The AirTAC GFR600C20ALJF1WTK 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 AirTAC GFR600C20ALJF1WTK is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is built around a 3/4 in NPT port, a fine 5 um filter element (code W), and an automatic drain that bleeds collected condensate from the bowl without manual attention. The size-600 bowl is aluminium alloy, and the low-pressure regulator type (code L) is intended for circuits that run below standard shop-air pressures. A square pressure gauge is fitted (MPa scale), a reverse/check valve is installed, and the unit ships without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT/G/NPT thread choices, 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, gauge and scale options, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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 a plant-air header that runs below standard shop pressure: the low-pressure regulator type holds the reduced setting while the 5 um element strips water and scale before the distribution take-offs.
Conditioning the 3/4 in main feed to an assembly line's valve manifolds: filtration and regulation in one body, with the automatic drain keeping condensate out of the circuit during unattended shifts.
Supplying the air cylinders and clamps on a conveyor system: the reverse/check valve holds downstream pressure if the supply dips, and the fitted gauge lets operators verify setpoint at a glance.
Size and port set the capacity envelope: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range - step down to 200/300/400 if your line is smaller. Drain type is a real choice: differential-pressure (default), automatic (this unit), or manual. Filter grade is 40 um standard or 5 um fine (W, fitted here) - choose 5 um where downstream valves and cylinders need cleaner air. Gauges are square (fitted, MPa here) or optional round, with MPa, psi or bar scales; thread is PT standard with G and NPT as order options; brackets are optional (not fitted here). Flow for this family 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 this family as performance curves rather than a single rated figure, so no single number is quoted here. Contact us with your application details and we will confirm the datasheet and sizing figures on request.
The automatic drain (code A) vents collected condensate from the bowl on its own, which suits unattended or hard-to-reach installations. The GFR family also offers the differential-pressure drain (default) and a manual drain (code M) where you prefer operator-controlled bleeding.
