The AirTAC GFR600C20LJF3TK AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20LJF3TK is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 unit is specified with a 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain, a low-pressure regulator type, an embedded square gauge scaled in bar, and a reverse/check valve fitted. The maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of ports, PT, G or NPT threads, differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) filter element, standard or low-pressure regulator types, gauge or no gauge, and with or without a reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so we confirm flow and datasheet figures 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 filtered, pressure-controlled air to carton sealers and wrap stations on a packaging line, where the low-pressure regulator type and bar-scaled square gauge suit a modest controlled output set at the machine.
Supplying actuated diverters, stops and gate cylinders along a conveyor run, with the reverse/check valve holding the downstream circuit if the upstream supply drops and the differential-pressure drain clearing condensate picked up on long runs.
Conditioning the air feed to quarter-turn pneumatic actuator panels on a process skid, where the 40 um element protects pilot valves and the NPT 3/4 in port matches the skid's actuation supply header.
Size 600 with a 3/4 in port is the largest step in the GFR range, so size the unit against the air demand of the line rather than the pipe size alone. This configuration carries the standard 40 um element (choose 5 um, code W, where finer particulate capture is needed) and a differential-pressure drain, which bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough. The low-pressure regulator type is intended where controlled output sits below the standard range; its exact adjustment range is not published, so confirm it against your setpoint before ordering. The square gauge is scaled in bar (MPa and psi scales are also available), and the fitted reverse/check valve holds downstream pressure if the upstream supply is lost. PT is the standard thread; G and NPT are catalogue order options, and this unit is ordered in NPT. A mounting bracket is not included with this code.
Flow for the GFR series is published as curves, not as a single rated number, so send us your application details 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 GFR series as curves rather than a single rated figure, so there is no one rated flow number to quote. Send us your application details and we will confirm the flow figures from the datasheet on request before you order.
The L in the code marks the low-pressure regulator type, intended for controlled outputs below the standard range. The exact adjustment range for the low-pressure type is not published in the material we hold, so confirm your setpoint with us and we will verify it against the datasheet before ordering.
