The AirTAC GFR600C20ALJC2GK 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 AirTAC GFR600C20ALJC2GK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit carries a G3/4 (BSPP) port, the largest port step in the GFR range, and is set up for automatic drain, so collected condensate is expelled without manual attention. The 40 um standard filter element handles general-purpose air preparation, the low-pressure regulator type is intended where lower controlled pressures are needed, and the fitted round gauge reads in psi. A reverse/check valve is fitted, and the metal bowl on this 600 size is aluminium alloy. No mounting bracket is included in this configuration.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and is available with manual, automatic or differential-pressure drains, a 5 um (W) filter element option, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Because flow is published as curves rather than a single rating, we confirm flow and datasheet 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 grip and lift cylinders on a beverage bottling line, where filtered, regulated air at a stable low setpoint keeps container handling repeatable through a full shift.
Supplying clamp cylinders on a CNC milling fixture, with the 40 um element protecting the clamp valve and the low-pressure regulator holding the clamping force setpoint.
Running divertor and stopper actuators on a carton packaging conveyor, where automatic drain handles condensate from a long supply run without daily operator attention.
Start with the port step: size 600 with a G3/4 port is the right choice when the supply line and expected air demand sit at the top of the GFR range; smaller sizes 200-400 step down through 1/8 to 3/4 inch ports. Drain choice matters in daily operation: this unit has an automatic drain, which suits unattended or hard-to-reach installations, while manual and differential-pressure drains are the other catalogue options. The 40 um element fitted here is the standard grade; specify the W code if the application needs the 5 um optional element. The fitted round gauge reads psi; square embedded gauges and MPa or bar scales are the alternatives. Thread is G (BSPP) here, with PT standard and NPT available to order, and brackets are optional (this configuration has none).
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, 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 the GFR family as curves rather than a single rated number, so there is no one rated flow figure we can quote. Tell us your line pressure and the air demand of the equipment downstream, and we will confirm the sizing from the datasheet on request.
The L code marks the low-pressure regulator variant, intended for applications controlled below the standard regulator range. The exact adjustment range for the low-pressure type is not published in the catalogue sheet we work from, so we confirm the range for your setpoint on request. Max inlet pressure is 1.0 MPa (145 psi) and the operating temperature is -5 to 70 C, non-freezing.
