The AirTAC GFR60020AF2WT AirTAC Filter Regulator NPT3/4 5um 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 GFR60020AF2WT is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate down to 5 um (the fine W grade, instead of the standard 40 um) and regulates downstream pressure across the standard 0.15-0.9 MPa (20-130 psi) range. This size-600 unit is configured with 3/4in NPT ports, an automatic drain that ejects collected condensate without manual attention, an embedded square gauge scaled in psi, and no reverse/check valve. The bowl on this size is aluminium alloy, and max inlet pressure is 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8in to 1in, and options for manual or automatic or differential-pressure drains, 40 um or 5 um filtration, gauge scale, thread (PT standard, G and NPT to order) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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 0.15 - 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.

Fine 5 um filtration plus regulated pressure on the air drop feeding paint guns and air-assisted applicators, with the automatic drain coping with condensate on a continuously running supply line.
Conditioning the 3/4in main feeding pneumatic cylinders and grippers on a bottling or cartoning conveyor, where the automatic drain keeps water out of the valve manifold without daily bowl checks.
Supplying clean, regulated air to quarter-turn pneumatic actuators and positioners on a water-treatment or chemical skid, with the psi-scaled gauge giving operators a local setpoint readout.
Size and port set the capacity ceiling: the 600 frame with 3/4in NPT ports suits the larger end of the GFR range, but because flow is published as curves and not a single rating, match the curve to your demand before ordering - we will confirm sizing on request. Drain type is a real choice here: this unit has an automatic drain (code A), which suits unattended or hard-to-reach installations; manual and differential-pressure drains are available on other variants. Filtration is the 5 um W grade - choose it where downstream valves and instruments need finer air than the 40 um standard. The gauge is the embedded square type scaled in psi (MPa and bar scales exist), and the thread here is NPT; PT is the catalogue standard with G and NPT as order options, and a 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 GFR flow as curves, not as a single rated number, so we do not quote a figure here. Send us your application details and we will confirm the flow and datasheet figures for this 3/4in size-600 unit on request before you order.
The A in the code means an automatic drain: collected condensate is ejected on its own, which suits unattended or hard-to-access installations where a manual or differential-pressure drain might be neglected. The W grade filters to 5 um instead of the 40 um standard, giving finer protection for downstream valves, cylinders and instruments.
