The AirTAC GFR600C20ALJC3WTK AirTAC Filter Regulator NPT 3/4 in 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 GFR600C20ALJC3WTK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This 600-size unit is built for 3/4 in NPT ports, carries a 5 um filter element (the W grade, finer than the 40 um standard), and drains its bowl automatically, so collected condensate is expelled without manual attention. It is the low-pressure (L) type, and the code specifies a round pressure gauge reading in bar. A reverse/check valve is fitted and the unit is supplied without a mounting bracket. The size-600 bowl is aluminium alloy. 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 in to 1 in, and options across drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale, PT, G or NPT threads, brackets, and low-pressure or standard regulator types. AirTAC publishes flow for this family as curves rather than a single rating, so we confirm flow and other datasheet figures 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.

Feeding clean, regulated air to carton-sealers and wrapping heads on a packaging line, where the 5 um element helps keep water and fine debris out of downstream valves and cylinders.
Supplying weld and assembly clamping circuits that hold a set pressure through the shift; the fitted reverse/check valve supports the circuit between cycles on a 3/4 in supply main.
Air preparation for spray guns and coating lines, where the finer 5 um grade and automatic bowl draining keep moisture and particles out of the finish without daily bowl checks.
Choose the size step by the air your circuit needs: 600 is the largest G-series size and takes a 3/4 in port, so step down to 300 or 400 for smaller circuits - and ask us to check the published flow curves against your demand before ordering. Drain choice matters: this unit drains automatically, which suits unattended installations, while manual and differential-pressure drains are available in the same family. Filter grade is 5 um here; the 40 um standard element is the alternative when finer filtration is not required. The gauge on this code is a round dial in bar; embedded square gauges and MPa or psi scales are the other options. Thread is NPT as coded, PT is the standard, and G (BSPP) is also orderable. This configuration has no mounting bracket - select a bracket variant if you wall- or panel-mount.
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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the flow from the datasheet for this 600-size, 3/4 in unit before you order.
This code carries the A drain option: the bowl expels collected condensate automatically, which suits installations that are not checked daily. The same GFR600 body is available with a manual drain or the differential-pressure default, and with the 40 um standard element instead of the 5 um (W) grade fitted here.
