The AirTAC AirTAC GR60020JF3TK Air Pressure Regulator, NPT3/4 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 GR60020JF3TK is an AirTAC GR-series air pressure regulator in the largest 600 size, supplied with a 3/4 in NPT port. It does one job only: it reduces and holds a stable downstream pressure from a compressed-air supply, adjustable anywhere in the 0.05-0.9 MPa (7-130 psi) range, with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration carries the embedded square pressure gauge reading in bar, a built-in reverse (check) valve so downstream pressure is not lost when the upstream supply is removed, and no mounting bracket - the GR body can also be panel-mounted. As a pure regulator it contains no filter, no bowl and no drain, and it operates in ambient temperatures from -20 to 70 C, a wider window than the rest of the G family.
This is a genuine AirTAC part from the GR range, which spans 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, optional G (BSPP) or NPT threads in place of the PT standard, a low-pressure type limited to 0.4 MPa, alternate gauge scales in MPa or psi, and an external round gauge option. Flow for the 600 size is published as a curve rather than a single rated figure, so ask us and we will confirm the datasheet figures against your application before you order.

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

| K | Reverse-flow (reflux) valve fitted. |
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.

Settling a steady downstream pressure ahead of the tool-clamp and pallet-changer cylinders on a machining centre, with the check valve holding the clamp circuit's setting while the main supply is isolated for changeover.
Regulating the supply to stopper, pusher and gate cylinders on a filling or bottling conveyor, where the 3/4 in port serves a high-consumption header and the bar gauge lets technicians verify setpoints at a glance.
Dropping the factory main from header pressure to a fixed working pressure at an assembly bench or fixture station, with the reverse valve keeping the station's circuit pressurised during compressor unload or shutdown.
Step through the real choices in order. First, size and port: the 600 size with its 3/4 in port is the top of the GR range, chosen when the line's flow demand calls for the largest body - we can confirm the flow curve against your consumption before you commit. Second, gauge: this unit ships with the embedded square gauge in bar; MPa or psi scales and an external round gauge are orderable alternatives. Third, thread: PT is the catalogue standard, with G (BSPP) and NPT as orderable options - this unit is built with NPT. Fourth, the J code means no mounting bracket is fitted, though the body remains panel-mountable. The K code adds the reverse/check valve, useful when a line must hold its set pressure during supply shutdown. A low-pressure L type limited to 0.4 MPa exists if your circuit never exceeds that. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing before ordering.
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 a curve, not as a single rated number, so we do not quote a l/min, SCFM or Cv figure here. Tell us your inlet pressure, set pressure and expected air consumption, and we will confirm the datasheet curve and check the 600 size is correctly sized for your application before you order.
K means a reverse (check) valve is fitted, so the downstream circuit holds its pressure if the upstream supply is cut - order the code without K if you do not want it. The gauge choices are equally decodable: the embedded square gauge comes in MPa, psi or bar scales (this unit is bar), and an external round gauge is available as an option. Thread is PT as standard with G (BSPP) and NPT as orderable alternatives.
