The AirTAC GFR60020AC1WTK AirTAC Filter Regulator NPT3/4 5um Auto Drain 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 GFR60020AC1WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a 5 um filter element (the finer of the two grades), an automatic drain that ejects collected condensate without manual attention, a round pressure gauge with an MPa scale, and a reverse/check valve. The 3/4 in NPT port suits higher-flow supply lines, and the aluminium alloy bowl is the material used at this size. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 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 port sizes from 1/8 in to 1 in, a choice of drain types, 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm flow and other 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. 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.

Feeding spray-booth and paint-pump air drops on a finishing line, where the 5 um element helps keep water and particles out of the air supply ahead of the spray equipment and the regulator holds a steady set pressure for the guns.
Mounted at the inlet of a machine's pneumatic manifold, conditioning and regulating the plant air that feeds valves and actuators, with the automatic drain handling condensate and the check valve holding the circuit if supply pressure dips.
Conditioning the air feeding carton sealers, case packers and conveyor diverters, where the regulator keeps cylinder speeds consistent and the 3/4 in port matches the main drop feeding several machines.
Size 600 with a 3/4 in port is the step to choose when the supply line and required air volume point to the larger end of the GFR range; smaller sizes (200/300/400) step down in port and flow capacity. This unit already carries the 5 um element (code W) instead of the 40 um standard, the automatic drain instead of manual or differential-pressure drain, a round MPa gauge, and a reverse/check valve. Thread is NPT; PT and G (BSPP) are catalogue alternatives if your piping standard differs. A mounting bracket is included.
Because AirTAC publishes flow as curves rather than a single rated number, we do not quote a rated flow figure here. Send us your line size, working pressure and air demand, and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a rated flow number for this unit. Send us your line size, inlet pressure and air demand, and we will confirm the flow and the full datasheet figures on request before you order.
The A in the code selects the automatic drain, which ejects collected condensate from the aluminium alloy bowl without anyone opening it - useful on lines that run unattended. The W selects the 5 um filter element instead of the 40 um standard, giving finer particulate removal. Both are order-time choices across the GFR range, along with drain type, gauge style and scale, and PT, G or NPT threads.
