The AirTAC GR20008JF2G 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 GR20008JF2G is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from your compressed-air supply. This 200-size unit is decodes to a G1/4 (BSPP) port, a standard regulation range of 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and a fitted embedded square gauge reading in psi. It carries no filter, no bowl and no lubricator - regulation only - and it is rated for ambient temperatures of -20 to 70 C, a wider window than the rest of the G family.
This is a genuine AirTAC part from the GR200 size class, one of four GR sizes (200/300/400/600) that step up in port and flow capacity. The range is configurable: PT (standard), G or NPT threads, MPa/psi/bar gauge scales, an optional external round gauge, a low-pressure type limited to 0.4 MPa, a reverse/check valve, and bracket or panel mounting. Flow for this series is published as curves rather than a single rating, so ask us and we will 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.

On a small bench press or clamping fixture, the GR20008JF2G sets the downstream pressure that determines cylinder thrust, with the psi gauge giving the operator a direct reading at the setpoint.
Feeding a packaging machine's valve island from a plant main at up to 1.0 MPa, this regulator holds a steady, lower supply pressure so cylinders and actuators cycle consistently.
For a lab bench or test rig running instrument-grade air at a fixed pressure, the regulator trims the supply down to the required setpoint, and the -20 to 70 C rating suits temperature-variable rooms.
Start with the port step: GR comes in 200/300/400/600 sizes with ports from 1/8" to 1", and the right size depends on the flow your line needs - since flow is published as curves rather than a single rating, send us your demand and we will confirm sizing against the datasheet before you order. Then settle the decodable options: gauge scale (MPa, psi or bar) and square embedded versus optional external round gauge; thread (PT is the standard, G and NPT are orderable options); whether you need the low-pressure L type capped at 0.4 MPa; a reverse/check valve if backflow protection matters; and bracket or panel mounting. This GR20008JF2G arrives with a square psi gauge, G1/4 thread and no bracket.
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, not as a single rated number, so we do not quote a flow figure. Tell us your application's air demand and we will confirm the datasheet flow curve and sizing for this 200-size, G1/4 regulator on request before you order.
The F2 in the code specifies the embedded square gauge with a psi scale, which is the standard fitting on GR regulators. If you prefer bar or MPa scales, or an external round gauge, those are orderable options in the same series - just specify them when ordering.
