The AirTAC GR20006LJC2TK 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 GR20006LJC2TK is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply. This unit is the low-pressure type, so its adjustment range tops out at 0.4 MPa, and it is built in the compact GR200 size with a 1/8 in NPT port. The trailing T in the code orders the NPT thread instead of the PT standard, the C2 orders an external round gauge with a psi scale, and the K orders a built-in reverse (check) valve that lets downstream air pass back through the regulator when the supply is shut off. The J code means no mounting bracket is fitted, and as a GR unit it can also be panel-mounted.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with progressively larger ports and flow capacity, and each size can be ordered as standard or low-pressure type, with or without a gauge, bracket or check valve, and in PT, G or NPT thread. AirTAC publishes regulator flow as curves rather than a single rated figure, so ask us to confirm the flow and datasheet figures for this exact model against 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.
| 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). |
| C | Gauge shape: Round. 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.

Holds the reduced air pressure feeding a heat-sealing cylinder or bladder, where the process calls for a gentle, tightly limited set-point rather than full line pressure.
Regulates the low-pressure pilot air feeding directional control valves along a conveyor line, with the check valve holding the pilot circuit charged when the main supply is isolated.
Provides a stable, low set-point air supply to instruments and test fixtures on a lab bench, read directly on the round psi gauge fitted to the unit.
Start with the port size: GR200 carries the smallest ports in the range (1/8 in here), and each step up in size buys more flow capacity, so match the size to the air demand of the circuit rather than only the pipe thread. This unit is the L (low-pressure) type, correct where the working pressure must stay at or below 0.4 MPa; for higher set-points order the standard GR type instead. The gauge is an external round unit with a psi scale; MPa and bar scales are also available, and the embedded square gauge is the standard alternative. Thread is NPT here, with PT as the catalogue standard and G (BSPP) as a further option. A mounting bracket can be added if panel mounting does not suit the install. One honest note on sizing: AirTAC publishes regulator flow as curves, not a single rated number, so send us your flow and pressure requirements and we will confirm this model is correctly sized before you order.
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 performance curves rather than a single rated figure, so no single flow number can be quoted here. Tell us your working pressure and air demand and we will confirm the flow from the datasheet for this exact model on request, before you order.
L is the low-pressure type, whose adjustment range tops out at 0.4 MPa instead of the standard GR range. C2 orders an external round gauge with a psi scale. T orders an NPT thread instead of the PT standard (G is also available). K orders a built-in reverse (check) valve that allows downstream air to flow back when the upstream supply is shut off.
