The AirTAC GR20006C3T 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 GR20006C3T is an AirTAC GR200 series air pressure regulator, a genuine AirTAC part built for one job: holding a steady, adjustable downstream pressure from a compressed-air supply. This configuration decodes to the 200 size with an NPT1/8 (1/8 in) port, the standard regulator 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 C3 suffix in the code specifies a round external gauge fitted with a bar scale, and the standard build includes a mounting bracket, so the unit can be screwed to a panel or machine frame as well as plumbed in-line. GR series units are rated for ambient and medium temperatures of -20 to 70 C, a wider window than the rest of the G family, and the regulator body carries no filter, no bowl and no lubricator - it is regulation only.
This is a genuine AirTAC component. The GR family spans the 200, 300, 400 and 600 sizes with port sizes stepping up from 1/8 in to 1 in, and options include G (BSPP) or NPT thread in place of the PT standard, an embedded square gauge or an external round gauge in MPa, psi or bar scales, a low-pressure type limited to 0.4 MPa, a reverse/check valve, and a no-bracket build. AirTAC publishes flow for the GR series as curves rather than a single rated figure, so if you need a flow or sizing number for your line, ask us and we will confirm the datasheet 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 GR20006C3T sits upstream of the cylinder valve and holds the clamping pressure steady at the setpoint the operator dials in, so cycle-to-cycle clamp force does not drift as the compressor load changes.
On a carton-sealing or labelling machine with small air cylinders and actuators, this 1/8 in port regulator feeds a dedicated branch, letting the machine builder set a gentle, repeatable working pressure for delicate product handling independent of the main header pressure.
On a wire-cutting or cable-stripping station that uses small pneumatic grippers and hold-downs, the GR20006C3T regulates the branch feeding those tools, and the fitted round bar gauge gives the operator a clear local readout of the set pressure.
Start with the size and port: the GR200 sits at the small end of the GR range, and the right step depends on the flow your circuit actually draws - stepping up to GR300, GR400 or GR600 buys larger ports and more flow capacity. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing against the datasheet before you order. Then settle the decodable choices: this unit is the standard type with a 0.05-0.9 MPa (7-130 psi) range (a low-pressure L type limited to 0.4 MPa exists if your circuit sits lower); the round bar gauge fitted here can be swapped for a square gauge or a different scale (MPa, psi or bar); the NPT thread on this code is an order option - PT is the catalogue standard and G (BSPP) is also available; and the bracket is included unless you specify the J no-bracket build. GR is also panel-mountable. If you need a reverse/check valve, that is a separate code option - this unit does not carry one.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes flow for the GR series as characteristic curves rather than a single rated figure, so there is no one rated-flow number we can honestly quote. Tell us your application - supply pressure, set pressure and the air your circuit consumes - and we will confirm the sizing against the datasheet curves on request before you order.
C specifies the optional external round gauge (the standard build has an embedded square gauge), and the 3 sets its scale to bar; MPa or psi scales are available as alternate codes. The rest of the code decodes as: GR200 series, 1/8 in port, T for NPT thread (PT is the catalogue standard, G/BSPP also available), standard pressure type, bracket included, no reverse valve.
