The AirTAC GR20008JF1TK 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 GR20008JF1TK is an AirTAC GR-series air pressure regulator for compressed air only. It reduces and holds a stable downstream pressure adjustable from 0.05 to 0.9 MPa (7-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration is the GR200 size with 1/4 in NPT ports, the standard (non low-pressure) type, an embedded square gauge scaled in MPa, and a built-in reverse (check) valve so downstream pressure is held if the upstream supply is lost. No mounting bracket is fitted; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans the 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 in, and options include G (BSPP) or NPT threads in place of the PT standard, an external round gauge, psi or bar gauge scales, a low-pressure type limited to 0.4 MPa, and a bracket. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing against your application and we will supply the datasheet 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.

| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 steady clamp-cylinder pressure on a robotic welding cell so grip force stays repeatable from part to part; the check valve holds the setting if the main air supply drops.
Regulate the shop-air feed to a machining centre's pneumatic actuators and tool-change circuits, keeping downstream pressure stable despite swings in the workshop supply.
Trim the supply pressure to pick-and-place cylinders and grippers on a packaging conveyor so stroke speeds stay consistent across a shift without touching each flow control.
Choose the GR size by the port step your air line needs: 200 (1/8-1/4 in), 300 (3/8-1/2 in), 400 (3/4 in) and 600 (1 in), stepping up where higher flow is expected. Decide the gauge scale (MPa, psi or bar) and whether the embedded square gauge or the optional external round gauge suits your panel. Set the thread to match your piping: PT is the standard, with G (BSPP) and NPT as catalogue options to order. Add the K option if you want a reverse/check valve, the L type if the circuit never exceeds 0.4 MPa, and the J code if you do not want a bracket. Flow is published as curves, not a single rating, so ask us to confirm sizing against the application before ordering.
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 rather than a single rated figure, so we do not quote a l/min, SCFM or Cv number. Tell us your line size and expected demand and we will confirm sizing against the datasheet on request.
K means a reverse (check) valve is fitted, so downstream pressure is held if the upstream supply is lost. F1 means the embedded square gauge is included, scaled in MPa; psi or bar scales and an external round gauge are catalogue options.
