The AirTAC GFR600C20LJC2G 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 AirTAC GFR600C20LJC2G is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a G3/4 port, the standard 40 um filter element and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough. The regulator is the low-pressure type, and the fitted external round gauge reads in psi so the setting can be watched directly at the unit. The size 600 bowl is aluminium alloy, and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Packaging lines often run clamp and hold-down cylinders at reduced pressure to avoid crushing cartons. A filter regulator at each station cleans the supply and lets an operator set and watch the working pressure on the psi gauge.
Conveyor gating, stopping and diverting cylinders need clean, dry air and a stable, moderate pressure setting. A GFR unit mounted at the line drop conditions the supply and holds the setting, with the differential drain handling condensate in continuous duty.
Process and test benches that tap a high-pressure header for a low-pressure duty need filtration plus a regulator that behaves in the low-pressure band. This unit filters the take-off and lets the technician dial in the set point while reading it on the round gauge.
Start with the port: this unit is G3/4 on the size 600 body, the largest step in the GFR range, so match it to your line size and required air demand. Choose the drain to suit access: differential-pressure (as here) needs no attention at normal duty, automatic drains continuously, and manual suits infrequently visited installations. Filtration is 40 um standard (this code) or 5 um with code W where finer protection is needed. The round psi gauge fitted here is one option alongside the embedded square gauge, with MPa, psi or bar scales. PT is the standard thread; G and NPT are catalogue options to order. Brackets are optional on GFR, and this code is supplied without one. Because flow 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 curves, not as a single rated figure, so we do not quote a number here. Tell us your line size and air demand and we will confirm the flow figures from the datasheet for this exact model before you order.
This code is the low-pressure (L) version of the GFR600, so its adjustment band differs from the standard type and the exact range is not published in the material we hold. We will confirm the setting range from the datasheet on request. The unit itself takes up to 1.0 MPa (145 psi) inlet and works from -5 to 70 C, non-freezing.
