The AirTAC GR60025LC2T AirTAC Air Pressure Regulator NPT1 Low-Pressure is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 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 GR60025LC2T is an AirTAC GR-series air pressure regulator in the largest 600 size, fitted with a 1 in NPT port. It performs one job only: holding a stable downstream pressure from your compressed-air supply. This is the low-pressure (L) type, so the setting range goes up to 0.4 MPa, and the C2 code adds an external round gauge with a psi scale so operators can read and adjust the setpoint directly. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -20 to 70 C, and the unit includes a mounting bracket; GR bodies are 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 to 1 in, standard or low-pressure regulation, gauge or no-gauge builds, psi/MPa/bar scale choices, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

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.

Feeds a packaging machine section that must run at a gentle, stable pressure below 0.4 MPa, with the round psi gauge letting line staff read and reset the setpoint during changeover.
Sits ahead of low-pressure clamping or holding actuators on a machining fixture, where the operator dials in the holding pressure on the psi gauge and the regulator holds it steady.
Installed on a 1 in NPT branch off the main plant air header to give one production cell its own independent, low-pressure supply instead of tapping the header pressure directly.
Pick the GR size by the port and flow step your line needs: 200 for 1/8-1/4 in ports up to 600 for 3/4-1 in ports, with larger sizes carrying more flow. This unit is already the low-pressure (L) type, correct where the downstream setpoint must stay at or below 0.4 MPa; the standard GR type covers the wider range if your process needs it. Choose the gauge scale that matches your plant instruments - psi here, MPa or bar on other builds - and specify PT (standard) or G/NPT thread to match your piping. A bracket is included and GR bodies can also be panel-mounted. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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 GR flow as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
The L in the code marks the low-pressure regulator type: its adjustment range goes up to 0.4 MPa, instead of the wider range of the standard GR build. It suits circuits that must never be set above 0.4 MPa. The C2 code adds an external round gauge with a psi scale so the setpoint can be read directly.
