The AirTAC GR20006LJF2T AirTAC Air Pressure Regulator, NPT1/8 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 psi) with PT1/8" 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 AirTAC GR20006LJF2T is a GR-series air pressure regulator: it does one job, holding a stable downstream pressure from your compressed-air supply. This 200-size unit carries a 1/8 in NPT port and is the low-pressure type, adjustable up to 0.4 MPa, so it suits circuits that must never see full line pressure. It is fitted with an embedded square gauge scaled in psi, has no reverse/check valve, and is supplied without a mounting bracket; the GR body is also panel-mountable. As a regulator it has no filter element, no bowl and no drain, and it handles compressed air at up to 1.0 MPa (145 psi) inlet across a -20 to 70 C range.
This is a genuine AirTAC part. The GR family spans 200, 300, 400 and 600 sizes with 1/8 in to 1 in ports, standard or low-pressure adjustment, square or round gauges in MPa, psi or bar scales, an optional reverse/check valve, and PT, G or NPT threads. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm the datasheet and flow 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.
| GR200 | G-series pressure regulator, 200 body — sets the port range. |
|---|---|
| 06 | Port size PT1/8". This body offers 06 = PT1/8", 08 = PT1/4". |
| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 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. |
| 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. |
| (blank) | No reverse-flow valve (the default). |
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 reduced, stable supply pressure feeding the control valves and small cylinders on a carton-sealing or wrapping machine, keeping actuator speeds consistent shift after shift.
Step bench compressed air down to a gentle, repeatable pressure for lab apparatus and test rigs, with the psi-scaled square gauge giving a clear reading at the panel.
Provide adjustable low-pressure air to a workbench setup used for leak-checking or function-testing small pneumatic assemblies, where the circuit must stay well below full line pressure.
Start with the port step: the 200 size takes a 1/8 in port, and larger sizes (300/400/600) step up to 1/4 in through 1 in for higher air demand - match the size to the flow your circuit needs, then ask us to confirm the flow curve. Choose the regulator type next: this L-coded unit adjusts up to 0.4 MPa for low-pressure circuits, while the standard type covers 0.05-0.9 MPa. Decide the gauge scale (this one reads psi), the thread (PT is the standard, G and NPT are order options - this unit is NPT), and whether you want a bracket fitted (this unit ships without one; GR is also panel-mountable). If your line also needs water and particulate removal or oil misting, that is a different family - a GR regulates pressure only. Before ordering, send us your application details so we can confirm sizing against the published flow curves.
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 regulator performance as flow curves rather than a single rated flow figure, so we do not quote a number here. Tell us your application and air demand and we will confirm the datasheet and the appropriate size on request before you order.
L marks the low-pressure regulator type: its adjustment range tops out at 0.4 MPa instead of the standard type's range, making it the right choice for circuits that must never be set above that level. The rest of the code decodes as 200 size, 1/8 in NPT port, no bracket, and a square gauge scaled in psi.
