The AirTAC GR60020JF1TK AirTAC Air Pressure Regulator NPT 3/4 in 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 GR60020JF1TK is an AirTAC GR600 air pressure regulator for compressed air, built around a 3/4 in NPT port for larger supply lines. This configuration is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), and an operating temperature of -20 to 70 C - the widest temperature window in the G series. The embedded square pressure gauge (MPa scale) lets you read and set downstream pressure directly, and the fitted reverse/check valve holds the downstream setting if upstream supply is interrupted. No mounting bracket is fitted; the GR600 is also panel-mountable.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with matching port sizes, and options include a mounting bracket, alternative gauge scales (MPa, psi or bar), a low-pressure type limited to 0.4 MPa, and PT, G or NPT threads ordered to specification. Flow for this regulator is published as curves rather than a single rated figure, so ask us and we will confirm the 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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| 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.

Set and hold a stable downstream pressure feeding the clutch and counterbalance cylinders of a mechanical stamping press, with the check valve preserving the setting during supply dips.

Supply positioners and piston actuators on a plant valve rack at a controlled pressure, using the wide -20 to 70 C range for outdoor or unheated installation points.
Start with the port step: the GR series steps through 1/8 in to 1 in across sizes 200 to 600, and the larger the size, the larger the port and the greater the flow capacity - match the 3/4 in NPT port of this GR600 to your line size and demand. Decide on the gauge scale (this unit is MPa; psi and bar scales are orderable), whether you want the reverse/check valve (fitted here as code K), and whether a bracket is needed for wall or panel mounting. Thread is a specification choice: PT is the standard, with G (BSPP) and NPT available as order options - this unit is NPT. Note that GR is regulation only: it has no filter bowl and no lubricator, so pair it with GF and GL units if your circuit needs filtration or oil mist. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 GR regulator flow as performance curves, not as a single rated figure, so we do not quote a flow number here. Tell us your line pressure, set pressure and air demand, and we will confirm the datasheet curve figures for this 3/4 in GR600 on request before you order.
K means a reverse/check valve is fitted, which holds the downstream pressure setting if the upstream supply drops. The gauge on this unit is the embedded square type with an MPa scale; psi and bar scales are available as order options, and PT, G or NPT threads are specification choices when ordering.
