The AirTAC Airtac GAF Air Filters GAF600C20T 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.
The AirTAC GAF600C20T is a filter only. A diversion structure spins the incoming air so liquid water and solid particles are flung into the 205 cc drain bowl, while the 40 um HDPE element holds back the fine grain that would otherwise reach your valves, cylinders and tools. It neither sets nor reads pressure, so no instrument or adjustment hardware is fitted. This model carries a 3/4in NPT port, a metal bowl, and both a semi-automatic and a manual drain, with the mounting bracket included in the box. At 1040 g it is the heaviest GAF body, so fix it to a panel or frame instead of letting the tubing bear the load. For sizing, the plotted flow curve runs to 12000 L/min, the widest envelope in the GAF range.

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.

Drops into a 3/4in header feeding a production machine, spinning condensate and swarf-laden grit out before air reaches the distribution manifold.
Its 12000 L/min curve envelope and 205 cc bowl suit a line where many cylinders and actuators draw from one filtered supply point.
High condensate loads from long compressed-air runs collect in the large metal bowl, keeping the machine's directional valves clean.
Pick the 600 body when your main line is 3/4in and you want the biggest safety margin: the GAF500 below it takes the same 3/4in port but its curve stops at 9000 L/min and its bowl holds 108 cc rather than 205 cc. The 600 body is supplied with a metal bowl only, as PC and nylon are not offered at this size. This code keeps the semi-auto plus manual drain pair, includes the bracket, and uses the general-purpose 40 um element; switch to the W code for 5 um filtration when precision valves sit downstream, or to the A code for an automatic drain on unattended runs. NPT is the port thread here, so match your NPT fittings accordingly. Should the line also need a set pressure, the matching GAFR600-20 puts a regulator behind the same filtration, since this unit alone never regulates. The 205 cc drain bowl holds about 8x the condensate of the 25 cc bowl on a GAF200, so crews drain it far less often.
Quick checklist
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.
Filtering grade is 40 um with an HDPE element, and the working pressure range is 0.15-0.9 MPa (20-130 psi) with a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 205 cc, the unit weighs 1040 g, the port is 3/4in NPT, and the flow curve is plotted to 12000 L/min. The bowl is metal and both semi-auto and manual drains are fitted.
The GAFR600-20 combines this same filtration with a built-in pressure regulator, so it both cleans the air and holds a set downstream pressure. The GAF600C20T cleans only: water and solids spin into the 205 cc bowl and the 40 um element traps fine grain, but the unit has no way to adjust or control pressure. Add a separate GAR regulator if you prefer to keep filtration standalone.
