The AirTAC GR30015C1T 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 GR30015C1T is a pure air pressure regulator from the GR series: it reduces and holds a stable downstream pressure from your compressed-air supply, and it does nothing else - no filter, no bowl, no lubrication. This 300-size unit is set up with 1/2 in NPT ports, a standard (non low-pressure) regulating valve, and a round pressure gauge with an MPa scale fitted so the setpoint can be read and adjusted directly at the unit. The adjustment range is 0.05-0.9 MPa (7-130 psi) with a maximum inlet (working) pressure of 1.0 MPa (145 psi), and the GR series carries the widest temperature window in the G family at -20 to 70 C (non-freezing). A mounting bracket is included, and the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR series spans four sizes (200, 300, 400, 600) with matching port sizes, and each size can be ordered with G (BSPP) or NPT threads in place of the PT standard, a square embedded gauge or an external round gauge, MPa, psi or bar gauge scales, a low-pressure (L) version limited to 0.4 MPa, a reverse/check valve (K), or no bracket (J). Flow is published by AirTAC as curves rather than a single rated figure, so tell us your application and we will confirm the sizing and datasheet figures on request before you order.

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 steady, reduced pressure feeding a machining centre's pneumatic clamp or fixture circuit, so workholding grips at the pressure the process sheet calls for instead of full line pressure.
Feed carton pick-and-place grippers and sorting fingers on a packaging conveyor at a controlled pressure, keeping suction cups and fingers from slamming parts at full supply pressure.
Regulate the compressed-air feed to a laboratory test bench or pilot rig, where each experiment needs its set pressure dialled in and held while instruments run downstream.
Pick the GR size by the port and flow step your line needs: 200, 300, 400 or 600, with ports stepping from 1/8 in up to 1 in - this 300 unit lands on 1/2 in NPT. Choose the gauge that matches your practice: the square embedded gauge or the external round gauge, with MPa, psi or bar scales (this code carries a round, MPa-scale gauge). Thread is PT as the standard, with G (BSPP) and NPT as catalogue options - this unit is the NPT version. If your circuit never needs more than 0.4 MPa, the low-pressure L type is available; add K if you want a reverse/check valve fitted, or J to order without the bracket. Flow is published as curves, not a single rating, so 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-series flow as curves rather than a single rated figure, so we do not quote a rated flow number for this unit. Send us your line pressure, set pressure and the air demand of your equipment, and we will confirm the sizing against the datasheet curves on request before you order.
C means the external round gauge is fitted and the scale digit 1 sets it to MPa, so the GR30015C1T arrives with a round MPa-scale gauge for reading your setpoint. If you prefer psi or bar, or the square embedded gauge instead, those are catalogue options on the same regulator - just tell us which scale you want and we will confirm the right code.
