The AirTAC GR60025JC1T AirTAC Air Pressure Regulator NPT1 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 GR60025JC1T is an AirTAC GR600 series air pressure regulator for compressed air, built around the largest size in the GR range with 1 in NPT ports. It is a regulation-only unit: there is no filter, no bowl and no lubricator in this family, so it belongs downstream of any filtration in your circuit. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), accepts a maximum inlet pressure of 1.0 MPa (145 psi), and operates from -20 to 70 C - a wider temperature window than the rest of the G-series treatment units. This configuration carries the C option: an external round pressure gauge with an MPa scale, fitted so the set pressure is readable at the unit. The J option means no mounting bracket is supplied; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and can be ordered with G (BSPP) or NPT threads instead of the PT standard, with or without a gauge, as a low-pressure type (up to 0.4 MPa), or with a reverse/check valve. Flow figures for the GR600 are published in the catalogue as curves rather than a single rated number, so ask us and we will confirm the datasheet figures against 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. |

| C | Gauge shape: Round. 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.

Set a stable working pressure at the point where a plant's 1 in main distribution line feeds a production bay, holding the downstream circuit at its set pressure regardless of swings at the compressor room.
Regulate the air feeding a large pneumatic press or clamping fixture, where the operator sets and reads the working pressure locally on the fitted MPa round gauge before each run.
Trim the supply pressure to quarter-turn pneumatic actuators on a process skid, keeping the actuator torque output consistent as the header pressure varies through the day.
Size and port are the first decision: the GR600 with its 1 in NPT connection is the right step when the line volume is large, and the smaller 200/300/400 sizes cover lighter circuits - match the size to the flow your line needs rather than to the pipe alone. The adjustment range here is the standard 0.05-0.9 MPa (7-130 psi); if your setpoint sits at or below 0.4 MPa, the L low-pressure variant of the same family is worth considering. Gauge choices are an embedded square gauge or an external round gauge, each available with MPa, psi or bar scales - this unit is built with the round gauge on an MPa scale, and other scale codes can be ordered. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also available as an order option. The J code means no bracket is fitted, and the K reverse/check valve option was not taken on this unit.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated figure, so we do not quote a flow number here. Send us your line conditions and we will confirm the datasheet curve 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 GR-series flow as curves in the catalogue, not as a single rated figure, so we do not quote a flow number for this regulator. Tell us your line size, inlet pressure and set pressure, and we will confirm the datasheet curve for the GR600 against your application on request.
The C in the code GR60025JC1T means an external round pressure gauge is fitted, and the 1 sets its scale to MPa. The GR family can alternatively be ordered with an embedded square gauge, and either gauge style is available with MPa, psi or bar scales - just ask for the scale code you need when ordering.
