The AirTAC GFR600C20LJF2G AirTAC Filter Regulator G3/4, Low-Pressure 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 GFR600C20LJF2G is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This size 600 unit carries a G3/4 (3/4 in) female G-thread port, is built as the low-pressure regulator type, filters to the standard 40 um grade, and uses a differential-pressure drain that bleeds condensate automatically whenever the pressure differential across the element is high enough. The size 600 bowl is aluminium alloy, an embedded square gauge with psi scale is fitted, and no mounting bracket and no reverse/check valve are included in this configuration.
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, a choice of differential-pressure, automatic or manual drains, a 5 um optional element (code W), MPa, psi or bar gauge scales, and PT, G or NPT threads. Maximum 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 to confirm sizing figures from the datasheet 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.

On a palletiser line running large bore cylinders and grippers, this G3/4 filter regulator conditions the main supply: the 40 um element strips water and pipe scale, and the low-pressure regulator holds a gentle, stable working pressure so cartons are clamped without crushing.
A washdown-adjacent bottling hall feeds stoppers, pushers and gate diverters from a 3/4 in ring main. This unit filters the humid plant air at the drop and regulates it down to the low pressure the conveyor actuators need, with the differential-pressure drain collecting condensate along the way.
A leak-test and pressure-test bench drawing from shop air uses this filter regulator at its G3/4 inlet to deliver clean, low-pressure air to the fixture circuit, with the fitted psi gauge giving the operator a direct readout of the regulated setpoint.
Start with the port step: this unit is size 600 with a G3/4 (3/4 in) G-thread port, the largest in the GFR range - step down to sizes 200/300/400 if your circuit uses smaller ports, and match the size to the flow your line needs. Choose the drain next: this configuration uses the differential-pressure drain (default); specify automatic (A) for continuous condensate removal or manual (M) where you want to drain on a schedule. Filtration is the standard 40 um element; add code W for the 5 um grade if downstream valves or instruments need finer air. This is the low-pressure regulator type, so its exact adjustment range differs from the standard type - confirm the range with us before ordering if your setpoint is critical. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are alternatives. Threads come as PT (standard), G or NPT to order, and a mounting bracket can be added. Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing from 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Tell us your line pressure, setpoint and the flow your actuators need, and we will confirm the correct size against the datasheet curves on request.
The L in the code marks the low-pressure regulator variant, intended where the working setpoint sits below what the standard type is set up for. Its exact adjustment range is not published in the catalogue sheet we work from, so confirm your setpoint with us and we will verify the range from the datasheet before you order. The standard GFR type is available as an alternative.
