The AirTAC GFR600C20ALJC2TK AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20ALJC2TK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 600 unit is built with a 3/4 in NPT port, a 40 um standard filter element and an automatic drain that bleeds collected condensate from the bowl without manual attention. It is the low-pressure regulator type, fitted with an external round gauge reading in psi, and a reverse/check valve is incorporated. The metal bowl on this size 600 unit is aluminium alloy, and max 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. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of drain type (differential-pressure, automatic or manual), an optional 5 um filter element (code W), gauge style and scale, PT/G/NPT threads and bracket choices. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

Installed on a 3/4 in compressed-air drop feeding a production department, it cleans water and scale out of the supply and holds a steady low-pressure setting for the tools and cylinders downstream, with the automatic drain keeping the aluminium bowl clear of condensate.
Mounted ahead of air-over-oil presses or clamping fixtures that run at reduced pressure, it filters the incoming air and regulates the working pressure, while the reverse/check valve helps hold the set pressure if the upstream supply dips.
Fitted at the feed point of a packaging or conveyor line using air jets, actuators and blow-off nozzles, it removes moisture and particles that would gum valves and nozzles and supplies them at a controlled low-pressure setting read locally on the psi gauge.
Size 600 with a 3/4 in NPT port is the large-flow step of the GFR range; step up or down through sizes 200/300/400/600 to match the line size and air demand of the machine it feeds. This unit pairs an automatic drain (no daily bowl draining needed) with the 40 um standard element; if finer filtration is required, the 5 um W-grade element is the catalogue option. The round psi gauge is fitted here; embedded square gauges and MPa or bar scales are the alternative choices. PT is the standard thread and G (BSPP) or NPT are order options - this code is built with NPT. No mounting bracket is included on this configuration. Because flow is published as curves rather than one rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
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, not as a single rated number, so we do not quote a flow figure for this unit. Send us your line size and air demand and we will confirm the sizing against the datasheet on request before you order.
The code C2 in GFR600C20ALJC2TK specifies the optional external round gauge with a psi scale (the embedded square gauge is the standard alternative, with MPa or bar scales available), and the A specifies the automatic drain, which expels collected condensate from the aluminium alloy bowl by itself instead of relying on manual or differential-pressure draining.
