The AirTAC GFR600C20ALJF2WG AirTAC Filter Regulator G3/4 5 um 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 GFR600C20ALJF2WG is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for a 3/4 in port with G (BSPP) thread, 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 need manual bleeding during operation. It is the low-pressure type (code L) for circuits that run below standard regulating ranges, and it ships with the embedded square gauge scaled in psi. No reverse/check valve is fitted and no mounting bracket is included. The size-600 bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, gauge scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures for 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.

Feeds spray-booth and coating lines that run at reduced working pressures, where the low-pressure regulator type holds a gentler setting and the 5 um element keeps fine overspray-critical air clean.
Serves the fixture-clamping circuit of a CNC cell: the filter stage strips water and chips-laden particulate before the regulator sets a stable clamp pressure, and the psi gauge lets setters verify the setting at a glance.
Placed ahead of a packaging-line conveyor's air-knife header, it filters the supply to 5 um and regulates the low header pressure the knives need, while the automatic drain clears condensate without operator attention.
Size 600 with a 3/4 in port is the largest step in the GFR line, so start there when your line's flow demand sits above what a 1/2 in unit can pass; work down to 400/300/200 as demand falls. Because flow is published as curves and not a single rating, send us your application's flow and pressure targets and we will confirm sizing against the datasheet before you order. This unit is the low-pressure type (L), suited to circuits that operate below standard regulating ranges; the exact regulating window for this variant is not published, so confirm it with us. The 5 um element (W) suits downstream equipment that needs finer protection than the 40 um standard grade; choose 40 um where coarser, longer-life filtration is acceptable. The automatic drain (A) suits unattended or hard-to-reach installations; manual (M) or differential-pressure drains are available on other configurations. The fitted square gauge reads in psi (scale 2); MPa or bar scales and an external round gauge are options. Thread here is G (BSPP); PT is the standard thread and G or NPT are order options. No bracket is included with the J code, so plan your own mounting.
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 rather than a single rated figure, so we do not quote one number. Tell us your required flow and working pressure and we will confirm sizing against the datasheet on request before you order.
The L code makes this a low-pressure regulator variant, intended for circuits that run below standard regulating ranges; the exact regulating window for this variant is not published, so confirm it with us. The A code gives an automatic drain that expels collected condensate from the aluminium alloy bowl without manual bleeding, and the W code fits the finer 5 um element instead of the 40 um standard grade.
