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 unit: a diversion structure spins the incoming air so liquid water and solid particles are flung out into the drain bowl, where a 40 um HDPE element catches the remaining fine grain. It carries no regulator, no pressure gauge and no adjusting knob, so it never sets, limits or holds a downstream pressure. This model has a 3/4" NPT port, a 205 cc metal drain bowl and both a semi-auto drain and a manual drain fitted.
At 1040 g this is the heaviest body in the GAF range, so fix it to a panel or frame instead of letting the tubing carry its mass. The rated working 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, with a flow curve plotted to 12000 L/min for sizing. It is built to clean the supply feeding valves, cylinders and tools across a whole machine header; if the line also needs a set pressure, add the matching GAFR600-20 or a separate GAR regulator.

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.

Installed at the drop feeding a large machine's air header, the 3/4" port and a curve plotted to 12000 L/min let one unit clean the supply for every valve and cylinder on that header.
A long conveyor run with many actuation stations draws enough air to justify this body, and the 205 cc condensate bowl means fewer trips down the line to bleed each filter.
Placed first in the train at a machining cell's wall drop, it removes bulk water and chips of dirt before the air reaches the machine's own valves and actuators.
This 3/4" port model sits at the top of the GAF range; if your circuit draws less air, step down to a GAF500, whose curve is plotted to 9000 L/min. The metal bowl is the only bowl option on the GAF600, and the C20T ships with both a semi-auto drain and a manual drain, so someone still has to bleed condensate unless you order the A version with an automatic drain instead. The mounting bracket is included, the 40 um element suits general machine air (order the W code for a 5 um element on precision valves or instrument take-offs), and the T code sets NPT port threads, so match your fittings to NPT. A plain GAF does not regulate, so the path for pressure control is the GAFR600-20 or a standalone GAR. The 205 cc drain bowl holds roughly 1.9x the condensate of the 108 cc bowl on a GAF500, which stretches the time between manual bleed-offs.
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.
It is a filter-only unit with a 40 um HDPE element on a 3/4" NPT port. 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 metal drain bowl holds 205 cc, the unit weighs 1040 g, and its flow curve is plotted to 12000 L/min.
The GAF600 body is supplied with a metal bowl only; the PC and nylon bowls belong to the smaller GAF200 to GAF500 bodies. The pressure range, temperature range and filtering grades are identical for every bowl material, so treat the metal bowl as a build choice and confirm its compatibility with any aggressive surroundings before ordering.
