The AirTAC Airtac GR Air Regulators GR20008F2K 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 GR20008F2K is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setting you choose. This 200-size unit takes a PT1/4 (1/4 in) port, regulates from 0.05 to 0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and is the standard (non low-pressure) type. It is built for compressed air only and operates from -20 to 70 C, the widest temperature window in the G family. A square pressure gauge with a psi scale is embedded as standard, a reverse/check valve is fitted (code K) to hold downstream pressure when the supply drops, and a mounting bracket is included; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR line spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, optional G (BSPP) or NPT threads in place of the PT standard, gauge scales in MPa, psi or bar, and an optional low-pressure type. Because flow is published only as curves rather than a single rated figure, we 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.

A bench or machine press that clamps workpieces with an air cylinder needs a steady, repeatable force. This regulator holds the cylinder pressure at your set point, and the fitted check valve keeps the clamp from relaxing if the shop air main dips mid-cycle.
Carton sealers and case packers run dozens of small cylinders on 1/4 in drops. A GR200 regulator at each machine lets the setter dial in the exact pressure for gentle product handling, with the psi gauge giving a readout in the units the line crew already uses.
Robotic gripper lines on assembly cells often need pressures well below the main header. This unit steps the supply down to the gripper's setting, and the check valve holds grip pressure through brief supply interruptions so parts are not dropped.
Start with the port and size step: this unit is 200 size at 1/4 in PT, and the GR range steps up through 300, 400 and 600 for larger ports and higher flow demand - match the step to your circuit rather than oversizing blindly. Set the working pressure inside the 0.05-0.9 MPa (7-130 psi) range; if your process sits below roughly 0.4 MPa, ask about the low-pressure (L) type. Choose the gauge scale you want to read - this configuration carries psi; MPa and bar scales are order options - and note the embedded square gauge is standard with an external round gauge optional. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. The fitted reverse/check valve (K) is worth keeping if your actuators must hold position on supply loss, and the included bracket supports either standalone or panel mounting.
One honest note before you order: AirTAC publishes regulator flow as curves, not a single rated number, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you commit.
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 as characteristic curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your application flow and pressure and we will confirm the sizing against the datasheet on request.
F2 is the gauge code: a square gauge is embedded with a psi scale (MPa and bar scales are order options). K means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply is lost. Both are standard fittings on this exact configuration, not add-ons.
