The AirTAC GFR600C20LJF1TK 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 GFR600C20LJF1TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in one body. This 600-size unit is threaded NPT3/4 (3/4 in), carries the standard 40 um filter element, and drains collected condensate by the differential-pressure method. The regulator is the low-pressure type (code L), an embedded square gauge scaled in MPa is fitted, and a reverse (check) valve is built in. The mounting bracket is deleted (code J), and the size-600 bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options that include 5 um filtration (code W), automatic or manual drains, psi or bar gauge scales, G (BSPP) or NPT threads, and a mounting bracket. 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 sizing and the datasheet 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.

Filtered, regulated air to the actuation circuits of a mechanical stamping press, with the built-in check valve blocking backflow toward the supply side.
Point-of-use filtration and low-pressure regulation ahead of spray guns in a paint booth, with the 40 um element catching pipe scale and the bowl collecting condensate.
Regulated air to the gripper and pusher cylinders on a beverage bottling conveyor, with the fitted MPa gauge giving operators a local setpoint reference.
Size and port step up with flow demand: sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch; this unit is 600 size on a 3/4 in NPT port. Drain choice is 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 embedded square gauge on this unit is scaled in MPa; psi (2) and bar (3) scales and an external round gauge are order options. Thread: PT is the AirTAC standard, while G (BSPP) and NPT (this unit) are catalogue options to order. The J code deletes the mounting bracket; omit J to include one. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm the right size 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 filter-regulator flow as curves, not as a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm sizing against the datasheet on request.
L designates the low-pressure type of regulator, a variant for applications regulated at lower pressures than the standard type. The exact adjust range for this low-pressure variant is not published in the catalogue sheet we use, so we confirm it on request. The rest of the code decodes as: NPT3/4 port, 40 um element, differential-pressure drain, square MPa gauge, check valve fitted, no bracket.
