The AirTAC GFR60020AC3WT AirTAC Filter Regulator NPT3/4 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 automatic 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 GFR60020AC3WT is a 600-size filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 3/4 in NPT port, a 5 um filter element (the fine grade; 40 um is the standard option), an automatic drain that expels collected condensate without manual attention, and an external round gauge reading in bar. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, and the unit operates from -5 to 70 C in non-freezing conditions.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of PT (standard), G or NPT thread, manual, automatic or differential-pressure drains, 40 um or 5 um filtration, gauge style and scale options, and an optional reverse/check valve. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

Point-of-use conditioning ahead of spray booths and paint guns, where the 5 um element and regulated pressure help deliver clean, steady air to finishing equipment on a 3/4 in supply line.
Feeding cylinders and grippers on a bottling or carton-packing conveyor, with the automatic drain handling condensate on a line that runs unattended through long shifts.
Conditioning the shop-air feed to a CNC machining centre's pneumatic tool-changer and clamping circuits, where the round bar gauge lets operators verify set pressure at the machine.
Start with the port and size step: the 600 frame with its 3/4 in NPT port sits at the top of the GFR range, so match it against the air demand of the circuit - and because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. Choose the drain to suit access: this unit has an automatic drain, which suits installations that are not checked daily; manual and differential-pressure drains are available on other configurations. The 5 um element here is the finer grade - choose it where downstream equipment is sensitive to finer particles; 40 um is the standard grade for general supply. Gauge choices are the embedded square gauge (standard) or an external round gauge in MPa, psi or bar scales - this unit carries a round bar gauge. Thread is PT as the catalogue standard with G and NPT as order options; a mounting bracket is included.
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 series as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow and sizing from the datasheet on request before you order.
The A in the code GFR60020AC3WT means an automatic drain, which expels collected condensate from the aluminium alloy bowl on its own - useful for units mounted in awkward or infrequently visited spots. Manual and differential-pressure drain versions are available on other configurations if you prefer drain control at the bowl.
