The AirTAC GFR600C20ALJF2GK AirTAC Filter Regulator G3/4 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 GFR600C20ALJF2GK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G3/4 (BSPP) port, a 40 um standard filter element, an automatic drain that discharges collected condensate without manual attention, and a low-pressure regulator type. The embedded square gauge is fitted and reads in psi, a reverse/check valve is included, and the unit ships without a mounting bracket. The aluminium alloy bowl is the material used at size 600. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1", and with options including manual or automatic drain, a 5 um element (code W), gauge scale in MPa, psi or bar, and G or NPT thread variants. Flow figures for this series are published as curves rather than a single rated number, so ask us to confirm the datasheet and sizing 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.

Installed at the take-off point of a factory compressed-air ring main to remove condensate and pipe scale and hold a steady low pressure for the downstream distribution leg serving a production bay.
Feeding filtered, pressure-controlled air to the cylinders and actuators on a carton-forming and conveyor transfer line, where the automatic drain keeps the bowl clear through continuous shifts.
Mounted as the first conditioning stage in a machine's pneumatic control panel, delivering clean air at a set low pressure to directional valves and air-prepared sub-circuits, with the psi gauge giving a local setpoint readout.
Size and port set the capacity envelope: this is the largest GFR size (600) with a 3/4" port, chosen when the line demands the top of the range - step down to 200/300/400 with smaller ports for lighter duty. Drain type is a real choice: automatic (this unit) empties the bowl on its own, manual requires operator attention, and differential-pressure drain is the catalogue default. Filter grade is 40 um standard with 5 um (code W) where finer filtration is needed. The square gauge here reads psi; MPa or bar scales are available, and an external round gauge is optional. Thread is G (BSPP) on this code, with PT as the standard and NPT orderable - all as specification, not delivery terms. No mounting bracket is fitted (code J); a bracket can be specified where pipework support is needed. Because flow is published as curves rather than a single rating, 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 the GFR series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your line pressure and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code means the bowl drains itself: collected condensate is discharged automatically, so the unit suits unattended or continuously running installations where a manual drain could be forgotten. The L code marks the low-pressure regulator type, intended for applications controlled below the standard regulator range; the exact adjustment range for this low-pressure variant is not published in the catalogue, so we confirm it on request.
