The AirTAC GFR600C20LJC1WTK 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.
GFR600C20LJC1WTK is an AirTAC GFR600 filter regulator: one body removes water and particulate from compressed air and regulates downstream pressure. This configuration is built for 3/4 in NPT ports, carries the 5 um filtration element (code W) in place of the 40 um standard, and is the low-pressure regulator type (code L). It uses the differential-pressure drain, has a round MPa pressure gauge fitted (code C1) and a reverse/check valve (code K), and is supplied without a mounting bracket (code J).
This is a genuine AirTAC part. The G-series filter regulator line spans sizes 200, 300, 400 and 600 with ports from 1/8 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 MPa/psi/bar scale. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing figures 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.

A 3/4 in filter regulator feeding spray guns and atomising headers on a paint or coating line: the 5 um element keeps finer particles away from the nozzles, and the low-pressure regulator type is intended for circuits that run at reduced pressure.
Supplying fixture clamps and swing cylinders on an automated assembly station: one body filters the air and regulates the pressure the clamps were set up for, with the fitted reverse/check valve part of this configuration.
A 3/4 in NPT feed for air cylinders and actuators along a packaging or bottling conveyor: water and particulate are stripped out before the actuators, and the regulator holds their operating pressure steady across the line.
Size and port are the first decodable choices: 600 is the largest size in the G-series and this unit takes a 3/4 in NPT port, so step up from 200/300/400 according to the air demand of the line. This model is already configured with the 5 um element (W) instead of the 40 um standard, the low-pressure regulator type (L), a round MPa gauge (C1), a reverse/check valve (K), no bracket (J) and NPT thread (T); the differential-pressure drain is the default. Thread can alternatively be ordered as PT (standard) or G (BSPP), and drain type, bracket, gauge style and MPa/psi/bar scale are all catalogue options. Because published flow data is a set of curves rather than one rated figure, send us your application conditions and we will confirm sizing and 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 G-series flow as performance curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and the flow your equipment needs, and we will confirm the datasheet curve and correct sizing for GFR600C20LJC1WTK before you order.
The L code marks the low-pressure regulator variant, intended for circuits that run at reduced pressure rather than the standard adjustment band. The exact adjustment range for this variant is not published in our data, so we confirm it on request. The unit otherwise carries the standard GFR600 specification, including a 1.0 MPa (145 psi) maximum inlet pressure and a -5 to 70 C operating range.
