The AirTAC GFR600C20LJC2WK AirTAC Filter Regulator PT3/4, 5 um 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 GFR600C20LJC2WK is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation in one body. This size 600 unit has PT3/4 ports, a 5 um filter element (the finer W grade), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a metal bowl (aluminium alloy at this size). It is built as the low-pressure type, carries a reverse/check valve, and is supplied without a mounting bracket. The external round gauge fitted here reads in psi.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with port options from 1/8 to 1 inch, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, gauge styles and scales, and PT, G or NPT threads. Max 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 and we will confirm the datasheet 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.

Conditioning and stepping down shop air ahead of paint spray guns on a finishing line, where the job is clean, dry air held at a reduced, stable setting rather than full line pressure.
A single conditioning point feeding carton sealers, case packers and palletiser grippers on a packaging line, filtering water and debris from the header and regulating pressure for the machine's valve train.
Bench and pilot-scale setups in a process plant where air must be filtered to 5 um and held at a low, repeatable pressure, with the check valve holding the setting against backflow from the rig.
Start with the port step: size 600 with PT3/4 suits lines plumbed at 3/4 inch; step down to 300 or 400 if your flow demand is smaller, since larger sizes carry larger ports and higher flow capacity. Choose the drain: differential-pressure (as here) needs no operator input, automatic drains on a timer-free basis, and manual drains suit infrequently visited installations. Pick 5 um (this unit) where downstream equipment is sensitive to fine particulate, or the standard 40 um for general supply. Gauge options are an embedded square gauge or an external round gauge, in MPa, psi or bar scales; this unit has a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT as order options; a J suffix deletes the bracket.
One honest note on sizing: AirTAC publishes flow for this family as curves, not a single rated figure, and the low-pressure type's regulation range is not stated on the sheet we hold. Tell us your line pressure, required downstream pressure and air demand, and we will confirm the datasheet figures 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 family as curves, not as a single rated number, so we do not quote a figure on the page. Send us your line pressure, target downstream pressure and air demand, and we will confirm the datasheet flow curve and sizing for your application on request.
The W is the filter-grade code: the GFR family is standard at 40 um, and W specifies the finer 5 um element for applications where downstream valves, cylinders or instruments need cleaner air. This unit also carries K (a reverse/check valve), C2 (an external round gauge reading in psi), L (the low-pressure regulator type) and J (no mounting bracket); its drain is the differential-pressure type.
