The AirTAC GFR600C20MLJC3TK AirTAC Filter Regulator NPT3/4 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 GFR600C20MLJC3TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration decodes with a 3/4 in NPT port, a manual-drain metal bowl (aluminium alloy at size 600), the standard 40 um filter element, the low-pressure regulator type, an external round gauge with bar scale, and a built-in check valve; it is supplied without a mounting bracket.
It is a genuine AirTAC part from the GFR family, which spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, PT/G/NPT threads, automatic, manual or differential-pressure drains, 40 um or 5 um elements, and a choice of embedded square or external round gauges. 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 rated figure, so ask us to confirm 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.

Filtered, regulated air at reduced pressure feeding the capping cylinders on a bottling line; the manual-drain aluminium bowl suits a line that already runs scheduled maintenance rounds.
Supplying diverters and stopper gates along a packaging conveyor, where one body filters the air and holds the reduced pressure the gate cylinders were set up for, with a bar-scale gauge for local setting.
Conditioning the supply to bench valves and small actuators on a laboratory or test-house air ring main, with the built-in check valve preventing backflow into the conditioned branch.
The real choices on a GFR unit are size and port, drain type, filter grade, gauge and thread. Size 600 with a 3/4 in NPT port is the largest step in the range; match it to your pipe size and the flow your line needs. The manual drain means an operator opens the bowl drain during service rounds instead of relying on an automatic or differential-pressure drain. The 40 um element is the standard grade; a 5 um element (code W) is available where finer filtration is required. The round gauge fitted here reads in bar; embedded square gauges and MPa or psi scales are the alternatives. G and NPT threads are order options alongside the PT standard, and a mounting bracket can be added if this no-bracket configuration needs one. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against 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 GFR flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and port size, and we will confirm the sizing from the datasheet on request.
This unit is the low-pressure regulator variant, so its adjustment range differs from the standard type and the exact range is not published in the catalogue; ask us to confirm it for your application before ordering. Everything else decodes normally: manual drain, 40 um element, round bar-scale gauge, check valve fitted, and no mounting bracket.
