The AirTAC GFR60020MC2WK AirTAC Filter Regulator PT3/4, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020MC2WK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in one body. This configuration has PT3/4 ports, a 5 um filter element (code W), a manual-drain bowl in aluminium alloy, a round pressure gauge reading in psi, a built-in reverse (check) valve, and a mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series spans sizes 200 to 600 with ports from 1/8 to 1 in, a choice of drain type, 40 um standard or 5 um filtration, gauge style and scale, and G or NPT thread options to order. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application.

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 0.05 - 0.9 MPa (7 - 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.

Feeding spray guns on a finishing line: the 5 um element strips water and fine particulate that would ruin paint finish, while the regulator holds a steady gun pressure and the check valve keeps downstream pressure from backing up.
Supplying the pneumatic cylinders on a carton-sealing conveyor: clean, regulated air at the manifold keeps stroke timing consistent through the shift, and the PT3/4 port suits a main drop feeding multiple stations.
Running pneumatically actuated butterfly and diaphragm valves at a treatment plant: the regulator holds the actuator pressure the positioner expects, the 5 um grade protects small control-air passages, and the manual drain suits a attended plant room.
The real choices on this series: step size and port to match the flow your line needs (size 600 is the largest, here PT3/4); drain type - differential-pressure as standard, automatic, or manual (this unit is manual, so condensate is drained by opening the drain at the bowl bottom); filter grade 40 um standard or 5 um with W (this unit is 5 um for finer particulate); gauge style and scale; PT, G or NPT thread; and bracket. One honest note on sizing: flow is published as curves, not a single rated number, so send us your application and we will confirm the right size against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and full datasheet figures on request before you order.
The M in the code means a manual drain: condensate collected in the aluminium bowl is emptied by opening the drain fitting, which suits installations that are checked regularly. Other GFR variants come with automatic or differential-pressure drains, and the manual-drain version regulates from 0.05 to 0.9 MPa (7-130 psi).
