The AirTAC GR20008JF2GK 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 GR20008JF2GK 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 carries a 1/4 in port with G (BSPP) thread, and as a standard-type regulator it covers an adjustment range of 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). The code confirms a built-in reverse/check valve (K), a fitted square pressure gauge reading in psi, and no mounting bracket - the GR body is also panel-mountable. Because it is a pure regulator, there is no filter bowl, no drain and no lubricator in this unit; it regulates pressure only. It handles compressed air from -20 to 70 C, a wider temperature window than the rest of the G family.
This is a genuine AirTAC part. The GR line spans 200, 300, 400 and 600 sizes with port options from 1/8 to 1 in, a low-pressure type (L) rated to 0.4 MPa, gauge scales in MPa, psi or bar, and PT, G or NPT threads to order. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application 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.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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 stamping or assembly cell where clamp cylinders must close at a repeatable set pressure, this GR200 regulator holds the downstream line steady at the operator's setting, with the check valve holding the circuit against backflow.
Carton sealers and wrapper stations run air cylinders all day; a 1/4 in regulator at each machine's air drop lets the technician dial in the exact working pressure for gentle product handling without disturbing neighbouring machines.
Robot end-effector grippers need a lower, tightly held pressure than the plant main; panel-mount this GR200 at the gripper manifold and set the safe gripping force point on its square psi gauge.
Start with the port step: GR200 is the 1/4 in size in the GR range (200/300/400/600), so step up a size if your line's flow demand outgrows 1/4 in piping - and let us check the published flow curve against your consumption, since AirTAC does not publish a single rated-flow number for these regulators. Set your adjustment window against the range: this standard type covers 0.05-0.9 MPa (7-130 psi); the L low-pressure variant tops out at 0.4 MPa if your process runs gentler. Choose the gauge scale you want to read - this unit ships with the embedded square gauge in psi, with MPa or bar scales and an external round gauge available. Thread is G (BSPP) here; PT is the catalogue standard and NPT is an order option, so pick the one your piping actually uses. The K code means a reverse/check valve is already fitted - useful where backflow could disturb the setting. No bracket is included with this code, but the GR body can be panel-mounted; order the bracket variant if you want stand-alone mounting.
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 curves, not as a single rated figure, so there is no one number we can honestly quote. Send us your application details and we will confirm the datasheet flow curve for this 1/4 in GR200 unit so you can size it against your air consumption before ordering.
K means a reverse/check valve is fitted, so air cannot flow back through the regulator and disturb your set pressure. The gauge on this unit is the embedded square type reading in psi; MPa or bar scales, an external round gauge, and PT or NPT threads instead of G are all catalogue options - tell us which you need when ordering.
