The AirTAC GFR600C20LJC3T AirTAC Filter Regulator NPT3/4 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 GFR600C20LJC3T is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This size 600 unit has a 3/4 in NPT port, the low-pressure regulator type, a 40 um standard filter element, a differential-pressure drain on the bowl, and a round pressure gauge reading in bar. No mounting bracket is fitted and no reverse/check valve is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The bowl on this largest size is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and options include automatic or manual drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and a mounting bracket. Flow is published as curves rather than a single rating, so ask us to 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.

Filtering and regulating the air feeding gripper and clamp cylinders on a beverage bottling line, where a low set pressure keeps bottle-handling actuation gentle and the drain clears condensed water from the supply.
Conditioning the branch feed to a laboratory's pneumatic bench valves and sample-handling cylinders, with the 40 um element catching pipe scale and the regulator holding a steady low branch pressure.
Supplying air to diverter and stopper cylinders on a carton conveyor, where the low-pressure regulator holds a steady setting so divert timing stays repeatable shift after shift.
Choose the size by the port and flow step: sizes 200, 300, 400 and 600 step up from 1/8 to 1 in ports, and larger sizes carry more flow - confirm the curve against your demand before ordering. This unit is the low-pressure regulator type, so confirm its adjustment range with us if your set point is outside the ordinary. Drain choices are differential-pressure (this unit), automatic (code A) or manual (code M). Filter grade is 40 um standard or 5 um with code W. Gauge options are the embedded square gauge or an external round gauge in MPa, psi or bar scales - this unit carries a round gauge reading bar. Thread is NPT here; PT is the standard and G (BSPP) is also available. Brackets are optional - this configuration has none.
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 GFR600 series as curves, not a single rated number, so we do not quote a figure here. Send us your line pressure, set pressure and air demand and we will confirm the datasheet curve and sizing for your application.
The L in GFR600C20LJC3T marks the low-pressure regulator type, intended for lower set pressures than the standard version. Its exact adjustment range is not published in the catalogue sheet, so ask us to confirm it against your set point before ordering.
