The AirTAC GR40010C2T 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 GR40010C2T is a compressed-air pressure regulator in the GR400 size, fitted with a 3/8 in NPT port. It reduces and holds a stable downstream pressure anywhere in the 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 standard type and carries an external round gauge scaled in psi, so operators can read and set line pressure directly at the unit. A mounting bracket is included, and the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family is regulation only: it contains no filter element and no bowl, so it is used where air is already filtered and only pressure control is needed. The series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, with gauge scale, thread option and bracket choices to match. 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.

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 a consistent working pressure to a bench or inline pneumatic press so forming and staking operations repeat the same force from cycle to cycle, read directly off the round psi gauge.
Regulate the air feeding conveyor-mounted diverters, stoppers and pusher cylinders on a packaging line, keeping actuation pressure stable as upstream compressor output fluctuates.
Drop into a machine-builder's air preparation panel as the pressure-control stage downstream of an existing filter, with the included bracket or panel mounting and a psi gauge to suit US service crews.
Start with the port and size step: the GR400 in 3/8 in NPT suits lines sized for that connection, and stepping up a size gives more flow capacity where the curve demands it. Choose the gauge scale to match your plant standard - MPa, psi or bar - and the thread to match your piping: PT is the standard, with G (BSPP) and NPT as orderable options. A mounting bracket is included if you want the unit off the manifold, and the GR can also be panel-mounted. Because flow is published as curves rather than a single rated figure, 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, not as a single rated number, so we do not quote a flow figure. Tell us your line pressure, set pressure and expected air demand, and we will confirm the datasheet curve and correct size for your application on request.
In the GR code, C2 selects the external round gauge with a psi scale, and the trailing T selects NPT threading. Both are catalogue options: the gauge can be ordered in MPa, psi or bar scales, and the port can be specified as PT (the standard), G (BSPP) or NPT to match your piping.
