The AirTAC GR20008F3T AirTAC Air Pressure Regulator NPT1/4, 200 Size 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 GR20008F3T is an AirTAC GR200 series air pressure regulator: a regulation-only unit for compressed air with no filter element and no bowl. This configuration is decoded as a 200 size body with a 1/4 in NPT thread, a standard adjustment range of 0.05-0.9 MPa (7-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), and an embedded square pressure gauge reading in bar. An external round gauge is available as an option if you prefer a different style.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with larger ports and greater flow capability at each step, plus options including G (BSPP) or NPT threads in place of the PT standard, a low-pressure type limited to 0.4 MPa, a reverse/check valve, a no-bracket version, and gauge scales in MPa, psi or bar. GR units operate from -20 to 70 C, wider than the rest of the G series. Flow is published as curves rather than a single rating, so 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.

| F | Gauge shape: Square. C is round, F is square. |

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 stable, repeatable supply pressure to the clamp and wrap cylinders on a carton-sealing line, so jaw timing and grip force stay consistent shift after shift.
Hold the atomizing-air pressure steady at the spray guns in a finishing booth, where a drifting supply pressure shows up directly as a changed fan pattern.
Regulate the air feeding a small bench pneumatic press or clamping fixture, letting the operator dial in and lock the working force for the part in hand.
Start with the port: this unit is 1/4 in NPT, so match it to the line size or step up a size (300/400/600) if the circuit needs more flow capacity - the catalogue publishes flow as curves, not one rated number, so ask us to confirm sizing against your demand before ordering. Set the working pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range; if your process must run at or below 0.4 MPa, the GR low-pressure (L) type is the better fit. Choose the gauge scale (MPa, psi or bar) to suit your operators, and pick the thread: PT is the catalogue standard, with G (BSPP) and NPT as order options - this unit is already NPT. A bracket is included and GR is also panel-mountable; a no-bracket (J) version exists if you mount it differently.
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 GR flow as curves, not as a single rated figure, so we do not quote a number. Tell us your line size and air demand and we will confirm the datasheet flow curve for this 1/4 in NPT, 200 size regulator on request before you order.
The code decodes it that way: the F3 in GR20008F3T selects the embedded square gauge with a bar scale (MPa and psi scales are also available), and the trailing T selects NPT threading. PT is the catalogue standard thread and G (BSPP) is the other option - all are order specifications, not stock claims.
