The AirTAC GFR600C20C3WTK AirTAC Filter Regulator NPT 3/4in 5um 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 GFR600C20C3WTK is an AirTAC GFR600 filter regulator: a 600-size unit that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in NPT port, a 5 um filter element (the finer of the two published grades), a differential-pressure drain, a round pressure gauge with bar scale, a built-in reverse (check) valve, and a mounting bracket. The metal bowl on this 600 size is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes, with 40 um standard or 5 um (W) filtration, a choice of differential-pressure, automatic or manual drains, gauge and scale options, 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.

Point-of-use preparation on the 3/4 in main drop feeding a CNC machining cell: the 5 um element strips water and fine particulate from shop air before it reaches fixtures, clamps and tool-change cylinders, while the regulator holds a steady downstream setting.
Supply conditioning for the pneumatic header on a bottling or filling line, where gripper and valve actuators need clean, pressure-stable air; the differential-pressure drain clears collected condensate from the aluminium bowl without a manual blow-down stop.
Air preparation for gating and diverting cylinders along a conveyor system: the fitted reverse (check) valve helps hold the regulated downstream pressure through brief upstream dips, so gate cylinders do not sag mid-cycle.
Size and port are the first choice: 200, 300, 400 and 600 step up in port size and flow capacity, so match the size step to the air demand of the circuit rather than to the pipe alone. This unit is already specified with the finer 5 um element instead of the 40 um standard, a differential-pressure drain (the default, which bleeds the bowl automatically as pressure differential builds), a round gauge on the bar scale, and a reverse (check) valve that holds the downstream setting if upstream pressure dips. Thread is NPT here; PT is the standard and G is also a catalogue option. A bracket is included. Flow is published as curves, not a single rating, so 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your required flow and downstream pressure and we will confirm the sizing from the datasheet before you order.
The W code in the model selects the finer 5 um filter grade, versus the 40 um standard. Choose 5 um where downstream valves, actuators or processes need finer protection; both grades are published options across the GFR range, and the rest of the specification is unchanged.
