The AirTAC GR30015JC2T AirTAC Air Pressure Regulator NPT1/2 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 PT1/2" 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 GR30015JC2T is an AirTAC GR300 series air pressure regulator for compressed air, built around 1/2 in NPT ports. It is a regulation-only device: it holds a steady downstream pressure set anywhere in its 0.05-0.9 MPa (7-130 psi) range, with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration carries an external round gauge scaled in psi, and is supplied without a mounting bracket, though the GR body is also panel-mountable. As a GR unit it contains no filter, no bowl and no drain, and it operates across a wide -20 to 70 C temperature span.
This is a genuine AirTAC part. The GR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, in PT (standard), G or NPT thread, with or without a bracket, with embedded square or external round gauges in MPa, psi or bar scales, and with an optional reverse/check valve or a low-pressure type limited to 0.4 MPa. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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.

Set a stable, reduced pressure feeding a pneumatic press or clamping station so the tooling cycle sees consistent force regardless of swings in the compressor header pressure.
Regulate the supply to spray guns and atomizing air lines at the pressure the gun setup calls for, with the psi-scaled round gauge giving operators a direct reading at the booth.
Feed cylinders and air-driven actuators on a packaging or cartoning machine at a controlled pressure, protecting downstream components from full header pressure.
Start with the port size: this unit steps up to 1/2 in NPT within the GR300 size, so match it to your line diameter and the flow your actuators need - we can confirm the published flow curves against your demand before you order. Set the outlet pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range; if your circuit runs below that, ask about the GR low-pressure type. Choose the gauge to suit your operators: this version has an external round gauge in psi, while embedded square gauges and MPa or bar scales are also available. Thread is PT as standard with G and NPT as orderable options - this code specifies NPT. A mounting bracket can be added if you prefer panel mounting over direct line installation, and a reverse/check valve can be fitted where you need to hold downstream pressure on supply loss.
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 one number. Tell us your line conditions and required flow and we will confirm the datasheet curve figures for the GR300 at 1/2 in ports before you order.
The C2 in the code specifies an external round gauge scaled in psi, suited to US-market panels and drawings. The same regulator can be ordered with an embedded square gauge or with MPa or bar scales if your instrumentation is metric.
