The AirTAC GFR60020AJF3TK 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 GFR60020AJF3TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This size 600 unit carries a 3/4 in NPT thread, an automatic drain that ejects collected condensate without manual attention, a standard 40 um filter element, and an embedded square gauge reading in bar. The fitted reverse (check) valve holds downstream settings, and the aluminium alloy bowl suits demanding installations. 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).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), a 5 um element option, gauge scale options and G/NPT thread variants. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.

| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 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.

Conditioning the shop-air feed to a CNC machine's pneumatic valves and clamps: the 40 um element stops scale and pipe debris, the regulator holds a steady setting for repeatable clamping, and the automatic drain keeps condensate out of the circuit on a 3/4 in main.
A filtered, regulated drop feeding carton-formers, sealers and pick-and-place cylinders on a packaging line. The check valve preserves the set pressure against upstream dips, and the automatic drain suits a line that runs long shifts unattended.
Mounting at the inlet of an assembly-cell control panel where air cylinders and air tools share one supply. The bar-scale gauge gives operators a local setpoint readout, and the aluminium alloy bowl and 3/4 in port support a high-demand manifold.
Size 600 with a 3/4 in port is the large-flow step of the GFR range; step up or down through sizes 200/300/400/600 as your line's air demand requires, and confirm the match against the published flow curves before ordering. This unit ships as configured with an automatic drain (no manual draining rounds), a 40 um element (a 5 um W-code element is available when finer filtration is needed), a square bar-scale gauge, an NPT thread (PT is the AirTAC standard, with G and NPT as order options), and a reverse/check valve. Note that no mounting bracket is included with this code. Because flow is published as curves and not a single rating, send us your application details and we will confirm sizing from the datasheet.
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 flow number. Tell us your application and air demand and we will confirm the sizing from the datasheet on request.
The A in the code means an automatic drain: collected condensate is expelled from the aluminium bowl without anyone opening it, which suits unattended installations. Differential-pressure and manual drains are also available in the GFR family as different code options.
