The AirTAC GR30015C2T 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 AirTAC GR30015C2T is a compressed-air pressure regulator in the GR300 size, decodes to a 1/2 in NPT port, and does one job only: it holds a stable downstream pressure from the compressed-air supply. The setpoint is adjustable across 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the unit is rated for -20 to 70 C, the widest temperature window in the G-series. This configuration carries a round pressure gauge reading in psi, and the mounting bracket is included; the GR300 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 to 1 in, gauge scales in MPa, psi or bar, optional G or NPT threads in place of the PT standard, and an optional reverse/check valve. Flow for this size is published as curves rather than a single rated figure, 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.

Set and hold the working pressure feeding an air-over-oil or double-acting cylinder on a bench press or riveting station, so the forming force stays repeatable from cycle to cycle.
Regulate the supply to carton-closing cylinders, clamps and diverters on a packaging conveyor, keeping actuator speeds consistent as the main header pressure wanders.
Drop the header pressure to a safe, stable working level at the point of use on a production-floor air drop, protecting downstream tools and cylinders from supply surges.
Start with the port step: the GR300 with its 1/2 in connection sits in the middle of the GR range (200/300/400/600), and the right size depends on the air demand of the circuit downstream - flow is published as curves, not a single rating, so have us check the curve against your consumption before you order. Then set the gauge: this code specifies a round external gauge on the psi scale; MPa and bar scales are also available. Thread is the next real choice - PT is the catalogue standard, while G (BSPP) and NPT (as on this model, suffix T) are order options. A mounting bracket is included as standard, and the suffix J variant omits it if you are panel-mounting.
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 performance curves rather than a single rated number, so we do not quote a flow figure for this unit. Send us your application's air demand and we will confirm the sizing from the GR300 datasheet curves before you order.
The C2 code on GR30015C2T specifies an external round gauge reading in psi. Gauge scales are a real ordering choice on the GR series: 1 = MPa, 2 = psi, 3 = bar. If your plant gauges read in bar or MPa, order the matching suffix instead - the regulator itself is identical.
