The AirTAC GR20008JF2TK 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 GR20008JF2TK is an AirTAC GR200 air pressure regulator for compressed air with a 1/4 in NPT port. It reduces and holds a stable downstream pressure anywhere in its 0.05-0.9 MPa (7-130 psi) adjustment range, with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration carries an embedded square gauge scaled in psi and a built-in reverse (check) valve that lets downstream air pass back when the upstream supply is removed. No mounting bracket is supplied, and the GR can also be panel-mounted.
This is a genuine AirTAC part. The GR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, in PT (standard), G or NPT thread, with gauge and scale options and an optional low-pressure type limited to 0.4 MPa. Operating temperature is -20 to 70 C, wider than the rest of the G family. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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. |

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 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 a steady, reduced pressure feeding the gripper cylinders on a robotic pick-and-place cell so delicate parts are handled without over-clamping.
Regulate the supply branch feeding the cylinder actuators on a bottling line so sequencing valves and clamps see consistent pressure shift after shift.
Trim the bench air supply on a laboratory test rig down to the exact pressure a test calls for, reading the setpoint on the psi-scaled square gauge.
Choose the GR size by the port and flow your line needs: 200 is the compact step with a 1/4 in port here, and larger sizes (300/400/600) carry bigger ports for higher flow - we confirm exact flow against the published curves before you order. Pick the gauge scale (MPa, psi or bar) and, if you want downstream air to vent back through the unit on exhaust, the K reverse/check valve option. Thread is NPT on this model; PT is the standard and G is also orderable. A mounting bracket is optional, and GR is panel-mountable. If your circuit never exceeds 0.4 MPa, ask about the L low-pressure type.
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 a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow from the datasheet before you order.
K marks a fitted reverse (check) valve: downstream air can flow back through the regulator when the upstream supply is removed. Models without K have no check valve. This unit also carries a square gauge scaled in psi and uses a 1/4 in NPT port.
