The AirTAC GFR600C20LJC2GK 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 GFR600C20LJC2GK is a filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a drain bowl but no lubricator. This size 600 unit carries a G3/4 port, the low-pressure regulator type, a 40 um standard filter element and a differential-pressure drain, which discharges condensate in normal service without manual attention. It is supplied with a round gauge reading in psi, a reverse (check) valve is fitted, and no mounting bracket is included. At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include a 5 um filter element (code W), automatic or manual drains, square or round gauges with MPa, psi or bar scales, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, 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.

| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

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.

Feeds filtered, regulated air to the clamp cylinders on a welding or assembly fixture, holding a stable low set pressure so clamping force stays repeatable across the shift.
Sits at the drop to a coating line's air supply, removing water and pipe scale from the compressed air while the low-pressure type regulator holds the gentler setting the atomising equipment needs.
Regulates air to the pick-and-place and sealing actuators on a carton or blister line, with the fitted check valve blocking backflow through the unit.
The real choices in this family are the size and port step, the drain type, the filter grade, the gauge and its scale, the thread and the bracket. Step up from 200 through 600 as your flow demand outgrows the smaller ports - this unit is already at the top of the range with its G3/4 port. The 40 um element is standard; choose 5 um (code W) where finer particulate removal matters. Drain options are differential-pressure (fitted here), automatic or manual. The round gauge on this code reads in psi; the embedded square gauge and MPa or bar scales are the alternatives. PT is the standard thread, with G and NPT available to order, and brackets are optional - none is fitted on this code. 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. Send us your application details and we will confirm the datasheet flow curve and sizing before you order.
The L in the code marks the low-pressure regulator type, intended for circuits set below the standard type's range. The exact adjustment range for this variant is not published in the material we hold, so ask us to confirm it against your set pressure before ordering.
