The AirTAC GFR600C20MLC2WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20MLC2WTK is a 600-size filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built for 3/4 in NPT ports, carries the fine 5 um (W) filter element, and uses a manual drain, so condensate is released by opening the drain fitting by hand. It is the low-pressure regulator type, and the code specifies a round pressure gauge scaled in psi, a reverse/check valve, and an included mounting bracket. At size 600 the bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um fine filtration, gauge styles and scales, PT, G or NPT threads, and optional check valves. Flow is published as curves rather than a single rating, so ask us to confirm flow and datasheet figures for 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.

On a stamping or assembly press fed from a plant air main, this 3/4 in filter regulator cleans the supply to 5 um and holds the working pressure the press cylinder was set up for, with the check valve holding the circuit if the main drops.
In a paint or powder-coating booth line, the 5 um element keeps water and particles out of the atomizing air, and the low-pressure regulator type is the right choice where the gun circuit runs at modest setpoints rather than full line pressure.
For the cylinder and valve bank circuit on a carton-sealing or palletizing conveyor, this unit conditions the 3/4 in branch feed and regulates it to the pressure the actuators were sized for, with the psi gauge giving operators a visible setpoint.
Start with the port and size: this unit steps up to 3/4 in NPT in the 600 frame, the largest in the GFR range, so match it against the pipe size and air demand of the circuit it feeds. Because it is the low-pressure (L) regulator type, it suits circuits held below the standard regulator's range - confirm the exact setpoint you need with us before ordering. The manual drain means someone opens the drain fitting periodically; if the unit will sit unattended, ask about the automatic or differential-pressure drain versions instead. The 5 um (W) element protects sensitive downstream components; the standard grade is 40 um. The round gauge here is scaled in psi, with MPa and bar scales available, and PT is the standard thread with G and NPT as order options. A mounting bracket is included.
Flow for this family is published as curves, not a single rated figure, 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 one. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the flow figures from the datasheet for this exact model before you order.
The M in the code specifies a manual drain: condensate collected in the aluminium bowl is released by opening the drain fitting by hand. That suits lines that are checked on a routine schedule. If the unit will run unattended for long shifts, ask us about the automatic (A) or differential-pressure (blank) drain versions of the same GFR600 configuration.
