The AirTAC GFR600C20ALJC2WGK AirTAC Filter Regulator 3/4 in G 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 GFR600C20ALJC2WGK 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 larger air lines, with a G3/4 (BSPP) port, a 5 um filter element (W grade, finer than the 40 um standard), an automatic drain that purges collected condensate without manual attention, and a low-pressure regulator type for applications that operate below standard regulator ranges. A round external gauge with a psi scale is fitted so line pressure can be read directly, and a reverse (check) valve is fitted to hold downstream pressure if the supply drops.
This is a genuine AirTAC part from the GFR600 series, the largest size in the G-series filter regulator line. The aluminium alloy bowl is specific to size 600 (smaller sizes use polycarbonate), and the unit works at up to 1.0 MPa (145 psi) inlet in temperatures from -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures against 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 from a factory 3/4 in air main, it filters water and particles from the supply and holds a steady low regulated pressure to the machines on that branch.
Feeding a bank of air-operated valves and actuators that run at reduced pressure, the low-pressure regulator type and fitted psi gauge let the set point be read and held at the actuator supply.
On a packaging or conveyor line with check-valve-sensitive circuits, the unit conditions the air to 5 um, drains condensate automatically between shifts, and the reverse valve holds downstream pressure through supply dips.
Size 600 with a 3/4 in port sits at the top of the G-series range, so step up to it when your line flow demands more than a 300 or 400 unit can pass - we can confirm the flow curve for your duty on request. The 5 um element (code W) suits downstream equipment sensitive to finer particles; choose the 40 um standard grade where general protection is enough. The automatic drain keeps condensate off your floor in attended or hard-to-reach installations; manual and differential-pressure drains are the alternatives in the family. The low-pressure (L) regulator type is the right pick when your working pressure sits below the standard range - its exact adjustment range is not published in the material we hold, so confirm it with us before ordering. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are the other catalogue options. Thread here is G (BSPP); PT is the standard offering and NPT is available to order. Note this configuration ships without a mounting bracket (code J) - brackets are optional on this family.
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 series as curves, not as a single rated figure, so we do not quote a number. Tell us your line size and demand and we will confirm the flow curve and sizing from the datasheet on request before you order.
The L code means this GFR600 carries the low-pressure regulator type, intended for circuits working below the standard regulator range; its exact adjustment range is not published in our material, so confirm it with us. The K code means a reverse (check) valve is fitted, which holds downstream pressure if the upstream supply is interrupted.
