The AirTAC GFR60020AJC3T 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 GFR60020AJC3T is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size-600 unit has a 3/4 in NPT thread, an automatic drain that expels collected condensate from the bowl without manual attention, a 40 um standard filter element, and a fitted round pressure gauge scaled in bar. The bowl on size-600 units is aluminium alloy. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, no reverse/check valve fitted, and no mounting bracket (code J).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W), gauge and thread options, and a low-pressure type in the catalogue. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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 the clamps, chucks and tool-change cylinders of a CNC machining cell, with the automatic drain coping with condensate carried in from a long plant-air drop.
Supplying the guide-rail adjusters, stop gates and diverters on a bottling or canning conveyor line, where one 3/4 in branch feeds several actuators at a held set pressure.
Conditioning the air supply to a small pneumatic stamping or forming press, protecting the valve stack downstream while the bar-scale gauge lets operators verify the set pressure at a glance.
Choose GFR when one body must both clean the air and hold a set pressure. Step through sizes 200/300/400/600 to match the port and duty; this unit is size 600 with a 3/4 in NPT thread. Drain: automatic here - the catalogue also offers manual and differential-pressure drains on the same size. Element: 40 um standard; specify code W for the 5 um grade where finer filtration is needed. The round gauge on this unit reads in bar; the embedded square gauge and MPa or psi scales are the other catalogue choices. Thread: PT is the AirTAC standard, with G (BSPP) and NPT as order options - this unit is ordered as NPT. Bracket is omitted with code J. Because flow is published only as curves, not a single rated number, ask us to confirm sizing against your application before ordering.
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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
Code A fits the automatic drain, which expels collected condensate from the bowl without anyone opening it - useful on lines that run unattended. The catalogue also offers manual and differential-pressure drains on this size if you prefer a different arrangement.
