The AirTAC GR40015C1T 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 GR40015C1T is an AirTAC GR-series air pressure regulator: its only job is to hold a steady, adjustable downstream pressure from your compressed-air supply. This is the size 400 unit with 1/2 in NPT ports, the standard regulator type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and a maximum inlet pressure of 1.0 MPa (145 psi). The C1 suffix means an external round pressure gauge with an MPa scale is fitted, so the set pressure can be read directly at the unit. As a pure regulator it contains no filter, no bowl and no drain, and it performs no lubrication.
This is a genuine AirTAC part. The GR family is offered in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT threads, gauge scales in MPa, psi or bar, a low-pressure type, and an optional reverse/check valve, so the same regulator concept can be scaled across your air network. Flow is published as curves rather than a single rated figure, so send us your application details and we will confirm the sizing and datasheet figures 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 machining cell where air clamps and pneumatic press cylinders grip parts, the GR40015C1T holds a fixed, repeatable set pressure so every clamp closes with the same force, cycle after cycle.
Feeding the cylinders and air actuators on a carton or bottle packaging line, this 1/2 in regulator keeps the downstream pressure stable even as the supply pressure wanders, so sealing and diverting motions stay consistent.
At a 1/2 in drop from a factory air main serving a work bay or machine group, the GR40015C1T lets each area set and read its own working pressure independently of the header, with the round MPa gauge showing the setting at a glance.
Pick the GR size by the port and flow step you need: 200, 300, 400 or 600, with this unit stepping up to 1/2 in NPT ports - size up if your line demand sits near the top of a smaller unit's curve. Choose the gauge scale (MPa, psi or bar) to match how your technicians read pressure, and decide between the embedded square gauge or the external round gauge fitted here. Thread is a real order choice: PT is the standard, with G (BSPP) and NPT as catalogue options - this unit carries NPT. GR is also panel-mountable, and the bracket is included on this configuration.
One honest routing note: AirTAC publishes regulator flow as curves, not a single rated number, so we do not quote a flow figure here. Tell us your line pressure and demand and we will confirm the correct size against the datasheet before you order.
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 a flow number for this unit. Send us your inlet pressure, set pressure and expected air demand, and we will confirm the correct size against the datasheet on request before you order.
C1 means an external round pressure gauge with an MPa scale is fitted, so you can read the regulated pressure directly at the unit; square embedded gauges and psi or bar scales are the other catalogue choices. T means the 1/2 in ports are NPT thread - PT is the standard thread option, with G (BSPP) also available to order.
