The AirTAC GR30015C2K AirTAC Air Pressure Regulator PT1/2 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 GR30015C2K is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setting you choose. This size 300 unit has a PT1/2 (1/2 in) port, a standard regulation range of 0.05-0.9 MPa (7-130 psi), and a maximum inlet pressure of 1.0 MPa (145 psi). The C2 code means an external round gauge with a psi scale is fitted, and the K code means a reverse (check) valve is built in, so downstream pressure will not back-drive through the unit when the upstream supply is removed. It works on compressed air only, from -20 to 70 C - a wider temperature window than the rest of the G family.
This is a genuine AirTAC part. The GR range runs from size 200 to 600, so you can step port size up or down as your air demand grows, with G (BSPP) and NPT thread options to order alongside the standard PT, an optional low-pressure type (up to 0.4 MPa), and a choice of gauge scale. GR units include a mounting bracket and are also panel-mountable. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 and hold a stable clamping pressure on a bench or C-frame pneumatic press, with the check valve keeping the set pressure in the clamp line if the main supply drops.
Feed carton sealers, case packers or wrap stations on a packaging line, giving each machine its own regulated air supply independent of the header pressure.
Take a 1/2 in branch off the factory air main and regulate it down to the working pressure a cell or workstation needs, with the psi gauge readable at the point of use.
Pick the GR size by port and expected air demand: this unit is size 300 with a PT1/2 port; smaller and larger sizes (200/400/600) cover lighter and heavier circuits. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering. Choose the gauge scale you want (MPa, psi or bar) - this unit is fitted with a round psi gauge. Select the thread to match your piping: PT is the standard here, with G (BSPP) and NPT available as order options. If your circuit can back-feed, keep the K reverse/check valve this unit carries; order a code without K if you do not need it. A mounting bracket is included, and GR is also panel-mountable.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. 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 flow figure. Tell us your application and we will confirm the flow curve and correct size from the datasheet on request before you order.
C2 means an external round pressure gauge with a psi scale is fitted; MPa and bar scales are available as other codes. K means a reverse (check) valve is fitted, so downstream pressure cannot back-drive through the regulator when the upstream supply is removed. Both are decodable choices you select at order time.
