The AirTAC GR20008C2K AirTAC Air Pressure Regulator PT1/4 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 PT1/4" 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 GR20008C2K is an AirTAC GR-series air pressure regulator, a genuine AirTAC part dedicated to regulation only: it steps the compressed-air supply down to a stable, adjustable working pressure for downstream equipment. This 200-size unit is configured with PT1/4 (1/4 inch) ports, PT thread as standard, a standard regulation range of 0.05-0.9 MPa (7-130 psi), a round external pressure gauge scaled in psi, and a built-in reverse (check) valve that holds the downstream setting when upstream pressure is lost. Maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -20 to 70 C, wider than the rest of the G family. A mounting bracket is included, and the GR body is also panel-mountable.
The GR family is offered in four sizes (200, 300, 400, 600) with ports from 1/8 to 1 inch, so you can step up in port size as your air demand grows. Options include a low-pressure type, gauge scale in MPa, psi or bar, G (BSPP) or NPT threads, and a reverse/check valve. Because AirTAC publishes flow performance as curves rather than a single rated figure, we confirm the datasheet and flow 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.

Set a repeatable clamping or forming pressure for a bench pneumatic press, with the check valve holding the setting if shop-air pressure dips mid-cycle.
Feed carton sealers, label heads and wrapping arms at a fixed, adjustable pressure so cylinders and air cylinders stroke consistently across shifts.
Regulate the drop lines serving impact drivers, nut runners and air ratchets at a workbench, keeping tool pressure within the setting chosen for each task.
Start with the port and size step: the 200 size carries 1/4 inch PT ports here, and larger sizes (300/400/600) move up to 1/2, 3/4 and 1 inch as your flow demand rises. Set the adjustment range against your circuit: this standard type covers 0.05-0.9 MPa (7-130 psi), while a low-pressure (L) variant is available up to 0.4 MPa. Choose the gauge scale to suit your team - MPa, psi or bar - and note this unit ships with the external round gauge in psi. The fitted reverse/check valve (code K) is worth specifying wherever a brief upstream pressure loss must not dump the downstream setting. Thread is PT as standard; G (BSPP) and NPT are orderable options, and a bracket is included. 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 regulator flow performance as curves rather than a single rated number, so we do not quote a flow figure. Tell us your inlet pressure, set pressure and expected air consumption, and we will confirm the flow curve and datasheet figures for this exact model on request.
In the code GR20008C2K, C2 indicates the external round pressure gauge scaled in psi (MPa and bar scales are also available), and K indicates a fitted reverse/check valve, which holds the downstream pressure setting if upstream supply pressure is lost. The gauge is optional on the GR series; a square embedded gauge is the alternative.
