The AirTAC GR20008F2G AirTAC Air Pressure Regulator, G1/4 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 GR20008F2G is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the setting you choose, and it contains no filter, no bowl and no lubricator. This unit is the 200 size with a G1/4 (BSPP) female thread, the standard regulation range of 0.05-0.9 MPa (7-130 psi), and the trailing F2 code means an embedded square gauge is fitted and scaled in psi. A mounting bracket is included, and the regulator body can also be panel-mounted. Maximum inlet pressure is 1.0 MPa (145 psi), and the GR family carries the widest temperature window in the G series at -20 to 70 C.
This is a genuine AirTAC part. The GR line spans the 200, 300, 400 and 600 sizes with matching port sizes, and the catalogue options include a low-pressure type (up to 0.4 MPa), an external round gauge, a reverse/check valve, a no-bracket version and PT, G or NPT threads. Because flow is published as curves rather than a single rated figure, we confirm the datasheet and sizing figures on request before you order.

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 and hold a repeatable clamping pressure on a workholding fixture or pneumatic press, with the fitted psi gauge giving the operator a direct readout at the setpoint.
Feed baggers, carton sealers and wrapper cylinders from a regulated branch so seal arms and pushers run at a consistent pressure independent of header fluctuations.
Regulate the supply to pick-and-place grippers on a robot cell, where gentle, repeatable part handling depends on a stable downstream pressure at the cell drop.
Pick the GR size by the port and flow your line needs: 200 is the compact step with a 1/4-class port, and 300, 400 and 600 step up in port and capacity. Set the outlet with the fitted square gauge - order scale 1 for MPa, 2 for psi or 3 for bar - or specify an external round gauge instead. If your line never exceeds 0.4 MPa, the L low-pressure type is the right variant; otherwise the standard 0.05-0.9 MPa (7-130 psi) range shown here applies. Thread is G (BSPP) on this code; PT is the catalogue standard and G/NPT are order options. A bracket is included, a no-bracket (J) version exists, and a reverse/check valve (K) can be fitted. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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-series flow as curves rather than a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Send us your line pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet curves on request before you order.
The F2 in GR20008F2G means an embedded square gauge is fitted and scaled in psi (scale 1 is MPa and 3 is bar; an external round gauge is optional). The trailing G is the thread: G1/4 means a 1/4-inch BSPP female port. PT is the catalogue standard thread, and G and NPT are options you order explicitly.
