The AirTAC GFR600C20MLJC3WT 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 AirTAC GFR600C20MLJC3WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built with a 3/4 in NPT port, a fine 5 um filter element (the 40 um standard element is the alternative), a manual drain on the bowl, the low-pressure regulator type, and a round pressure gauge reading in bar. The bowl on this size is aluminium alloy, and the unit is supplied without a mounting bracket and without a reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G and NPT thread options. Because AirTAC publishes flow for this series as curves rather than a single rating, we confirm the datasheet and flow figures for your application on request - just ask 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.

Feeding a workshop air press or clamping fixture: the 5 um element keeps water and swarf out of the valve stack, the low-pressure regulator holds a gentle setting for clamping force, and the bar gauge gives the operator a clear reading at the machine.
Supplying cylinders and grippers on a cartoning or wrapping line: filtered, regulated air at a stable low setting protects the actuators, the manual drain lets maintenance empty the aluminium bowl during scheduled changeovers, and the 3/4 in NPT port suits the machine's main drop.
Conditioning supply air for a test rig or laboratory bench: the fine 5 um grade suits sensitive instruments and gauges, the low-pressure regulator type covers applications that run well below standard line pressure, and the round bar gauge allows direct verification of the test setting.
Step through the real choices before ordering. Size 600 with a 3/4 in port is the largest step in the GFR range; match size and port to the flow your line needs rather than to pipe diameter alone, and note that flow is published as curves, not a single rating, so ask us to confirm sizing against your application. Drain type is a genuine decision: this unit has a manual drain, which means an operator drains the bowl; automatic and differential-pressure drains are available on other codes in the family if you want unattended drainage. The filter grade here is the fine 5 um element (code W); the 40 um standard element suits general supply lines, while 5 um suits components that need cleaner air. The gauge on this code is the round external type reading in bar; embedded square gauges and MPa or psi scales are the other options. Thread is NPT on this code, with PT (standard) and G also orderable. A mounting bracket can be added on bracket-included variants; this code omits it. The regulator is the low-pressure type - its exact adjustment range is not published in our data, so confirm it with us on request.
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 rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
This code carries a manual drain: an operator opens it to empty collected water from the aluminium alloy bowl, which suits lines that are checked regularly. The GFR family also offers automatic and differential-pressure drains on other codes for unattended drainage - ask us for the matching model if you prefer that.
