The AirTAC GFR600C20LJC2WT 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 AirTAC GFR600C20LJC2WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 3/4 in NPT port, 5 um filtration (the fine W grade, versus the standard 40 um), a differential-pressure drain that bleeds condensate automatically as flow passes through, and the low-pressure regulator type for circuits that run at reduced setpoints. An external round gauge on a psi scale is fitted so operators can read and adjust the outlet setting directly, and the metal bowl (aluminium alloy at size 600) suits duties where a polycarbonate bowl is not preferred. 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 port sizes from 1/8 in to 1 in, and can be ordered with manual, automatic or differential-pressure drains, 40 um or 5 um filtration, square or round gauges on MPa, psi or bar scales, a reverse/check valve, and G, NPT or PT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application before ordering.

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.

Installed at the 3/4 in take-off feeding a packaging hall's distribution run, it strips water and fine particles from the main supply and holds a reduced, stable pressure for the machines downstream, with the psi gauge giving operators a visible setpoint.
Mounted ahead of the air jets and actuator bank on a bottling-line conveyor, the 5 um element protects the small jets and valve spools from condensate carryover while the low-pressure regulator holds the gentle setting the nozzles need.
Fitted on the supply header serving quarter-turn pneumatic actuators in a process skid, it delivers clean, regulated air to the positioners and solenoid valves, with the differential-pressure drain keeping condensate out of the actuator tubing without daily manual draining.
Start with the port: this unit steps up to 3/4 in NPT in the largest GFR frame, the choice driven by the air demand of the circuit rather than line size alone. Filtration here is the 5 um W grade - pick it when downstream valves, cylinders or instruments need finer protection than the standard 40 um element. Drain choice matters: differential-pressure (as fitted here) needs no operator attention, automatic drains cycle on their own, and manual drains suit supervised installations. The low-pressure regulator type is the right pick for circuits running at reduced setpoints; confirm the exact adjustment range with us, as it is not published in the standard tables. Gauge scales can be MPa, psi or bar, threads can be PT, G or NPT, and a mounting bracket can be added if the unit will not sit directly on a manifold or wall plate. Because flow for this series is published as curves rather than a single rating, ask us to confirm 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 flow for the GFR series as performance curves rather than a single rated figure, so we do not quote one number here. Tell us your inlet pressure, setpoint and expected air demand, and we will confirm the sizing against the datasheet curves for this exact model before you order.
The W in the code specifies the 5 um element instead of the standard 40 um grade, giving finer protection for downstream valves, cylinders and instruments. The blank drain position means the differential-pressure type: condensate is discharged automatically as air flows through, so no manual draining routine is needed. If you prefer a fully automatic or a manual drain, that is an orderable option in the same size.
