The AirTAC GR30015C2TK 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 GR30015C2TK is an AirTAC GR-series air pressure regulator for compressed air only. It does one job: holding a stable downstream pressure setting regardless of swings in supply pressure. This 300-size unit is configured with a 1/2 in NPT port, an external round pressure gauge reading in psi, and a built-in reverse (check) valve that lets downstream air back-flow past the regulator when the upstream side is vented or shut off. The standard-type regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with a maximum inlet (working) pressure of 1.0 MPa (145 psi), and it operates from -20 to 70 C - the widest temperature window in the G family. A mounting bracket is included, and the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, gauge scales in MPa, psi or bar, an optional low-pressure type (up to 0.4 MPa), and G (BSPP), NPT or PT threads. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet flow 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 steady downstream pressure feeding a bank of directional control valves on an automated line, so cylinder speeds and valve switching behaviour stay consistent across shifts.
Regulate the air feeding a bench-mounted pneumatic clamp or small press, where the operator dials in a fixed setpoint on the psi gauge and the check valve holds the circuit when supply is dropped.
Feed air knives or blow-off nozzles along a packaging conveyor at a set pressure, with the regulator keeping the jet force uniform regardless of compressor load swings.
Sizing a GR regulator starts with the port step: size 200 covers 1/8-1/4 in, size 300 covers 3/8-1/2 in, size 400 covers 1/2-3/4 in, and size 600 covers 1 in - step up a size when your line demand sits near the top of a size's flow curve. This unit already carries the choices that matter here: NPT thread (PT is the standard thread; G and NPT are the catalogue options to order), a round psi gauge for US-style readouts, a check valve for vented downstream circuits, and the standard adjustment range of 0.05-0.9 MPa. If your setpoint never exceeds 0.4 MPa, the GR low-pressure type (code L) is the alternative to specify. One honest note on sizing: flow for this series is published as curves, not a single rating, so send us your application details and we will confirm the right 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, not as a single rated number, so we do not quote a figure here. Tell us your line pressure, setpoint and downstream demand, and we will confirm the flow data from the datasheet for this exact model on request.
C is the external round pressure gauge (the embedded square gauge is the standard option), 2 is the psi scale (1 = MPa, 3 = bar), and K means a reverse/check valve is fitted, allowing back-flow from the downstream side. The 15 decodes to a 1/2 in NPT port on the 300 size.
