The AirTAC GFR600C20AF2T AirTAC Filter Regulator 3/4 in NPT is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR600C20AF2T is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has a 3/4 in NPT port, a 40 um filter element, an automatic drain, and an embedded square gauge reading in psi. The aluminium alloy bowl suits this larger frame, the standard regulator covers 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. GFR filter regulators are available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of drain type, 40 um or 5 um (code W) filtration, gauge scale options, PT, G or NPT thread, and an optional reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Point-of-use filter regulation for a CNC machining cell: clean, moisture-reduced air at a set pressure to the machine's pneumatic valves and clamps, with the automatic drain handling condensate without operator attention.
Filtered, regulated air for the cylinders and grippers on a packaging or palletising line, holding set pressure stable through the shift while the 40 um element protects valve and cylinder seals.
A 3/4 in filter regulator on the air header feeding a bottling or filling line, supplying downstream air cylinders and gating at a controlled pressure while condensate is drained automatically.
Size and port set the flow path: within the GFR range, sizes 200/300/400/600 step up in port and flow capacity, and this unit sits at the top of the range with a 3/4 in NPT port - match the size to your air demand. Drain choice matters: automatic (as fitted here), manual, or differential-pressure; automatic drainage suits installations that are unmanned or hard to reach. Filtration is 40 um standard; specify code W for 5 um where finer particulate removal is needed. The embedded square gauge reads psi on this unit, with MPa and bar scales as alternatives and an external round gauge optional. Thread: PT is the AirTAC standard, with G (BSPP) and NPT as catalogue options; a mounting bracket is included. Flow is published as curves, not a single rating - ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 as curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and datasheet figures for you on request.
The trailing T means this unit has a 3/4 in NPT thread. PT is the AirTAC standard thread and G (BSPP) is also a catalogue option - the thread is specified when ordering, so choose the one that matches your piping.
