The AirTAC GFR600C20MJC2WK AirTAC Filter Regulator 3/4in PT 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 GFR600C20MJC2WK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 5 um filtration element (the finer grade, in place of the 40 um standard), a manual drain bowl, a fitted reverse/check valve, and an external round pressure gauge scaled in psi. The port is PT3/4 (3/4 inch PT thread, the standard for this model, with G and NPT threads available as order options). With a manual drain, condensed water is released by opening the drain valve by hand, so the bowl should be checked as part of a routine maintenance walk. The aluminium alloy bowl on this size 600 unit suits demanding industrial environments, and the standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 inch to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge and scale options, and an optional reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and check sizing against 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.

Installed at the take-off from a factory compressed-air ring main, the 3/4 inch size 600 body conditions the supply feeding a production bay: the 5 um element strips water and fine particulate before the regulator sets a stable working pressure for the whole bay.
Mounted ahead of the cylinder and actuator bank on a packaging or palletising conveyor line, this unit filters the shop air to 5 um and holds the regulated pressure the cylinders were sized for, with the psi gauge giving operators a visible setpoint and the check valve holding pressure through brief supply dips.
Built into an OEM machine's pneumatic panel as the single conditioning point for the machine's valve and cylinder circuit, the filter-regulator combination keeps the FRL footprint small while the manual drain slots into the builder's scheduled maintenance routine.
For this model the key decodable choices are already fixed: size 600 with a PT3/4 port for higher-flow lines, the 5 um element where downstream equipment needs finer filtration than the 40 um standard, a manual drain where a maintenance schedule exists (choose automatic or differential-pressure drain if you cannot guarantee regular manual blowdowns), a round psi gauge, and a fitted reverse/check valve to hold downstream pressure if upstream supply drops. The no-bracket configuration means you must provide your own mounting arrangement. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order if your piping requires them.
When stepping between sizes 200, 300, 400 and 600, match the port and body size to the flow your line needs - but note that flow for this series is published as curves, not a single rating, so ask us to confirm the datasheet and check sizing against the 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a rated flow number. Ask us and we will confirm the datasheet curves for the GFR600 and check the sizing against your application before you order.
The M in the code selects the manual drain: condensed water collects in the bowl and is released by opening the drain valve by hand, so the bowl needs to be checked on a routine maintenance schedule. If that is not practical at your site, the GFR600 is also available with automatic or differential-pressure drains - ask us for those variants.
