The AirTAC GR60025F3T AirTAC Air Pressure Regulator NPT1 (1 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 PT1" 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 GR60025F3T is an AirTAC GR-series air pressure regulator in the largest 600 size, fitted with 1 in NPT ports. It does one job only: reducing and holding a stable downstream pressure from a compressed-air supply. The standard-type regulator adjusts from 0.05 to 0.9 MPa (7-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi), and this configuration carries the embedded square pressure gauge with a bar scale. As a regulator it has no filter bowl and no lubricator, so it is normally installed after filtration in the air line. It operates in ambient temperatures from -20 to 70 C, a wider range than the rest of the G-series family.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G (BSPP) or NPT thread, with gauge scale options, a low-pressure type, an optional reverse/check valve, and bracket or panel mounting. Flow 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. 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.

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 plant's 1 in compressed-air main to a controlled header pressure that feeds an entire production bay, with the bar-scale gauge read directly at the header.
Holding a repeatable clamping pressure on the air supply to a pneumatic press or forming station, so every cycle clamps at the same set point.
Regulating the supply line to packaging and palletising conveyors so divertors, stoppers and pushers act at a consistent, non-jarring pressure.
Start with the port step: this unit is the 600 size with 1 in NPT ports, the largest in the GR range, so match it to the main-line pipe diameter and the flow your line actually draws - we can check the published flow curves against your demand before you order. Set the downstream pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range; if your process sits below 0.4 MPa, ask about the low-pressure L type. Choose the gauge scale you want to read at the panel (MPa, psi or bar - this unit is bar) and the thread family: PT is the catalogue standard, while G (BSPP) and NPT are orderable options such as the NPT on this code. A mounting bracket is included and GR can also be panel-mounted. Note that GR pressure loss is low, but no single rated flow figure is published - confirm sizing with us before ordering.
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 regulator flow as curves rather than a single rated figure, so we do not quote a rated l/min, m3/h or SCFM number. Send us your line pressure, set pressure and expected air demand, and we will confirm the flow curve and sizing from the datasheet on request before you order.
The F3 in GR60025F3T means the embedded square gauge is fitted with a bar scale (MPa, psi and bar scales are available on other codes), and the trailing T means 1 in NPT ports. PT is the catalogue standard thread, while G (BSPP) and NPT are orderable options - this code is the NPT version.
