The AirTAC GR30010C1T AirTAC Air Pressure Regulator NPT3/8 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 PT3/8" 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 GR30010C1T is a genuine AirTAC air pressure regulator in the GR300 series, built to reduce and hold a stable downstream pressure from a compressed-air supply. This configuration is the 300 size with a 3/8 in NPT port and the standard regulator type, adjustable from 0.05 to 0.9 MPa (7-130 psi), with a maximum working (inlet) pressure of 1.0 MPa (145 psi). A round external pressure gauge with an MPa scale is fitted, so the set pressure can be read and adjusted directly at the unit. As a regulator, it carries no filter, no bowl and no drain - its single job is precise pressure control.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with port sizes from 1/8 in to 1 in, and options including G or NPT thread variants, low-pressure type, a check (reverse-flow) valve, gauge scale in MPa, psi or bar, and bracket or no-bracket mounting; the GR is also panel-mountable. GR units operate from -20 to 70 C, a wider temperature window than the rest of the G family. Flow is published in the catalogue as curves rather than a single rated figure, so we 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.

Set and hold the clamping or forming pressure on a pneumatic press circuit, with the round MPa gauge giving the operator a direct readout of the set pressure at the machine.
Regulate the supply pressure feeding cylinders and grippers on a packaging or cartoning line, keeping actuator forces consistent as the compressor output fluctuates through the shift.
Take a branch off a plant air main and step the pressure down to the level a work cell or machine station was designed for, with the 3/8 in NPT port matching standard drop piping.
Start with the port step: this 300-size unit takes a 3/8 in port, and moving up or down a size (200/300/400/600) changes both the port and the flow path, so size against the air demand of the circuit rather than the pipe alone. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering. Then settle the decode choices: thread (PT is the standard; G and NPT are order options - this unit is the NPT variant), gauge type and scale (embedded square as standard, external round optional, in MPa, psi or bar - here a round MPa gauge is fitted), the low-pressure type if you need settings below the standard range, and whether a reverse/check valve is required. A bracket is included with this unit, and the GR can also be panel-mounted.
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 performance curves in the catalogue rather than a single rated figure, so there is no one flow number we can honestly quote. Tell us your application and air demand and we will confirm the datasheet figures and check the sizing for you before you order.
The trailing T in GR30010C1T decodes to an NPT thread on the 3/8 in port. PT is the standard thread across the GR series, with G (BSPP) and NPT available as order options - so if your piping is PT or G, that variant can be specified instead. The thread choice is a specification, not a delivery matter.
