The AirTAC GR30015F2K 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 GR30015F2K is an AirTAC GR-series air pressure regulator, a regulation-only unit: it reduces and holds downstream air pressure and does not filter or lubricate the air. This configuration is the GR300 size with a PT1/2 (1/2 in) PT-thread 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). It carries an embedded square pressure gauge scaled in psi, a reverse/check valve on the outlet side, and a mounting bracket; the GR series is also panel-mountable. Its operating temperature range is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR family is available in sizes 200, 300, 400 and 600 with matching port sizes, and options include G (BSPP) or NPT threads to order, a low-pressure type limited to 0.4 MPa, a round external gauge in MPa, psi or bar scales, and no-gauge or no-bracket variants. Flow is published 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.

Drops the plant air pressure to the set working level for a pneumatic press or clamping station, with the check valve helping hold the set downstream pressure if the supply side dips.
Regulates the air feeding cylinders on a packaging or bottling conveyor line, keeping actuator speed and gentle product handling consistent as header pressure fluctuates.
Sets a stable, lower pressure at the air drop feeding a machine tool's pneumatic circuits, with the square psi gauge giving the operator a direct local pressure readout.
Choose the GR series by size and port step against the air demand of the circuit: sizes 200, 300, 400 and 600 step up in port and flow capacity, and this GR30015F2K sits at the 300 size with a PT1/2 port. Set the outlet pressure with the adjustment range in mind: the standard type covers 0.05-0.9 MPa (7-130 psi), while the low-pressure L type is limited to 0.4 MPa if your circuit never needs more. Decide the gauge: the embedded square gauge is standard on this unit and this one is scaled in psi, with optional round external gauges in MPa, psi or bar. Other decodable choices are the reverse/check valve (fitted on this model, code K), the thread (PT is standard; G/BSPP and NPT are order options), and the bracket (included here; the GR can also be panel-mounted). One honest note on sizing: flow for the GR series is published as curves, not a single rating, so send us your required flow and pressure and we will confirm the correct size against the datasheet before you order.
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 figure, so we do not quote one number here. Tell us your required flow and working pressure and we will confirm the sizing against the datasheet on request before you order.
The F2 in the code means this unit carries the embedded square gauge scaled in psi (MPa and bar scales are also available, and a round external gauge is optional). The K means a reverse/check valve is fitted on the outlet side. The port is PT1/2 with standard PT thread; G (BSPP) and NPT threads are available as order options.
