatic drain, which expels condensate from the 205 cc metal bowl without manual intervention. This suits unattended or wet lines, unlike the semi-auto plus manual drain on blank-code models, and the metal bowl is the only option for the GAF600 body.
