The AirTAC GFR60020AC2K AirTAC Filter Regulator PT3/4, 40 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 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 GFR60020AC2K is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in PT port, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and an aluminium alloy bowl - the material used at size 600. The built-in regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a reverse/check valve is fitted. A round external gauge on a psi scale is included so the set pressure can be read directly.
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, and options including manual or differential-pressure drains, a 5 um element (code W), square embedded or round external gauges on MPa, psi or bar scales, and G or NPT threads in place of PT. 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.

Installed at the take-off point of a factory compressed-air ring main, it strips condensate and pipe-scale from the supply and holds a steady regulated pressure for the downstream drop to production cells.
Feeding cylinders and air-operated valves on a packaging or palletising conveyor, it keeps the actuator supply clean and at a fixed set pressure so cycle behaviour stays consistent through the shift.
Used in a maintenance bay or vehicle-build application, it conditions shop air before it reaches brake-testing rigs, tyre equipment and air-tool stations, with the automatic drain coping between uses.
Size 600 with a 3/4 in PT port is the largest step in the GFR range, so size the unit against the flow your line needs and step down to 400/300/200 if the demand is smaller. Drain choice matters: the automatic drain on this model suits unmanned or hard-to-reach installations, while manual and differential-pressure drains are available where a different regime fits better. The 40 um element is the standard grade; specify 5 um (code W) if finer particulate removal is required. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are alternatives, and G (BSPP) or NPT threads can be ordered instead of PT. A mounting bracket is included.
Because AirTAC publishes flow as curves rather than a single rating, we do not quote one number here. Send us your application details and we will confirm the 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 GFR600 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet for your exact conditions before you order.
The A in the code specifies an automatic drain: the bowl expels collected condensate on its own, which suits installations that are not checked daily. Manual and differential-pressure drain versions of the same GFR600 unit are available in the catalogue if you prefer to control drainage yourself.
