The AirTAC GFR600C20MLJF2T 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 GFR600C20MLJF2T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has a 3/4 in NPT port, a manual drain on the bowl, the standard 40 um filter element, and the low-pressure regulator type. It ships as configured with the embedded square gauge scaled in psi, an aluminium alloy bowl, and no mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain type, 40 um or 5 um filtration, gauge scale options, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application on request.

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 supplied to clamp cylinders on a CNC fixture line, where the low-pressure regulator type holds the clamping circuit at a reduced, stable setting.
Conditioning the air feed to spray guns in a finishing booth: the 40 um element strips water and particulate that would otherwise spoil the finish, while the regulator sets gun supply pressure.
Supplying clean, regulated air to the cylinders and air jets on a packaging line, with the manual drain bled during scheduled changeover stops.
Size and port set the air capacity: this unit is size 600 with a 3/4 in NPT port, the largest step in the range - step up or down (200/300/400/600) to match the line. Drain is a real choice: manual (this unit, code M) needs periodic bleeding, while automatic and differential-pressure drain types discharge condensate without attention. Filtration is 40 um standard; specify code W for the 5 um element where downstream equipment needs finer protection. The square gauge is fitted here with a psi scale (MPa and bar scales are alternatives), and the low-pressure regulator type suits circuits held below standard supply pressure - confirm its exact range with us before ordering. Thread is NPT here; PT (standard) and G are order options. A bracket is optional (not fitted on this code).
Because flow for this series is published as curves and not as 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a flow number. Send us your line pressure and air demand and we will confirm the datasheet flow curve for this size 600, 3/4 in unit on request.
Code M specifies a manual drain: condensate collects in the aluminium alloy bowl and is bled by hand, which suits attended lines or scheduled maintenance routines. The GFR family also offers automatic and differential-pressure drain types that discharge condensate without operator action - ask us to quote the equivalent code if you prefer one of those.
