The AirTAC GR20006C3TK AirTAC Air Pressure Regulator NPT1/8 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 PT1/8" 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 GR20006C3TK is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply, and it carries no filter element and no bowl. This 200-size unit is specified with a 1/8 in NPT 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). A round pressure gauge scaled in bar is fitted so the setpoint can be read directly, and the K code means a reverse (check) valve is built in, holding the downstream setting if the upstream supply is interrupted. The mounting bracket is included, and GR bodies are also panel-mountable. Operating temperature is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line spans 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, gauge scales in MPa, psi or bar, a low-pressure type option, and PT, G or NPT threads to order. 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.

Dropping shop-air pressure to the stable level a packaging machine's cylinders and actuators were designed for, with the bar-scale gauge letting an operator read and hold the setpoint at the machine.
The 200 size and 1/8 in port suit tight control panels and small manifolds where a compact regulator with an included bracket keeps the branch circuit at its own pressure, independent of the main header.
On a line where the upstream supply is switched between cycles, the fitted reverse/check valve keeps the regulated downstream circuit from losing its setting, so tooling stays charged and ready.
Pick the GR size by the port and flow step you need: this 200 size takes a 1/8 in NPT port, and the range steps up through 300, 400 and 600 as flow demand grows. Choose the gauge scale to match your plant convention - MPa, psi or bar - this unit carries the round gauge in bar. The trailing T sets the NPT thread; PT is the standard and G (BSPP) is also a catalogue option. The K code adds a reverse/check valve, useful where a held downstream setting matters, and the bracket is included with panel mounting also possible.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated number, so we do not quote a flow figure here. Send us your line pressure, set pressure and expected air demand 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 regulator flow as performance curves rather than a single rated figure, so we do not quote a flow number here. Tell us your inlet pressure, set pressure and air demand and we will confirm the sizing against the datasheet on request.
K means a reverse (check) valve is fitted. If the upstream supply drops or is shut off, the valve helps hold the downstream pressure so your regulated setting is not lost. If you do not need that behaviour, the same regulator is available without the check valve.
