The AirTAC GFR600C20LJNT AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20LJNT is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at a set point. This size 600 unit is built for 3/4 in NPT ports, is the low-pressure type, carries the standard 40 um filter element, and drains condensate by differential pressure. No pressure gauge is fitted and no mounting bracket is supplied, and the 600-size bowl is aluminium alloy. Working temperature is -5 to 70 C (non-freezing) with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, filter grades of 40 um standard or 5 um (code W), drain choices of differential-pressure, automatic or manual, gauge and thread options, and standard or low-pressure regulation. Flow is published as curves rather than a single rating, so ask us to confirm 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.

Conditioning the air that feeds the cylinder banks driving filler and capper motions on a beverage bottling line, with the 3/4 in NPT port matching a main drop leg.
Supplying filtered, regulated low-pressure air to pneumatic clamp cylinders on a panel-gluing press, with the 40 um element keeping chips and water out of the valve stack.
Preparing the air that drives diverters and pushers along a carton conveyor, holding a steady set point so actuators repeat their stroke without pressure drift.
Size and port set the flow path: this unit steps up to the size 600 frame with 3/4 in NPT threads, the right choice when the air demand on your line calls for the larger GFR body. Drain type is a real decision: differential-pressure (this unit) vents condensate when the pressure drop across the element rises, while automatic (code A) and manual (code M) variants are orderable. Filter grade is 40 um standard here; specify code W for 5 um where finer particulate matters. A gauge (embedded square or external round, with MPa, psi or bar scales), PT or G threads, and bracket inclusion are all orderable options. Flow is published as curves, not a single rating, so 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line's air demand and we will confirm the sizing from the datasheet on request before you order.
N means no pressure gauge is fitted and J means no mounting bracket is supplied; both are orderable options if you want them. The unit is the low-pressure type with a 40 um element and a differential-pressure drain, threaded 3/4 in NPT (PT is the standard thread; G and NPT are order options).
