The AirTAC GR60020JF2K AirTAC Air Pressure Regulator PT3/4 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 psi) with PT3/4" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR60020JF2K is an AirTAC GR-series air pressure regulator for compressed air only. It does one job: holding a steady downstream pressure from a variable supply. This size 600 unit carries a PT3/4 (3/4 in) port with PT thread as standard, regulates from 0.05 to 0.9 MPa (7-130 psi), and is built for the widest temperature window in the G family at -20 to 70 C. The embedded square gauge reads in psi, and a reverse/check valve (code K) is fitted to hold downstream pressure when the upstream supply is lost. No bracket is included with this configuration, and as a GR unit it contains no filter, no bowl and no drain.
This is a genuine AirTAC part from the GR600 series, the largest regulator size in the G line, with G (BSPP) and NPT thread options available to order. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm flow and datasheet figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with 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 rather than from a single rated figure.

Dropping a 3/4 in plant air header down to a stable working pressure for a production hall distribution loop, with the check valve holding the circuit's set pressure during upstream dips.
Regulating the compressed air feed to a machining centre's pneumatic valves and clamping circuits, where a steady setpoint protects tool-change and workholding actuation.
Supplying regulated air to conveyor stopper cylinders and packaging machinery actuators, with the psi gauge giving operators a direct local readout of the set pressure.
Sizing a GR regulator starts with the port step: sizes 200, 300, 400 and 600 map to increasing port sizes from 1/8 in up to 1 in, so pick the size whose port matches your line and let the published flow curves confirm it covers your demand - we will check the curve against your application before you order. This unit is the standard type with a 0.05-0.9 MPa (7-130 psi) adjustment range; a low-pressure type (L) limited to 0.4 MPa exists if your setpoint is lower. Gauge choices are the embedded square gauge (standard, this unit in psi scale) or an optional external round gauge, with MPa, psi or bar scales. Thread is PT as standard on this model, with G (BSPP) and NPT as orderable options; a bracket is optional (this configuration omits it) and GR units are also panel-mountable. A reverse/check valve can be factory-fitted, as it is here with code K.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes regulator flow as curves rather than a single rated figure, so we do not quote one number. Tell us your inlet pressure, set pressure and expected air demand, and we will confirm the flow from the datasheet curve for this exact model before you order.
K is the reverse/check valve code: this regulator is factory-fitted with a check valve that holds downstream pressure if the upstream supply fails. It is an orderable option on GR regulators - codes without K are supplied without it. Note also the F2 in the code: a square embedded gauge with a psi scale, and J meaning no mounting bracket is included.
