The AirTAC GR40015C2T 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 GR40015C2T is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply. This is the size 400 body with 1/2 in NPT ports, the standard regulation type covering 0.05-0.9 MPa (7-130 psi), and it is configured with the external round pressure gauge on the psi scale so setpoints can be read and adjusted directly at the unit. The trailing T in the code specifies NPT thread; PT is the standard thread form and G (BSPP) is also a catalogue option. 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 spans four sizes (200, 300, 400, 600) with matching port sizes, and options include a low-pressure type limited to 0.4 MPa, gauge scale choice (MPa, psi or bar), a reverse/check valve, and panel mounting - the GR is also panel-mountable in addition to its bracket mounting. Rated flow is published as curves rather than a single figure, so ask us to confirm flow and datasheet details 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 a stable, reduced pressure feeding a bench or C-frame pneumatic press so the forming or staking force stays repeatable from cycle to cycle, with the psi gauge letting operators verify the setpoint at the machine.
Regulate the air feeding cylinders, diverters and clamp actuators on a packaging or cartoning line, keeping actuator speeds consistent as the header pressure from the compressor room fluctuates.
Supply hold-down pads, pushers and diverters on a conveyor line at a controlled pressure, so product handling is gentle and repeatable without overdriving the cylinders.
Size the GR400 by the port and flow step first: sizes 200, 300, 400 and 600 step up in port size and flow capacity, and this unit sits at the 1/2 in (NPT) level - match it to the line size and the air demand of the circuit. Set the downstream pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range; if your process runs below that, the low-pressure L type (up to 0.4 MPa) is the alternative. Choose the gauge scale to suit your team - this unit carries the round gauge on psi, with MPa and bar available. Thread is NPT here; PT is the standard form and G (BSPP) can be ordered. A reverse/check valve can be fitted if backflow protection is needed. Because flow is published as curves and not a single rated number, send us your application details and we will confirm sizing 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, not as a single rated figure, so we do not quote a number here. Send us your line size and air demand and we will confirm the flow curve and datasheet figures for the GR400 at 1/2 in NPT on request.
The C2 in the code specifies the optional external round gauge on the psi scale. The embedded square gauge is the standard fitting, and scales of MPa, psi or bar can be ordered - just tell us which scale your team reads when you enquire.
