The AirTAC GR20006LJC1T AirTAC Regulator NPT1/8 Low-Pressure MPa Gauge 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 GR20006LJC1T is an AirTAC GR-series air pressure regulator: it does one job only, holding a stable downstream pressure from your compressed-air supply. This is the low-pressure type, with an adjustment range up to 0.4 MPa, in the compact GR200 size with a 1/8 in NPT port. An external round pressure gauge with an MPa scale is fitted so the set pressure can be read directly, and the unit is supplied without a mounting bracket. As a regulator it contains no filter and no water bowl, so it neither removes water nor adds oil mist. Maximum 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 line is published in GR200, GR300, GR400 and GR600 sizes with 1/8 in to 1 in ports, standard or low-pressure adjustment, gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for 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. |
| 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. |
| (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.

On a small assembly bench where soft-jaw or rubber-pad clamps must grip without crushing, the GR20006LJC1T holds the fixture circuit at a set pressure at or below 0.4 MPa, with the fitted MPa gauge letting the operator verify the setting at a glance.
Bench rigs that bubble-test or actuate small sample cylinders need a gentle, repeatable supply. This low-pressure regulator on a 1/8 in NPT drop keeps the test circuit in its working band, and the -20 to 70 C range covers unheated lab spaces.
Auxiliary jets on spinning and weaving machines often run at modest pressures independent of the main header. A GR200 low-pressure regulator on each auxiliary branch lets the line set its own pressure without disturbing the plant supply.
Start with the port step: GR200 with a 1/8 in port suits the smallest branch circuits; step up to GR300/GR400/GR600 when the line diameter and air demand grow. Because this is the L (low-pressure) type, choose it where the working pressure must stay at or below 0.4 MPa; the standard GR covers 0.05-0.9 MPa. Pick the gauge scale you want to read (MPa, psi or bar) and the thread family your piping uses - PT is the standard, with G and NPT as orderable options. A mounting bracket can be added if the unit will not be panel-mounted.
One honest note on sizing: AirTAC publishes regulator flow as curves, not as a single rated number, so we do not quote a flow figure here. Send us your line size and air demand and we will confirm the right GR size against the datasheet before you order.
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 flow as curves, not as a single rated figure, so we do not quote a flow number for this unit. Tell us your line size and air demand and we will confirm the datasheet flow curve for the GR200 against your application before you order.
L marks the low-pressure type: its adjustment range tops out at 0.4 MPa instead of the standard GR range, which is what you want on circuits that must never see full line pressure. C1 means an external round gauge with an MPa scale is fitted; psi and bar scales are available on other variants.
