The AirTAC GR60020F3T AirTAC 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 GR60020F3T is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setting you choose, and it contains no filter, no bowl and no lubricator. This is the largest 600 size with a 3/4 in NPT port, the standard pressure type, and a square pressure gauge fitted and scaled in bar. Maximum inlet pressure is 1.0 MPa (145 psi), the adjustment range is 0.05-0.9 MPa (7-130 psi), and the regulator is rated for -20 to 70 C - a wider temperature window than the rest of the G family. A mounting bracket is included, and the unit is also panel-mountable.
This is a genuine AirTAC part. The GR line spans four sizes (200, 300, 400, 600) with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a low-pressure type (L) rated up to 0.4 MPa, an optional reverse/check valve (K), and gauge scales in MPa, psi or bar. Flow for the GR series is published as curves 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.

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

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.

On a 3/4 in main drop feeding pneumatic clamp cylinders on a machining fixture, this regulator holds the clamping pressure at a fixed setting so every cycle grips with the same force, cycle after cycle.
Mounted on the 3/4 in branch line that supplies a cartoning or case-packing machine, the GR60020F3T steps plant supply down to the pressure the machine's cylinders and actuators were designed for, with the bar-scale square gauge giving operators a local reading.
Where a row of pneumatic gate, diverter or stopper valves shares one 3/4 in supply in a bulk-handling or conveyor system, this regulator keeps the actuation pressure stable so valve stroke times stay consistent across the line.
Start with the size and port: 200 through 600 step up in both port size and flow capacity, so match the 3/4 in NPT port here to your main air line and let the required flow drive the size choice. Then set the gauge: this unit ships with the embedded square gauge scaled in bar, and MPa or psi scales are available if your team reads in those units. Thread is a real decision - PT is the catalogue standard, while G (BSPP) and NPT (as on this model) are specified at order time. A low-pressure L variant (up to 0.4 MPa) and a reverse/check valve (K) are also decodable options, and a mounting bracket is included as standard. Because GR flow is published as curves rather than a single rating, send us your flow and pressure requirements and we will confirm sizing from the datasheet before you order.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR-series flow as curves rather than a single rated figure, so there is no one flow number we can quote honestly. Send us your line pressure, set pressure and expected air demand, and we will confirm the flow figures from the datasheet against your application before you order.
Yes. The embedded square gauge is standard, and the scale is a decodable choice: 1 = MPa, 2 = psi and 3 = bar, so the F3 in GR60020F3T is the bar-scaled square gauge. An external round gauge is also available as an option. Specify the scale you want when ordering.
