The AirTAC GR40015JC2G 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 GR40015JC2G is an AirTAC GR400 series air pressure regulator for compressed air, sized for 1/2 in ports with G (BSPP) threads. It is the standard type, giving a downstream pressure adjustment range of 0.05-0.9 MPa (7-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi). This configuration is fitted with an external round pressure gauge scaled in psi, and the J code means it is supplied without a mounting bracket; the GR body is also panel-mountable. As a pure regulator it contains no filter and no bowl, and it operates across -20 to 70 C, a wider temperature window than the rest of the G-series treatment range.
This is a genuine AirTAC part from the GR family, which spans the 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in and PT, G or NPT threads. Gauge scale, low-pressure type and reverse/check valve are orderable options within the series. Flow is published in the catalogue as curves rather than a single rated figure, so ask us and we will 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 stable downstream pressure for workholding clamps and fixtures on a machining centre, with the psi-scaled round gauge giving operators a direct local readout at the machine.
Feed carton sealers, case packers and pick-and-place cylinders on a packaging conveyor from a regulated 1/2 in supply, keeping actuator speed and holding force consistent shift after shift.
Drop a branch off the main compressed-air header at a work cell and regulate it locally to the pressure the cell's tools and cylinders were designed for, protected by the 1.0 MPa maximum inlet rating.
Start with the size and port: the 400 size with a 1/2 in G-thread port sits in the middle of the GR range, and the right step up or down (200/300/400/600) depends on the flow your line needs - because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Set the downstream pressure range you need: the standard GR400 covers 0.05-0.9 MPa (7-130 psi), while a low-pressure L variant caps at 0.4 MPa. Choose your gauge: this unit carries a round external gauge in psi, and MPa or bar scales are available as alternatives. Decide the thread standard - PT is the catalogue standard, with G (BSPP) and NPT as order options - and whether you want the bracket fitted (J deletes it) or panel mounting. A reverse/check valve (K) can also be ordered if backflow protection is needed.
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 in the catalogue, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the relevant datasheet flow figures on request before you order.
This unit is fitted with an external round gauge scaled in psi; MPa or bar scales are orderable alternatives, and an embedded square gauge is the series standard. The port here is G (BSPP) thread - PT is the catalogue standard, with G and NPT available as order options. The J code means no mounting bracket is supplied, though the GR body is panel-mountable.
