The AirTAC GFR60020AJC3TK AirTAC Filter Regulator NPT3/4 with Gauge 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 GFR60020AJC3TK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 3/4 in NPT unit is set up with an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, an external round gauge reading in bar, and a built-in reverse (check) valve that holds the downstream setting if upstream supply is interrupted. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and this code specifies no mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of PT, G or NPT threads, manual, automatic or differential-pressure drains, a 5 um optional element, and gauge scale options. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures against your application on request.

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 3/4 in take-off feeding an assembly cell, it cleans the shop air, holds a steady regulated pressure to the cell's actuators, and its automatic drain keeps condensate out of the distribution leg without daily attention.
Mounted on the supply to a cartoning or wrapping machine, it protects the machine's valves and cylinders from water and debris, sets the working pressure the machine was designed for, and the check valve holds that setting through brief supply dips.
Fitted ahead of a machining centre's pneumatic circuit, it conditions the incoming compressed air, regulates the pressure feeding clamps and tool-change cylinders, and the bar gauge gives operators a visible reference at the machine.
Size 600 with a 3/4 in port sits at the top of the GFR range, so step up or down through 200/300/400/600 to match the pipe bore and the flow your line needs - the published flow curves, not a single rating, are the honest basis for that choice, and we will confirm them for your duty on request. The automatic drain on this unit suits unattended installations; choose manual drain where you want condensate removal under operator control, or the differential-pressure default where drain behaviour should follow the pressure drop. The 40 um element is the standard grade; specify the W code for the 5 um option if downstream equipment needs finer filtration. The round gauge here reads in bar, and MPa or psi scales can be ordered instead; PT is the standard thread with G and NPT as order options, and a bracket can be added where this no-bracket code does not include one.
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. Send us your application details and we will confirm the datasheet flow data for this 3/4 in unit against your requirement before you order.
The A in the code sets the automatic drain, which ejects collected condensate by itself instead of waiting for a manual blowdown, and the K sets a built-in reverse (check) valve that holds the regulated downstream pressure if the upstream supply drops. Both are decodable choices: manual or differential-pressure drains and a non-check version can be ordered instead.
