The AirTAC GFR600C20AJF2 AirTAC Filter Regulator PT3/4 Auto Drain 40um 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 See datasheet ports, a differential-pressure 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 GFR600C20AJF2 is a size 600 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is fitted with a 3/4 in PT port, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and an embedded square gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). At size 600 the drain bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, optional 5 um elements (code W), manual or differential-pressure drains, alternative gauge scales, G or NPT threads, and bracket options. 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 a 3/4 in branch take-off from a factory compressed-air ring main, it cleans water and scale from the supply and holds a set pressure for the machines fed from that drop, with the automatic drain handling condensate between shifts.
Feeding the air cylinders and actuators on a cartoning or palletising conveyor, it removes moisture and particles before they reach seals and valves, and the psi gauge lets line staff set and check the regulator setting at a glance.
Mounted ahead of a control panel's solenoid valves and air-operated instruments, it filters the incoming air and regulates it to the pressure the panel components were specified for, with the square gauge giving a local pressure readout.
Size 600 with a 3/4 in PT port sits at the top of the GFR range, so step up or down through 200/300/400/600 against the flow your line actually needs - and confirm that against the published curves before ordering. This unit carries the 40 um standard element; choose the W code if the application needs 5 um. The automatic drain here suits unattended duty; manual and differential-pressure drains are the other catalogue choices. The square gauge is fitted in a psi scale (MPa and bar scales are alternatives), and G or NPT thread versions can be ordered instead of PT. This code is supplied without a mounting bracket; bracketed versions exist. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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 the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the relevant flow figures from the datasheet on request.
The A in the code specifies an automatic drain, which expels collected condensate from the bowl without anyone opening it - useful on unattended or hard-to-reach installations. The catalogue also offers manual and differential-pressure drains on the GFR family if you prefer a different arrangement.
