The AirTAC GFR600C20F1WTK AirTAC Filter Regulator NPT3/4 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 AirTAC GFR600C20F1WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 3/4 in NPT port, 5 um filtration (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square pressure gauge scaled in MPa, and a reverse/check valve fitted to hold downstream pressure. The metal bowl on this size 600 unit is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with a standard regulation range of 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, G/NPT thread options, and an optional bracket. Flow is published in the catalogue as curves rather than a single rated figure, so ask us to confirm sizing or any datasheet figure for your application before ordering.

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.

Installed at the take-off of a factory compressed-air ring main, the unit strips water and particles to 5 um and sets a stable regulated pressure for the downstream distribution leg serving multiple workstations.
Feeding the air cylinders and actuators on a packaging or conveyor line, the regulator holds a constant working pressure so clamp and push strokes stay repeatable, while the 5 um grade protects valve spools from particulate.
Mounted ahead of solenoid valve manifolds and pneumatic actuators on process equipment, the unit delivers clean, regulated air, and the fitted check valve holds the downstream circuit pressurised if the upstream supply drops.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range, suited to lines with higher air consumption. Filtration here is the 5 um grade (code W) instead of the 40 um standard, so pick it where downstream valves, cylinders or instruments need finer particle removal; the differential-pressure drain handles condensate automatically, while automatic or manual drains are the other catalogue choices. The square MPa gauge is fitted, with psi or bar scales and an external round gauge available as options, and the reverse/check valve (code K) is fitted to prevent downstream pressure decay. Thread is NPT here; PT is the standard and G is also a catalogue option. A bracket is included for mounting.
Because flow is published as curves and not a single rated number, we cannot quote one figure here: send us your air demand and line conditions and we will confirm sizing against the datasheet before you order.
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 GFR series as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Send us your air demand and application details and we will confirm the sizing and the relevant datasheet figures on request.
The W in the code selects the 5 um filter element instead of the 40 um standard, giving finer particle removal for sensitive downstream components. The K code means a reverse/check valve is fitted, which prevents downstream pressure from bleeding back through the unit. Both are standard catalogue options on the GFR filter regulator.
