The AirTAC GFR600C20MLJF2TK AirTAC Filter Regulator NPT3/4 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 GFR600C20MLJF2TK is a filter regulator: water and particulate removal plus pressure regulation in a single body. This size 600 unit has a 3/4 in NPT thread, a manual drain on an aluminium alloy bowl, a 40 um standard filter element, and a low-pressure regulator type. Maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), an embedded square gauge with a psi scale is fitted, a reverse/check valve (code K) is included, and no mounting bracket is supplied.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with PT, G or NPT threads, differential-pressure, automatic or manual drains, a 5 um element option (code W), gauge and scale choices, and optional brackets. Flow is published as curves rather than a single rating, and the set-pressure range of the low-pressure type is not listed in the catalogue - ask us and we will confirm both from the datasheet.

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 filtered, regulated air to the gripper and pusher cylinders on a beverage bottling line, with the low-pressure regulator holding a gentle set pressure for delicate container handling and the manual drain emptied at changeover.
Supplying clean, regulated air to the clamp circuits of a CNC machining cell, where the psi-scale square gauge gives operators a direct readout at the machine and the 40 um element protects the clamp valves.
Conditioning air for diverter and stopper cylinders along a packaging conveyor, with the 3/4 in port serving the larger main line feed and the manual drain cleared during scheduled line stops.
Size and port are the first decision: 200, 300, 400 and 600 step up in port and flow capacity, and this unit sits at the top of the range with a 3/4 in NPT thread, so match the size to the flow your line needs. Drain comes as differential-pressure (default), automatic (A) or manual (M, as here); manual suits installations that are checked on a schedule. Filter grade is 40 um standard or 5 um with code W. The gauge is an embedded square unit with MPa, psi or bar scales, and an external round gauge is optional. Thread is PT as standard with G and NPT as order options, and a bracket can be added where this configuration omits one. Because flow is published as curves and not a single rating, send us your application 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 GFR600 as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow curve and correct sizing from the datasheet on request.
This configuration uses a manual drain (code M): condensate is released by hand during checks or changeovers. The same size 600 unit is also available with the differential-pressure drain (default) or an automatic drain (code A) if you prefer unattended draining - order the corresponding code.
