The AirTAC GR20006JC3TK 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 GR20006JC3TK is an AirTAC GR-series air pressure regulator for compressed air, built for one job only: holding a stable, adjustable downstream pressure. This size 200 unit has a 1/8 in NPT port and a standard regulation range of 0.05-0.9 MPa (7-130 psi). It is fitted with an external round pressure gauge scaled in bar, and the K option adds a reverse (check) valve so downstream pressure is held if the upstream supply drops. No mounting bracket is included with this configuration; the GR body can also be panel-mounted.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, thread options PT (standard), G and NPT, gauge scales in MPa, psi or bar, and an optional low-pressure type. GR units operate from -20 to 70 C, wider than the rest of the G family. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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 bench press or clamping fixture, the GR20006JC3TK sets and holds the cylinder working pressure, with the check valve keeping the clamp from relaxing if the main supply dips mid-cycle.
At a machine's valve manifold, this 1/8 in NPT regulator gives each control branch its own set pressure, with the round bar gauge letting a technician verify the setting at a glance.
On a packaging or labeling line, the unit feeds sealing arms and small gripper cylinders at a stable, repeatable pressure, protecting delicate product handling from supply-line pressure swings.
Start with the port and flow path: the 200 size with a 1/8 in NPT port suits point-of-use regulation of small actuators and valve stations; step up to 300, 400 or 600 where the line carries more air. Set the working range against the 0.05-0.9 MPa (7-130 psi) standard span, and choose the gauge scale you want to read - this unit is supplied with a round gauge in bar, while MPa and psi scales are order options. The K code means a reverse/check valve is fitted; order without K if you do not need downstream hold-up. Thread is NPT here; PT is the standard thread and G is also available. Brackets are optional (this configuration has none) and GR is also panel-mountable. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
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 curves, not as a single rated number, so there is no one figure we can quote honestly. Send us your line size and air demand and we will confirm the sizing against the datasheet curves on request before you order.
K means a reverse (check) valve is fitted. If the upstream supply fails or drops, the valve holds the regulated downstream pressure instead of letting it bleed back, which is useful on clamps, grippers and any circuit that must not lose its set pressure. The same regulator without K is available if you do not need that hold-up.
