The AirTAC GR20006LJNT 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, ordered without a 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 GR20006LJNT is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream air pressure from a variable upstream supply. This is the low-pressure (L) version, so its setting range tops out at 0.4 MPa, and the trailing T in the code specifies NPT1/8 (1/8 in NPT) ports. The N in the code means no pressure gauge is fitted, and J means no mounting bracket is supplied; as a GR unit it can also be panel-mounted. There is no filter, no bowl and no drain on this family - it is regulation only.
This is a genuine AirTAC part from the GR200 size, the smallest step in the GR range, which runs from 200 through 600 with increasing port sizes and flow capacity. Options across the series include a fitted gauge (embedded square or external round, with MPa, psi or bar scales), a reverse/check valve, a bracket, and PT, G or NPT threads. Flow for this regulator 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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 lines that use gentle pneumatic clamping or hold-down of film and cartons need a stable, low set pressure. This low-pressure GR200 regulator holds that setting steady at the machine, with 1/8 in NPT ports suiting compact valve and cylinder circuits.
Bench-scale spray, coating and laboratory air setups often run at deliberately low pressures where a full-range regulator has too much headroom. The 0.4 MPa ceiling of this L-type GR200 gives fine control in that band, feeding nozzles or applicators from a 1/8 in NPT takeoff.
Textile machines and light assembly stations use small air cylinders for sorting, lifting and pressing at modest pressures. A GR200 low-pressure regulator mounted at the machine keeps those actuators consistent, and its panel-mount capability lets it sit neatly in the machine's control cabinet or frame.
Start with the port and flow step: 200-series GR regulators carry 1/8 in ports, and larger sizes (300/400/600) step up in port and flow capacity, so size the unit against the air your circuit actually consumes. If your working pressure never exceeds 0.4 MPa, the low-pressure L type like this one is the right pick; for higher settings, choose the standard GR type with its 0.05-0.9 MPa range. Decide whether you want a gauge fitted (square embedded or round external, in MPa, psi or bar scale), whether you need the reverse/check valve option, and whether a mounting bracket is required - this code ships without one. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order, as specified here. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing 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 GR flow as characteristic curves rather than a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Tell us your application - supply pressure, set pressure and the air your equipment consumes - and we will confirm the datasheet curve and check the sizing for you before you order.
The N in GR20006LJNT means the regulator ships without a pressure gauge, and J means without a mounting bracket. GR regulators can be ordered with an embedded square gauge or an external round gauge, in MPa, psi or bar scale, with or without a bracket. If you need a gauge on this unit, ask us for the equivalent code with the gauge position filled.
