The AirTAC GFR600C20MC2WTK 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 GFR600C20MC2WTK is a size 600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration carries a 3/4 in NPT port, a 5 um filter element (finer than the 40 um standard), a manual drain on the bowl, an external round pressure gauge reading in psi, and a built-in reverse/check valve. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, and the unit is rated for -5 to 70 C (non-freezing) with a mounting bracket included.
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, and options including 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges with MPa, psi or bar scales, and G, NPT or PT threads. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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.

Point-of-use air preparation at assembly stations: the 5 um element strips water and fine particulate before air reaches torque tools and clamps, while the regulator holds a steady working pressure on a 3/4 in drop.
Supplying spray equipment in a wood-finishing booth, where the finer 5 um grade and stable regulated pressure help keep finish quality consistent, and the manual drain lets operators bleed accumulated condensate at shift end.
Feeding the cylinders and air gates along a bottling conveyor, with the check valve holding downstream pressure if upstream supply dips and the psi gauge giving operators a visible line-pressure reference.
Size 600 with a 3/4 in port is the largest step in the GFR range, so start by matching the port and body size to the air demand of the circuit; if your requirement sits below the capacity of this frame, the 400, 300 or 200 sizes with smaller ports may be the more economical choice. Drain type is a real decision: manual drain (as fitted here) needs an operator to bleed the bowl, while automatic and differential-pressure drains discharge condensate without attention. The 5 um element in this unit is the optional finer grade; the 40 um standard element suits general-purpose supply lines. The round psi gauge here is the optional external type - an embedded square gauge with MPa, psi or bar scales is also available. Thread comes as PT as standard, with G (BSPP) and NPT as order options, and the mounting bracket is included. Because flow for this series 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 flow for the GFR series as performance curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your line pressure and air demand and we will confirm the flow data from the datasheet for this exact model on request.
This configuration carries the M drain code, meaning condensate collected in the aluminium alloy bowl is released by hand - straightforward and reliable where an operator is already on site. If you cannot rely on manual bleeding, the same GFR600 body can be ordered with an automatic drain or the default differential-pressure drain; the manual-drain version also widens the regulator adjustment range to 0.05-0.9 MPa (7-130 psi).
