The AirTAC GR40015C2G AirTAC Air Pressure Regulator, G1/2 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 GR40015C2G is an AirTAC GR-series air pressure regulator for compressed air, built on the 400 size body with a 1/2 in port threaded G (BSPP). It does one job only: holding a stable downstream pressure set anywhere in the 0.05-0.9 MPa (7-130 psi) range, with a maximum inlet (working) pressure of 1.0 MPa (145 psi). This configuration carries the external round pressure gauge scaled in psi, and the standard (non-low-pressure) regulator type. There is no filter, no bowl and no drain on a GR - it is regulation only, so pair it with upstream filtration where the air needs cleaning.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, an optional low-pressure type limited to 0.4 MPa, an optional reverse/check valve, gauge scales in MPa, psi or bar, and a bracket included as standard (GR is also panel-mountable). Rated flow for the GR400 is published as curves rather than a single figure - ask us and we will confirm the datasheet numbers against your application.

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 repeatable downstream pressure for a 1/2-in-line pneumatic press or clamping fixture, so forming and holding forces stay consistent from cycle to cycle while the round psi gauge gives the operator a direct readout.
Feed carton sealers, case packers and wrapper cylinders from a regulated 1/2 in branch, keeping wrapper tension arms and pusher cylinders at a fixed setting regardless of header pressure swings in the plant ring main.
Regulate the air to hold-down rollers, diverters and stop-gate cylinders on a packaging or bottling conveyor line, with the psi gauge letting line technicians verify the setting during changeover without a separate test rig.
Start with the port and size step: the GR400 with its 1/2 in G thread sits in the middle of the 200/300/400/600 range - step up or down if your line porting or expected air demand calls for it, and let us check the published flow curves against your consumption before you order. Choose the gauge to suit the operator: this model has the external round gauge in psi; MPa and bar scales are alternatives, and the embedded square gauge is the other style. Thread is your call at order time - PT is the catalogue standard, with G (this unit) and NPT as options. The standard type covers the full 0.05-0.9 MPa setting range; specify the L low-pressure type instead if you must never exceed 0.4 MPa. A reverse/check valve (code K) can be fitted to hold downstream pressure on supply loss, and the bracket is included as standard. Flow is published as curves, not a single rating, so ask us to confirm sizing against the 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 GR400 flow as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and air consumption, and we will confirm the datasheet curve data against your application on request before you order.
The C2 code on GR40015C2G specifies the external round pressure gauge scaled in psi. If your team works in metric, the same regulator can be ordered with an MPa or bar scale, or with the embedded square gauge instead - just ask for the equivalent code when you enquire.
