The AirTAC GR30015C1TK 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 GR30015C1TK is an AirTAC GR-series air pressure regulator for compressed air, and regulation is all it does: there is no filter element, no bowl and no drain in this unit. This 300-size configuration is threaded 1/2 in NPT (PT is the standard thread; G and NPT are catalogue options to order), is the standard (non low-pressure) type, and carries a fitted reverse/check valve so downstream pressure is held if the upstream supply drops. It is supplied with an external round pressure gauge scaled in MPa, while an embedded square gauge is the standard alternative. Maximum inlet pressure is 1.0 MPa (145 psi), the adjustment range is 0.05-0.9 MPa (7-130 psi), and the operating temperature is -20 to 70 C - a wider window than the rest of the G family. A mounting bracket is included, and GR regulators are also panel-mountable.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with matching port sizes, and options include thread choice (PT, G or NPT), gauge scale (MPa, psi or bar), a low-pressure type limited to 0.4 MPa, and a reverse/check valve. Flow figures for this series are published as curves rather than a single rated number, 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 a stable, reduced pressure to the air cylinder of a bench or C-frame press so clamping and forming strokes are repeatable, with the check valve holding the set pressure if the shop supply dips mid-cycle.
Feed carton sealers, case packers and wrapping machines at a controlled pressure below the main header, protecting cylinders and valve islands tuned for a lower set point.
Regulate the supply to gripper cylinders on an assembly or material-handling cell so part handling force stays consistent across shifts, with the bracket taking the mounting load near the tool.
Start with the port step: 300-size GR regulators take 1/2 in ports, and the size you choose should follow the air consumption of the circuit rather than the pipe you happen to have - step up to 400 or 600 if the demand is high, down to 200 if it is light. Because flow is published as curves and not as a single rated figure, ask us to confirm sizing against your application before ordering. Then settle the decode choices: gauge scale (MPa, psi or bar; this unit ships with a round MPa gauge), thread (PT is the standard, G and NPT are order options), the reverse/check valve (fitted here, code K), and the bracket (included; GR is also panel-mountable). If your set pressure never exceeds 0.4 MPa, the L low-pressure type is an alternative.
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 rather than a single rated number, so there is no one l/min or SCFM figure we can honestly quote. Tell us your application and we will confirm the datasheet flow curve and sizing on request before you order.
K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply is lost. C1 means the external round gauge is included, scaled in MPa; psi and bar scales are the other catalogue options.
