The AirTAC GFR600C20ALC3WTK 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 GFR600C20ALC3WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built for a 3/4 in NPT port, carries a 5 um filter element (code W) for finer filtration than the standard 40 um grade, and drains condensate automatically, so the bowl does not depend on an operator or a pressure differential to empty. It is the low-pressure regulator type, and the code C3 specifies a round external gauge with a bar scale. A reverse (check) valve is fitted (code K) and a mounting bracket is included.
This is a genuine AirTAC part in the largest GFR frame: the 600 size, with the aluminium alloy bowl that the catalogue specifies for this frame. Across the GFR range, sizes 200 to 600 cover port sizes from 1/8 in to 1 in, with manual or automatic drains, 40 um or 5 um elements, standard or low-pressure regulation, embedded square or external round gauges, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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.

Feeding a carton-sealing or shrink-wrap machine section that runs at low regulated pressure: the GFR600C20ALC3WTK filters water and scale out of the shop-air drop and holds the reduced setting, with the automatic drain clearing condensate from the aluminium bowl unattended.
Mounted at the machine's 3/4 in air inlet on the included bracket, the unit conditions the whole supply in one body - 5 um filtration ahead of sensitive valves and cylinders, regulated pressure to the machine circuit, and the bar-scale round gauge for operator checks.
Installed on a workshop ring-main takeoff serving impact tools, blow guns and small actuators: the filter stage keeps rust and water out of the tools, the low-pressure regulator type sets a safe working pressure, and the check valve stays in the line as specified by the K code.
Size 600 with a 3/4 in NPT port is the right step when your line's flow demand sits at the top of the G-series port range; if your circuit draws less air, a 300 or 400 frame on a smaller port may be the more economical choice. The 5 um element (W) suits circuits with finer components downstream; the standard grade is 40 um if 5 um is finer than the application needs. The automatic drain empties the aluminium bowl without operator attention - choose manual drain only where an operator is routinely present. This is the low-pressure regulator type; its exact adjustment range is not published in the material we hold, so confirm it with us before ordering if your set pressure is critical. The round gauge reads in bar; square embedded gauges and MPa or psi scales are the other catalogue options. NPT is the thread on this unit; PT and G (BSPP) are order options. Flow is published as curves, not a single rating - send us your application 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 GFR600 as curves, not as a single rated number, so we do not quote a figure that could mislead your sizing. Tell us your application - inlet pressure, downstream demand and acceptable pressure drop - and we will confirm the relevant curve and datasheet figures on request before you order.
Both are read directly from the model code. The A position selects the automatic drain, which empties the aluminium alloy bowl without an operator or a pressure differential, and the W selects the 5 um filter element instead of the 40 um standard grade. If your circuit does not need 5 um filtration, the 40 um version of the same frame is the catalogue alternative.
