The AirTAC GFR600C20MC3T AirTAC Filter Regulator NPT3/4, 40 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 GFR600C20MC3T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/4 in NPT port, the standard 40 um filter element, and a manual drain bowl, so condensate is released when an operator opens the drain rather than automatically. The manual-drain version regulates from 0.05 to 0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). A round pressure gauge with a bar scale is fitted, and the operating temperature range 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 port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W), and G or NPT thread options. Flow is published as curves rather than a single rated figure, 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.

Installed at the take-off point of a factory compressed-air ring main, it cleans water and scale from the supply and lets each zone set its own working pressure at the 3/4 in branch line.
Mounted on a control panel air supply, it conditions the air feeding downstream valves and cylinders and holds the panel pressure steady, with the bar-scale gauge giving operators a local reading.
Placed ahead of the air cylinders and actuators that drive a conveyor or packaging line, it removes condensate carried in the header and lets maintenance set the pressure the mechanism was designed for.
Size 600 with a 3/4 in port is the largest step in the GFR range; step up or down through 200/300/400/600 to match the pipe size and flow demand of the line. This unit has the standard 40 um element, which suits general plant air; choose the 5 um (W) option where finer particulate removal is needed. The manual drain suits positions where an operator can bleed the bowl routinely; automatic or differential-pressure drain variants suit unattended installations. The fitted round gauge reads in bar; embedded square gauges and MPa or psi scales are available. Thread here is NPT; PT is the standard and G (BSPP) is an order option. A mounting bracket is included.
Flow for this family is published as curves, not a single rating, so 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 number, so we do not quote a figure here. Send us your line pressure and demand and we will confirm the flow data from the datasheet for this exact model on request.
The M in the code specifies a manual drain bowl: condensate collects until an operator opens the drain. It suits installations that are checked routinely. If the unit will sit unattended, ask about the automatic or differential-pressure drain variants of the same GFR600 size.
