The AirTAC GR20006JC1TK 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 GR20006JC1TK is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setting you choose while upstream supply pressure wanders. This 200-size unit is threaded 1/8 in NPT and is the standard (not low-pressure) type, with an adjustment range of 0.05-0.9 MPa (7-130 psi) and a maximum inlet pressure of 1.0 MPa (145 psi). The C1 in the code means a round external gauge scaled in MPa is fitted, and the K means a reverse (check) valve is built in, so downstream pressure is held if the supply side drops. The J code means no mounting bracket is supplied; the GR body is also panel-mountable. As a regulator it contains no filter and no bowl, and it lubricates nothing.
This is a genuine AirTAC part. The GR family runs from size 200 to 600, covering ports from 1/8 in to 1 in, with optional G (BSPP) or NPT threads, an optional low-pressure type limited to 0.4 MPa, gauge scale choices of MPa, psi or bar, and an optional reverse valve. Operating temperature for GR is -20 to 70 C, wider than the rest of the G family. Rated flow is published as curves rather than a single 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.

On a small pneumatic bench press or clamping fixture, the GR20006JC1TK sets and holds the working pressure that determines clamping force, with the check valve holding the setting if shop air dips mid-cycle.
At a spray gun or air-assisted applicator, this 1/8 in NPT regulator gives the operator a dedicated, gauge-read pressure setting independent of the shared shop-air header, so finish settings stay repeatable.
Feeding positioners or pilot-air circuits on automated process valves, the regulator keeps the control-air pressure within the range the actuator manufacturer expects, with the MPa gauge giving a local reference reading.
Start with the port: this unit is 1/8 in NPT, and the GR family steps through 200/300/400/600 sizes up to 1 in, so pick the size whose flow curve covers your air demand rather than matching pipe size alone. Choose the gauge scale you want to read (MPa, psi or bar) and whether you want the standard embedded square gauge or the external round gauge fitted here. Thread is a real order choice: PT is the catalogue standard, with G (BSPP) and NPT available as coded options - this unit is NPT. Decide on the reverse/check valve (fitted here, coded K) if your circuit must hold downstream pressure on supply loss, and on the bracket if you want body-mounted fixing (this unit has none; GR is also panel-mountable). If your line never exceeds 0.4 MPa, the L low-pressure type is an alternative. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing 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 in the catalogue, not as a single rated number, so we will not quote a figure that is not on the datasheet. Tell us your application and air demand and we will confirm the flow and sizing figures from the datasheet on request before you order.
C1 means a round external gauge scaled in MPa is fitted (square embedded gauge is standard; psi or bar scales are options), and K means a reverse/check valve is built in. Both are real order choices on the GR family, along with thread (PT standard, G or NPT) and bracket - this unit has no bracket, as coded J.
