The AirTAC GFR60020AJF2GK AirTAC Filter Regulator G3/4 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body, so one G3/4 connection handles both jobs on a compressed-air line. This configuration, GFR60020AJF2GK, is the size-600 unit with a G (BSPP) thread, an automatic drain that bleeds collected condensate without manual attention, a 40 um standard filter element, an embedded square gauge scaled in psi, and a reverse/check valve fitted to hold downstream pressure when the supply drops. The maximum working pressure is 1.0 MPa (145 psi), the standard regulation range with automatic drain is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
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 include a 5 um element (code W), manual or differential-pressure drain, an external round gauge with MPa, psi or bar scales, and PT or NPT threads. 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.

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.

| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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.

Dropping a filtered, regulated 3/4-in takeoff from a plant ring main to feed a packaging hall: the automatic drain keeps condensate off the regulators downstream while the psi gauge gives operators a local setpoint readout.
Feeding clamp cylinders and pallet-actuation cylinders on a machining centre, where the 40 um element stops swarf-carrying moisture reaching the valves and the check valve holds clamp pressure through a supply dip.
Supplying the air cylinders that drive diverters, gates and pushers on a distribution conveyor line, with the regulator set once at the panel and the automatic drain handling moisture from a long supply run.
Start with the size and port: the 600 step is the largest in the GFR range, and this unit carries a G3/4 connection - match it against the flow your line actually needs, since flow is published as curves rather than one rating and we will confirm sizing on request before you order. Because the drain is automatic, condensate is expelled without operator input; if your circuit cannot accommodate that, the same series is available with manual or differential-pressure drain. The 40 um element is the standard grade; choose the 5 um W option where downstream equipment needs finer filtration. The fitted square gauge reads in psi, and an external round gauge with MPa, psi or bar scales can be ordered instead. Thread here is G (BSPP); PT is the standard thread for the series and NPT is also an order option. Note this configuration comes without a mounting bracket.
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 application and we will confirm the datasheet flow figures on request so you can size the unit correctly before ordering.
This configuration carries code A, an automatic drain that expels collected condensate from the aluminium alloy bowl without manual attention, and with automatic drain the regulation range is 0.15-0.9 MPa (20-130 psi). If your installation suits it better, the same GFR600 size is available with manual drain (range 0.05-0.9 MPa) or the differential-pressure drain as the default option.
