The AirTAC GFR600C20ALC2GK AirTAC Filter Regulator G3/4, Low-Pressure 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 GFR600C20ALC2GK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit carries a G3/4 (BSPP) port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and the low-pressure regulator type for duty where supply pressure must be set well below line pressure. The build includes a round external gauge scaled in psi, a reverse/check valve, an included mounting bracket, and an aluminium alloy bowl - the bowl material used at size 600. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, plus a choice of drain type, 40 um or 5 um (code W) filtration, gauge style and scale, and bracket or no-bracket (J) builds. AirTAC publishes flow for this series as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure 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.

At a plant-air drop feeding a low-pressure actuation zone - clamping fixtures, air tables or gate cylinders that run well below header pressure - the GFR600C20ALC2GK filters the supply and holds the reduced setting, with the automatic drain clearing condensate on its own.
On a packaging or bottling conveyor, stopper and pusher cylinders need clean air at a steady reduced pressure; this size-600 unit with G3/4 porting sits at the drop to condition and regulate that branch, and the psi gauge gives operators a direct reading.
For a bank of pneumatically actuated process valves, a stable, filtered pilot supply protects positioners and actuators; the 40 um element removes particulate and water, the low-pressure regulator sets the pilot level, and a reverse/check valve is fitted as part of this build.
The real, decodable choices on this family: step the size (200/300/400/600) and port (1/8 to 1 inch) against the flow your line needs; pick the drain type - differential-pressure (the default when no drain letter appears), automatic (as fitted here, code A) or manual (code M); choose the filter grade, 40 um standard or 5 um with code W; select gauge style and scale (embedded square gauge standard, external round gauge optional, MPa/psi/bar); set the thread, PT standard with G and NPT as order options; and decide bracket or no-bracket (J). This unit is the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us. Flow is published as curves, not a single rating - ask us to check the curve 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 the GFR series as curves, not as a single rated figure, so we do not quote a number. Tell us your operating pressure and the flow your application needs, and we will confirm the sizing from the datasheet curves on request.
This unit carries code A - an automatic drain that ejects collected condensate without manual attention. The family also offers the differential-pressure drain (the default when no drain letter appears) and a manual drain (code M). The drain letter is part of the model code, so specify the type you want when ordering.
