The AirTAC GFR60020F3WT AirTAC Filter Regulator 3/4 in NPT, 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 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 GFR60020F3WT is a size-600 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration has a 3/4 in NPT port, a fine 5 um filter element (W grade), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an embedded square gauge reading in bar. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range, and maximum inlet pressure is 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, and operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um fine filtration, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet 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.

Clean, regulated air for the clutch and cylinder circuit of a mechanical stamping press, with the 5 um element protecting the press valve stack from rust particles and pipe scale.
A single 3/4 in supply point feeding the air cylinders and diverters on a carton sorting conveyor, holding a stable set pressure as the line cycles through shifts.
Regulated, filtered air at a heavy-vehicle workshop drop, supplying impact wrenches and lifting bags while the fine element keeps moisture and debris out of the tools.
Size 600 with a 3/4 in port is the largest step in the GFR range, so start there when your line's air demand is high; smaller sizes 200/300/400 step down in port and capacity. Because flow is published as curves and not a single rated figure, send us your required flow and we will confirm sizing against the datasheet before you order. This unit carries the 5 um (W) element - choose it over the 40 um standard grade when downstream valves, cylinders or instruments need finer protection. The differential-pressure drain suits installations with steady, continuous flow; pick the automatic drain code for intermittent flow or unattended duty, and the manual drain code where an operator can bleed the bowl on a routine. The square gauge here reads in bar; psi and MPa scales are available, and an external round gauge is an option. The T in the code gives NPT threads; PT is the catalogue standard and G (BSPP) can be ordered. A mounting bracket is included with this configuration.
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 GFR600 as curves rather than a single rated figure, so we do not quote one number. Tell us your required flow and working pressure and we will confirm the datasheet figure for this exact 3/4 in NPT, 5 um configuration before you order.
The W in the code selects the 5 um fine filtration grade instead of the 40 um standard. Choose 5 um where downstream valves, cylinders or instruments need finer protection from particulate; the 40 um grade remains available in the same GFR600 series if coarse filtration is sufficient.
