The AirTAC GR30015C2 AirTAC Air Pressure Regulator PT1/2 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 GR30015C2 is an AirTAC GR300 air pressure regulator, built to do one job: hold a steady, adjustable downstream pressure from a compressed-air supply. This configuration carries a PT1/2 port, the standard-type regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi), and a maximum inlet pressure of 1.0 MPa (145 psi). It is fitted with an external round pressure gauge read in psi, and the mounting bracket is included - the GR family is also panel-mountable. Because it is a pure regulator, there is no filter, no bowl and no drain: pair it upstream with a filter if the air needs cleaning.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, G or NPT thread variants, low-pressure and standard types, gauge choices and scale options, and an optional reverse/check valve. Flow figures are published as curves rather than a single rated number, so ask us and we will confirm the datasheet 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.

On a machine-tool press line, the GR30015C2 holds a fixed clamping pressure at the PT1/2 feed to the cylinders, so every cycle closes with the same setpoint instead of drifting with shop-air swings.
On a carton sealer or wrap station, this regulator sets the actuator supply for the sealing heads and product stops, keeping the line's motion consistent through a full shift.
At a 1/2 in plant-air drop feeding an assembly cell, the GR30015C2 steps the header pressure down to the working pressure the cell's tools and grippers were designed around, with the psi gauge giving operators a visible setpoint.
Start with the port and size: this unit is the 300 size at PT1/2, one step up in port and flow capacity from the 200/1/4 in class - match the size to the air demand of the circuit rather than the pipe alone. Set the downstream pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range; if your process runs below that band, ask about the GR low-pressure type. Choose the gauge to suit the operator: this version has an external round gauge in psi, while an embedded square gauge and MPa or bar scales are also available. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and the bracket is included.
One honest note before you order: AirTAC publishes regulator flow as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application's air demand and we will confirm sizing against the datasheet before you commit.
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 regulator flow as performance curves rather than a single rated number, so we do not state a flow figure here. Tell us your application's air demand and we will confirm the sizing against the datasheet on request.
The C2 code on GR30015C2 specifies an external round gauge with a psi scale. An embedded square gauge, and MPa or bar scales, are available options in the GR family - specify the gauge code you want when ordering. The pressure gauge reads downstream setting only; it does not change the 0.05-0.9 MPa adjustment range.
