The AirTAC GFR600C20LJF1WTK 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 GFR600C20LJF1WTK is an AirTAC GFR600 filter regulator: water and particulate filtration and pressure regulation combined in one body, sized for a 3/4 in NPT port. This configuration carries the W-code 5 um filter element, a differential-pressure drain that removes condensate without a manual draining routine, the low-pressure regulator type, an embedded square gauge reading in MPa, and a reverse (check) valve per the K code. The size-600 bowl is aluminium alloy, and the unit is supplied without a mounting bracket (code J). 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 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, plus a choice of drain type, filter grade, gauge style and scale, and standard or low-pressure regulation. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures for this model 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.

Conditioning the 3/4 in main that feeds pneumatic clamps and fixtures on a machining centre: the 5 um element keeps particulate and water out of the directional valves, while the regulator holds the clamping pressure the cell program calls for and the check valve guards against reverse flow.
Supplying the sealing cylinders and small actuators on a food tray-sealing line, where the low-pressure regulator type suits gentler actuation settings and the 5 um filtration protects the machine's valves from condensate carryover and grit.
Point-of-use treatment at a spray booth drop: the 5 um element keeps water and particles out of the gun supply, and the regulator holds the atomising pressure set by the booth recipe, with the square MPa gauge giving the operator a direct readout.
Pick the GFR size and port against the air demand of your main: this unit is size 600 with a 3/4 in NPT port, the largest step in the family, where larger sizes mean a larger port and more flow. Because flow is published as curves and not a single rating, send us your line pressure and consumption and we will confirm sizing before you order. The remaining choices are all decodable from the code: drain type (differential-pressure as here, automatic with A, or manual with M), filter grade (40 um standard or 5 um with W, fitted here), gauge style and scale (embedded square gauge in MPa here; an external round gauge in MPa, psi or bar is optional), thread (PT is the standard, G and NPT are order options), bracket (omitted here with J), and the low-pressure regulator type selected in place of the standard regulator.
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 GFR600 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the flow and the full datasheet figures for this exact model on request.
This GFR600 carries the L code, so it is the low-pressure regulator variant rather than the standard type. The exact adjustment range for the low-pressure version is not published, and we will confirm it from the datasheet on request. Everything else decodes normally: 5 um filtration, differential-pressure drain, embedded square MPa gauge, fitted check valve and a 3/4 in NPT port.
