The AirTAC GR20006LJC3T AirTAC Low-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 GR20006LJC3T is an AirTAC GR-series air pressure regulator in the compact size 200, built purely for pressure regulation - it contains no filter, no bowl and no lubricator. This configuration decodes as the low-pressure type, so it regulates outlet pressure up to 0.4 MPa, with a maximum working (inlet) pressure of 1.0 MPa (145 psi). The ports are NPT1/8 (1/8 in), the trailing T in the code selecting the NPT thread option. It is fitted with an external round gauge on the bar scale, and the J code means no mounting bracket is included, though GR units are also panel-mountable. Operating temperature is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, in standard and low-pressure types, with G (BSPP), NPT or PT threads, gauge choices and bracket options. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet 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.

|---|---|
| 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. |
| 3 | Gauge scale: bar. 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.

Packaging machines often use air clamps and hold-downs that must not be squeezed too hard. This low-pressure GR regulator holds a gentle, stable setpoint up to 0.4 MPa on a 1/8 in branch feeding those cylinders, with the bar gauge letting an operator read the setting at a glance.
Benchtop analysers, sample-purge lines and small pneumatic actuators in lab equipment need modest, steady air at low pressure. A size 200 regulator with 1/8 in NPT ports fits tight panels, and the -20 to 70 C range covers unheated rooms and cold stores.
Textile machinery uses low-pressure air for thread tensioning, blowing and small actuator circuits. This GR200 low-pressure regulator on a 1/8 in drop from the main header keeps those circuits below 0.4 MPa independently of the main plant pressure.
Start with the port step: size 200 with 1/8 in NPT ports suits compact lines and low-flow branches - step up to GR300/400/600 for larger ports when the circuit demands more air. This is the L (low-pressure) type, regulating up to 0.4 MPa; if your setpoint sits above that, choose the standard GR type instead. The C3 code gives an external round gauge reading in bar; square embedded gauges and MPa or psi scales are the other catalogue choices. Thread is NPT here - PT is the standard and G (BSPP) is also orderable. The J code omits the bracket; add one if you want panel or surface mounting.
One honest note before you order: AirTAC publishes regulator flow as curves, not a single rated figure, so we cannot quote a flow number here. Send us your application details and we will confirm sizing against the datasheet curves before you commit.
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 number, so we do not state a flow figure for this unit. Tell us your inlet pressure, setpoint and expected air demand, and we will confirm the sizing against the datasheet curves on request before you order.
The C3 code in GR20006LJC3T specifies an external round gauge reading in bar; the alternative is an embedded square gauge with MPa, psi or bar scales. The J code means no mounting bracket is supplied, though GR regulators are also panel-mountable - order a bracket variant if you need one.
