The AirTAC GFR60020MLC2W 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 GFR60020MLC2W is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 5 um filter element (code W), a manual drain on the bowl, a low-pressure regulator type, and an external round gauge with a psi scale. The port is PT3/4 (3/4 in, PT thread as standard, with G and NPT available as order options). At size 600 the bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options across filter grade (40 um standard, 5 um), drain type (manual, automatic, or differential-pressure), gauge style and scale, low-pressure type, reverse/check valve, and bracket. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet figures on request before you order.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Drops feeding a hall of case packers and wrappers get one unit that strips water and chips and holds a steady reduced pressure at the 3/4 in main, with the psi gauge read at a glance during shift checks.
Air cylinders that index and gate product on a conveyor line need clean, dry air at a fixed setting; this filter regulator conditions the branch feed and the manual drain is emptied during scheduled line stops.
On an OEM control panel, the 3/4 in supply passes through this unit before distribution to valves and actuators, with the low-pressure regulator set where the circuit needs a reduced supply below the standard range.
Start with the size and port: size 600 with a PT3/4 port is the largest step in the GFR range, so match it against the air demand of the line it feeds. Choose the drain to suit access: manual drain (this unit) needs someone to open it, while automatic and differential-pressure drains handle it for you. The 5 um element (this unit) suits finer protection than the 40 um standard grade. Gauge options are an embedded square gauge or an external round gauge, with MPa, psi or bar scales - this unit has a round psi gauge. Thread is PT as standard; G (BSPP) and NPT are order options. A bracket is included with this unit. One honest note: flow is published as curves, not a single rating, so ask us to confirm sizing against your 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 there is no one rated flow number we can quote. Send us your line pressure, downstream setting and air demand, and we will confirm the sizing from the datasheet on request before you order.
The M in the code sets a manual drain: condensate collects in the aluminium alloy bowl and is released by hand, which suits installations on a scheduled maintenance round. The W sets the 5 um filter element instead of the 40 um standard grade, for finer particulate removal ahead of sensitive downstream equipment.
