The AirTAC GFR60020LJC2WGK AirTAC Filter Regulator G3/4 Low-Pressure is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" 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 GFR60020LJC2WGK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size-600 unit is built with a G3/4 (BSPP) port, a 5 um filter element (code W, finer than the 40 um standard), and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. It is the low-pressure (L) type, so it is intended for applications that hold a lower regulated set-point than the standard version; the exact adjustment range for this type is not published in the catalogue and we confirm it on request. A round pressure gauge scaled in psi is fitted, a reverse/check valve is included, and the aluminium alloy bowl suits the size-600 frame. No mounting bracket is supplied with this code.
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, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, gauge and scale options, G/NPT thread variants and bracket choices. 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 rated figure, so ask us to confirm flow or any datasheet figure against 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 a 3/4 in branch off the compressor ring main, the unit strips water and fine particulate from the shop air and holds a stable low regulated supply to the machines fed from that drop, with the psi gauge giving a local set-point readout.
Mounted ahead of a bank of air-operated valves and actuators, the 5 um element protects valve seats and seals from condensate and fine debris while the low-pressure regulation holds the supply at the lower set-point those actuators are specified for.
Feeding the cylinder circuits of a packaging or conveyor line, the filter-regulator keeps line-borne water out of the cylinders and lets the line supervisor set and read the working pressure in psi at the unit, with the check valve holding the circuit if upstream supply dips.
Start with the port step: this is the size-600 frame with a G3/4 port, the largest in the GFR range, chosen when the main air supply is 3/4 in and the machine demand is at the top of the family's flow span. Match the drain to how the unit will be serviced: differential-pressure (as coded here) drains itself during operation, automatic (A) drains on a cycle, and manual (M) is emptied by hand. This code carries the 5 um element (W) for finer particulate removal; the 40 um element is the standard alternative. The round gauge fitted here is scaled in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is G (BSPP) as coded, with PT as the standard and NPT available to order, and this code omits the mounting bracket (J) where one is not needed. Because flow is published as curves and not a single rating, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line pressure, port size and air demand and we will confirm the sizing from the datasheet flow curves on request before you order.
This code carries the L (low-pressure) regulator type, and the catalogue does not publish an exact adjustment range for that type in the GFR series. We confirm the range on request. The drain on this unit is differential-pressure, which discharges collected condensate automatically as the pressure differential across the 5 um element rises, so no manual draining routine is needed.
