The AirTAC GR20008JF2T AirTAC Air Pressure Regulator, NPT1/4 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 GR20008JF2T is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady at the setting you choose. This 200-size unit carries a 1/4 in NPT port, a standard regulation range of 0.05-0.9 MPa (7-130 psi), and a built-in square pressure gauge scaled in psi so the setting is readable at the panel. Maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -20 to 70 C, wider than the rest of the G family. As a pure regulator it contains no filter, no bowl and no drain, so it is fitted where air is already clean or where regulation alone is required.
This is a genuine AirTAC part. The GR line runs from size 200 to 600 with port sizes from 1/8 in to 1 in, and options include a low-pressure type, a reverse/check valve, alternative gauge scales (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 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.

| (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.

Set a steady downstream pressure for the clamping cylinders on a machining centre, so workholding force stays consistent from first cut to last without drifting as shop air pressure moves.
Regulate the air feeding pick-and-place cylinders and diverters on a packaging conveyor, keeping actuator speeds repeatable across a shift even as the compressor loading cycles.
Feed positioners and air-operated valves on a process skid from a dedicated regulated branch, so each actuator sees the pressure its positioner was set up for, independent of header swings.
Size and port step up together: 200 through 600, with ports from 1/8 in to 1 in, so pick the size whose flow curve covers your demand rather than oversizing on port alone. The standard range of 0.05-0.9 MPa (7-130 psi) covers most general plant air; a low-pressure type is available where settings stay below 0.4 MPa. Choose the gauge scale you want to read - MPa, psi or bar - and note the embedded square gauge is standard with an external round gauge optional. Thread is PT as standard; G and NPT are catalogue options to order, as is the reverse/check valve. A mounting bracket is optional and GR is also panel-mountable. Because flow is published as curves, not a single rating, 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, not as a single rated number, so there is no honest one-line figure to quote. Send us your demand and we will confirm the flow from the datasheet for this 200-size, NPT1/4 unit on request before you order.
This code carries a square gauge scaled in psi, fitted as standard. GR regulators can alternatively be specified with an MPa or bar scale, and an external round gauge is also available as an option - just order the code with the scale digit you want.
