The AirTAC GFR600C20MF3WT 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 GFR600C20MF3WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one size-600 body with a 3/4 in NPT port. This configuration carries the W-code 5 um filter element (finer than the standard 40 um), a manual drain on the bowl, and an embedded square gauge reading in bar. Because it is the 600 size, the bowl is aluminium alloy rather than polycarbonate. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating 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 ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, square or external round gauges with MPa, psi or bar scales, G, NPT or PT threads, and optional brackets. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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.

Feeds filtered, regulated air to a machining centre's pneumatic clamps and tool-change cylinders, with the 5 um element protecting fine valve internals and the bar-scale gauge letting setters verify clamp pressure at a glance.
Sits at the drop of a packaging line's air main to remove water and pipe scale before diverters and pusher cylinders, holding a stable set pressure so carton forming and sealing strokes stay consistent through the shift.
Prepares air ahead of filler and capper valve manifolds in a bottling hall, draining accumulated condensate manually at shift checks and regulating supply to the pressure the valve island was specified for.
Size and port are the first decision: 600 is the largest GFR frame, and the port step (1/8 in up to 1 in across the family) should be matched to the air demand of the circuit downstream. This unit is threaded NPT3/4; PT is the catalogue standard and G (BSPP) is also available to order. Drain type is a real choice: manual drain means someone opens the bowl drain periodically, while automatic and differential-pressure drains discharge condensate without operator action - manual suits attended installations, automatic suits enclosed or hard-to-reach ones. Filter grade is 5 um here (code W) against the 40 um standard; choose 5 um where downstream valves and instruments need finer protection. The gauge is the embedded square type with a bar scale; MPa, psi scales and an external round gauge are alternatives. A mounting bracket is included with this unit. Because flow is published as curves and not a single rating, 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 number, so we do not quote a figure here. Tell us your application's air demand and we will confirm the flow from the datasheet curves for this exact model before you order.
The M in the code GFR600C20MF3WT specifies a manual drain: condensate collected in the aluminium alloy bowl is released by opening the drain by hand, which suits attended installations on a maintenance routine. The same GFR600 size is also available with an automatic or a differential-pressure drain if you want condensate discharged without operator action.
