The AirTAC GFR600C20MLJC2K AirTAC Low-Pressure Filter Regulator PT3/4 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 GFR600C20MLJC2K is a GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built on a 3/4 in PT port with a metal bowl (aluminium alloy at size 600), a manual drain, the standard 40 um filter element, and the low-pressure regulator type. It includes a round external gauge scaled in psi and a reverse/check valve, and omits the mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, a 5 um element option (code W), embedded square or external round gauges scaled in MPa, psi or bar, G (BSPP) and NPT thread options, and bracket choices. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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.

Filtering shop air and stepping it down to the reduced, stable pressure that low-pressure clamping and hold-down cylinders on an assembly fixture need, with the fitted reverse/check valve in the circuit and the round psi gauge for direct setting.
Conditioning compressed air for a finishing line's low-pressure spray guns and atomizing nozzles, where water and particulate must be removed and the air held at a gentle, repeatable pressure read directly off the psi gauge.
A filtered, regulated drop feeding control valves and small actuators on a machine's pneumatic manifold, with the 3/4 in PT connection suiting a main panel feed and the round psi gauge giving an at-a-glance setpoint.
Choose the size by port and required flow: this unit is size 600 with a 3/4 in PT port, the largest step in the family, while sizes 200/300/400 suit lighter duties. Drain type is a real choice - this code specifies a manual drain, so an operator drains the bowl; automatic and differential-pressure drains are available where unattended drainage is preferred. The filter grade here is the standard 40 um element; specify W for the 5 um grade where finer filtration is required. The gauge fitted is the external round type with a psi scale; an embedded square gauge, or MPa/bar scales, are the alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and this configuration omits the mounting bracket. The regulator is the low-pressure type; its exact adjustment range is not published, so confirm it with us before ordering. Flow is published as curves, not a single rating - ask us to confirm sizing against your application 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 GFR600 as curves, not as a single rated figure, so we do not quote a number here. Ask us and we will confirm the datasheet flow curve against your required flow and working pressure before you order.
The L position selects the low-pressure regulator type instead of the standard one, so this unit is intended for duties that call for reduced regulated pressures. The exact adjustment range of the low-pressure version is not published on the sheet we work from, so please confirm the range with us. The rest of the decode is standard: manual drain, 40 um element, round psi gauge, reverse/check valve fitted and no bracket.
