The AirTAC GR40015F2T 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 GR40015F2T is an AirTAC GR-series air pressure regulator for compressed air: it holds a stable downstream pressure set anywhere in its 0.05-0.9 MPa (7-130 psi) adjustment range, with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration is the size 400 body with a 1/2 in NPT port, the standard regulator type, a factory-fitted embedded square gauge scaled in psi, and the mounting bracket included; the body is also panel-mountable. Operating temperature is -20 to 70 C, the widest range in the G family.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with matching port sizes, and is orderable with G (BSPP) or NPT threads in place of the PT standard, MPa/psi/bar gauge scales, a low-pressure type limited to 0.4 MPa, a reverse/check valve, or no gauge. Flow is published as curves rather than a single rating, 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.

| F | Gauge shape: Square. C is round, F is square. |

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 working pressure feeding a pneumatic press or clamping fixture, with the psi-scaled square gauge giving the operator a direct reading at the setpoint.
Regulate the supply to a packaging machine's cylinders and actuators, using the 1/2 in NPT port to sit inline on the machine's main air drop.
Feed a robotic gripper or tool-clamp circuit on a CNC cell, holding a repeatable downstream pressure so part handling stays consistent shift to shift.
Choose the GR size by the port and flow your line needs: sizes 200, 300, 400 and 600 step up in port and capacity, with this size 400 unit carrying a 1/2 in port. Decide the gauge scale (MPa, psi or bar) to match the instruments already on the machine, the thread family (PT standard, G or NPT to order), and whether the standard type or the low-pressure type (up to 0.4 MPa) suits the circuit. A reverse/check valve and the no-gauge or bracketless variants are also decodable options.
One honest note on sizing: AirTAC publishes regulator flow as curves, not a single rated figure, so we do not quote a number here. Ask us to confirm the flow and datasheet details 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 regulator flow as curves rather than a single rated figure, so we do not state a number here. Tell us your application and we will confirm the flow and full datasheet details for the GR40015F2T on request.
In this code, F is the square gauge and 2 is the psi scale, so the GR40015F2T ships with the embedded square gauge reading in psi. MPa and bar scales are catalogue options, as is ordering the regulator with no gauge at all.
