The AirTAC GR20006LJC2GK AirTAC Air Pressure Regulator, G1/8 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 GR20006LJC2GK is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from your compressed-air supply. This unit is the low-pressure type, so its adjustment range tops out at 0.4 MPa - suited to circuits that must never see full line pressure. It is built in size GR200 with a G1/8 (1/8 inch) BSPP port, and the code confirms a round external gauge with a psi scale, a built-in reverse/check valve so downstream pressure is held if the supply drops, and no mounting bracket (the GR series is also panel-mountable). Max 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.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with matching port sizes, and can be ordered as standard or low-pressure type, with or without a gauge (square MPa, psi or bar scales), with or without a reverse/check valve, with or without a bracket, and with PT (standard), G or NPT threads. Because flow is published as curves rather than a single rating, 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. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| G | G (BSPP) 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.

Sealing jaws and light clamping fixtures on packaging lines need a firm but limited force. This low-pressure regulator caps the setting at 0.4 MPa, and the fitted check valve holds the set pressure if the main air supply dips mid-cycle.
Directional valves and pilot circuits on a machine's control panel often need a stable, reduced pressure independent of the main line. The 1/8 inch G-thread port and panel-mountable GR200 body drop straight into a compact panel build, with the psi gauge giving operators a local readout.
Filling and positioning aids on food and beverage lines run on gentle, precisely held air pressure. This regulator trims the supply down to the low range the tooling needs, and the -20 to 70 C rating suits washdown-adjacent areas and cold rooms.
Start with the size and port: GR200 with a 1/8 inch connection suits smaller lines - step up through 300, 400 and 600 if your line and flow demand a larger port. This code is the low-pressure (L) type, capped at 0.4 MPa; choose the standard type if you need the full 0.05-0.9 MPa range. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. The K code adds a reverse/check valve - useful where downstream pressure must be retained. Thread here is G (BSPP); PT is the standard thread with G and NPT as orderable options. A bracket is optional on GR, which is also panel-mountable.
One honest note before you order: AirTAC publishes regulator flow as curves, not a single rated figure, so we cannot quote you a rated flow number. Send us your line size and flow requirement and we will confirm the right size against the datasheet 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 curves, not as a single rated number, so we do not quote a rated flow, Cv or l/min figure for this unit. Tell us your line size and required flow and we will confirm the sizing against the datasheet on request before you order.
The L code makes this the low-pressure type: its adjustment range tops out at 0.4 MPa instead of the standard GR range of 0.05-0.9 MPa, and max inlet pressure is still 1.0 MPa (145 psi). The C2 code fits an external round gauge reading in psi (MPa and bar scales are also available), and the K code adds a reverse/check valve so downstream pressure is retained if the supply is lost. Thread is G (BSPP); PT is the standard thread, with G and NPT as orderable options.
