The AirTAC GFR60020ALF3T AirTAC Filter Regulator NPT3/4 Low-Pressure 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 GFR60020ALF3T is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit carries a 3/4 in NPT thread, a 40 um standard filtration element, and an automatic drain that expels collected condensate without manual attention. It is the low-pressure regulator type and comes with an embedded square gauge scaled in bar; a mounting bracket is included.
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), alternative gauge scales in MPa or psi, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 filtered, regulated air to a pneumatic press or forming station that runs at reduced line pressure, where the low-pressure regulator type and automatic drain keep the setup stable without daily bowl attention.
Conditioning the 3/4 in main drop feeding actuators and grippers on a packaging line, with the 40 um element protecting valves from water and debris and the bar gauge giving operators a local pressure readout.
A compact filter-regulator point on textile or process machinery where a separate filter and regulator would take extra panel space, with the included bracket mounting the unit at the machine inlet.
Size 600 with a 3/4 in port is the step to specify when line size and air demand point to the larger end of the GFR range; smaller sizes 200-400 step down in port and body size. Drain choice matters here: this unit has an automatic drain, which suits unattended installations, while manual and differential-pressure drains are the alternatives in the family. The 40 um element is the standard grade; the 5 um W grade is available where finer particulate capture is needed. The fitted square gauge reads in bar; MPa or psi scales and an external round gauge can be ordered instead. NPT is specified by this code; PT (standard) and G (BSPP) are the other catalogue thread options, and a mounting bracket is included.
Because flow is published as curves and not as a single rated figure, we do not quote a number here. Send us your application details 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this family as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The A in the code specifies an automatic drain, which discharges collected condensate from the bowl without operator intervention - useful for unattended or hard-to-reach installations. The GFR family is also available with a manual drain or the differential-pressure default drain, ordered via the drain code position.
