The AirTAC GR60025C1T AirTAC Air Pressure Regulator NPT1 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 GR60025C1T is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply, and it carries no filter, bowl or lubricator. This size 600 unit is the largest step in the GR range, with a 1 in NPT port for high-capacity mains and headers. It is the standard type with a regulation range of 0.05-0.9 MPa (7-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), and it works in ambient conditions from -20 to 70 C - the widest temperature window in the G family. A round pressure gauge scaled in MPa is fitted so the set point can be read at a glance, and a mounting bracket is included; the GR series is also panel-mountable.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and the catalogue offers choices you can order against this code: G (BSPP) or NPT thread in place of the PT standard, gauge scales in MPa, psi or bar, a low-pressure type limited to 0.4 MPa, and a reverse (check) valve option. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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 1 in compressed-air header down to a controlled working pressure for a production hall section, with the round MPa gauge giving operators a visible set point at the wall-mounted station.
Feeding a bank of solenoid valves on an automated machine at a steady, repeatable pressure so cylinder speeds and valve actuation stay consistent across every cycle of the shift.
Regulating the air to pop-up diverters, stoppers and gate cylinders on a packaging or distribution conveyor line, where a stable set point keeps product handling gentle and repeatable.
Start with the port and size step: GR comes in 200, 300, 400 and 600, and the 600 size with its 1 in connection suits the largest branch lines - match the step to the flow your line actually draws, since the catalogue publishes flow as curves rather than one rated number. Then set the regulation window: this standard type covers 0.05-0.9 MPa (7-130 psi); if your circuit never needs more than 0.4 MPa, the low-pressure (L) type is the alternative. Choose the gauge scale you want - MPa, psi or bar - and the thread: PT is the standard, with G (BSPP) and NPT available as order options, which is how this unit carries its NPT1 port. A reverse (check) valve can be fitted if you need the downstream side held if supply is lost. Because flow figures are curves, not a single rating, ask us to confirm sizing against your application 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 regulator flow as curves, not as a single rated number, so we do not state a flow figure here. Tell us your line pressure, set pressure and the flow your equipment draws, and we will confirm the sizing from the datasheet on request before you order.
PT is the standard GR thread, but G (BSPP) and NPT are catalogue options you can order - the T in GR60025C1T is what specifies NPT, giving the 1 in connection shown. The gauge scale is also a choice: MPa, psi or bar, with this unit fitted with a round gauge scaled in MPa.
