The AirTAC GFR600C20ALC2WTK 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 GFR600C20ALC2WTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure. This 600-size unit carries 3/4 in NPT threads, a 5 um filter element (code W), an automatic drain, a low-pressure regulator, an external round gauge on the psi scale and a reverse/check valve. The metal bowl fitted at size 600 is aluminium alloy, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and offers drain, filter-grade, gauge, thread and reverse-valve options across the range. AirTAC publishes flow as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application on request.

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 3/4 in air drop feeding a carton-closing and case-sealing line, it cleans the supply to 5 um and holds a steady low-pressure setting for the seal and clamp cylinders, with the automatic drain clearing condensate from the aluminium bowl.
Mounted on the branch feeding diverter gates, stoppers and pusher cylinders along a conveyor system, it filters incoming plant air and regulates it to the pressure the gate actuators were designed for, while the check valve holds the set circuit if supply dips.
Used on a laboratory or pilot-plant air bench running at reduced pressure, the low-pressure regulator type suits circuits that never see full line pressure, with the round psi gauge giving a direct read in the units the test procedure specifies.
Every choice in the GFR line is decodable from the code: size 200/300/400/600 sets the port and the flow capacity step; the drain is differential-pressure (default), automatic or manual; the filter grade is 40 um standard or 5 um (W); the gauge is the embedded square type or an external round gauge with MPa, psi or bar scale; the thread is PT as standard with G and NPT as order options; and J deletes the bracket. This configuration is 600 size on NPT3/4, 5 um grade, automatic drain, low-pressure regulator type, round psi gauge and a fitted check valve. Match the size step to the flow your line needs, choose the 5 um element where downstream valves and instruments demand cleaner air, and pick the automatic drain where condensate load makes manual draining impractical. The exact adjustment range of the low-pressure type is not published, and flow is published as curves rather than a single rating - ask us to confirm both 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 this family as curves, not as a single rated figure, so we do not quote a flow number, Cv or SCFM value. Tell us your application and we will confirm the datasheet curve and check the 600-size unit against your required flow on request before you order.
The A in the code specifies an automatic drain, which expels collected condensate from the bowl without anyone opening it - useful on lines that run unattended or carry a heavy water load. The GFR family also offers a manual drain (code M) and a differential-pressure drain as the default, so you can order the drain style that matches your maintenance routine.
