The AirTAC GFR600C20LJF3T AirTAC Filter Regulator NPT3/4 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 GFR600C20LJF3T is an AirTAC GFR filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size 600 unit carries a 3/4 in NPT port, a 40 um standard filter element, a differential-pressure drain and the low-pressure regulator type (L). The embedded square pressure gauge is fitted and reads in bar, and the J code means the mounting bracket is omitted. At size 600 the bowl is aluminium alloy.
It is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm 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.

Filtered, low-pressure regulated air to pneumatic clamps and swing cylinders on a machining centre, where a reduced regulated pressure protects the fixture and the workpiece.
Feeding heat-seal and tuck cylinders on a carton packaging line running at reduced regulated pressure, with water and pipe scale removed from the shop air before it reaches the valves.
Supplying clean, low-pressure regulated atomizing air to spray guns in a finishing booth, keeping moisture and particulates out of the coating.
Size and port step up together from 200 to 600; this unit sits at 3/4 in NPT, so pick the size whose flow curve covers your demand with margin. Drain options are differential-pressure (this unit, the default), automatic (A) or manual (M). Filter grade is 40 um standard here; specify W for the 5 um element. The gauge on this unit is the embedded square type reading in bar; MPa or psi scales and an external round gauge are order options. Thread: PT is the standard, with G and NPT as order options - this unit is NPT. The J code omits the mounting bracket. The regulator here is the low-pressure type (L); 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 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures for this unit on request.
The L code marks the low-pressure regulator variant of the GFR. Its exact adjustment range is not published in our data sheet, so confirm it with us before ordering. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
