The AirTAC GFR600C20MJF2WTK AirTAC Filter Regulator NPT3/4, 5 um 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 GFR600C20MJF2WTK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in NPT port, a 5 um filter element (the finer of the two available grades), a manual drain on the metal bowl, an embedded square gauge with a psi scale, and a built-in reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi); the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of port sizes, PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge scale options and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet figures 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.

Installed at the 3/4 in main drop feeding a CNC machining cell, it filters water and chips-laden particulate from the header air and holds a set regulator pressure for the cell's actuators and air tools, with the psi gauge giving operators a local reading.
Mounted ahead of the valve manifold on a cartoning or case-packing conveyor line, it delivers cleaned, regulated air to cylinders and grippers, while the reverse/check valve holds the downstream setting if the supply side dips.
Fitted at the supply point of a fleet maintenance bay, it conditions shop compressor air before it reaches impact wrenches and inflation stations, with the 5 um element limiting fine contamination and the manual drain cleared at the end of each shift.
Choose the size and port step against the air demand of the circuit: this unit is the 600 size with a 3/4 in NPT port, the largest step in the family. Because published flow data is presented as curves and not a single rating, ask us to confirm sizing against your application before ordering. On this configuration the drain is manual, so plan a routine blow-down interval; automatic and differential-pressure drains are available on other variants if you prefer unattended drainage. The 5 um element (code W) suits points of use that need finer particulate control than the standard 40 um grade; note that a finer element loads faster and needs more frequent checking with a manual drain.
The square gauge here reads in psi; MPa and bar scales are alternatives on other variants, and an external round gauge is optional. The T in the code fixes the thread as NPT; PT is the standard thread and G (BSPP) is also a catalogue option. This unit is ordered without a mounting bracket (code J); brackets are available on other variants.
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 family as curves, not as a single rated number, so we do not quote a l/min, m3/h or SCFM figure. Tell us your application and we will confirm the flow and datasheet figures for this 3/4 in, size-600 unit on request before you order.
The M in the code specifies a manual drain: condensate collects in the metal bowl until someone opens the drain. It is the right choice where the unit is checked on a routine schedule; if you need unattended drainage, the differential-pressure (default) or automatic drain variants of the same GFR600 filter regulator are the alternatives to ask for.
