The AirTAC GR20006JC2GK AirTAC Air Pressure Regulator G1/8 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 GR20006JC2GK is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady, and it does nothing else - no filter, no bowl, no lubricator. This GR200 unit is set up with a G1/8 (BSPP) port, a standard regulation range of 0.05-0.9 MPa (7-130 psi), a round pressure gauge reading in psi, and a built-in reverse (check) valve so downstream pressure will not back-feed through the unit. It is supplied without a mounting bracket, and GR bodies can also be panel-mounted. Maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line runs from size 200 up to 600 with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with round or square gauges in MPa, psi or bar scales, a low-pressure type option and an optional reverse valve. 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.

On a CNC fixture line, the GR20006JC2GK sits at the take-off for the clamp cylinders, holding a steady clamping pressure at the 1/8 in branch while the check valve stops the circuit bleeding back if upstream supply dips.
Compact grippers and small actuators on an assembly cell need a stable, low-flow regulated supply; this 1/8 in regulator mounted on the valve manifold feed keeps gripper force consistent part after part.
Blow-off and air-sensor nozzles along a packaging conveyor are fussy about supply pressure; a local GR200 regulator at the nozzle header lets the line set its own pressure independently of the main drop.
Start with the port step: GR200 covers the small end of the range at 1/8 in, and larger sizes (300/400/600) step up in port and flow capacity - match the size to the air your circuit actually consumes. This unit carries a round gauge on a psi scale; square gauges and MPa or bar scales are available if you prefer. The trailing G in the code specifies a G (BSPP) thread - PT is the standard thread for this series, with G and NPT as order options, so confirm which your pipework needs. The J code means no mounting bracket is fitted; add a bracket code if you want panel or surface fixing instead. The K code fits a reverse (check) valve - useful where a trapped downstream pressure must not push back through the regulator. If your circuit runs at low set pressures, ask about the GR low-pressure type (L), which regulates up to 0.4 MPa.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated number, so we will not quote you a flow figure here. Tell us your application and we will confirm the sizing against the datasheet curves 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 characteristic curves rather than a single rated figure, so we do not quote a flow number on the page. Send us your set pressure and expected consumption and we will confirm the datasheet curve figures for this exact unit on request before you order.
In the GR code, C selects the round (external) gauge style, the digit 2 sets the psi scale, and K specifies a built-in reverse (check) valve. So GR20006JC2GK arrives with a psi-reading round gauge fitted and a check valve that blocks back-flow from the downstream side. Square gauges and MPa or bar scales, and a unit without the check valve, are available as other code options.
