The AirTAC GR20006LJNTK 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 GR20006LJNTK is an AirTAC GR-series pressure regulator for compressed air: it controls downstream pressure and nothing else - there is no filter element, no drain bowl and no lubricator in this family. This configuration is the 200 size with a 1/8 in NPT port, built as the low-pressure type with a regulation range up to 0.4 MPa, so it suits circuits that must never see full line pressure. A reverse/check valve is fitted, which holds the set downstream pressure if the upstream supply is interrupted. No pressure gauge is included with this code, and no mounting bracket is supplied; the GR series is also panel-mountable.
This is a genuine AirTAC part from the GR family, which spans the 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, standard or low-pressure regulation, gauge and bracket options, and PT, G or NPT threads. We do not publish a single rated flow figure for this unit - flow is given as curves in the AirTAC catalogue - so ask us and we will confirm the datasheet figures against your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. |
| 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. |
| 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.

Set a gentle, stable supply pressure to air-assisted spray guns and coating applicators on a finishing line, where the process calls for a low regulated pressure well below full shop-air level.
Feed positioners and pilot stages of pneumatic control valves on a process skid, where actuator manufacturers specify a low supply pressure and the check valve holds the pilot line if the header drops.
Provide a controlled low-pressure air supply to laboratory and workshop test fixtures - leak-test stations, small pneumatic jigs and calibration benches - where the circuit must not exceed a low setpoint.
Start with the port step: the 200 size takes a 1/8 in port here, and larger sizes (300/400/600) step up in port and flow capacity, so match the size to the air demand of the circuit. This code is the low-pressure type (L), regulating up to 0.4 MPa - choose the standard GR type instead if you need the full 0.05-0.9 MPa range. The fitted reverse/check valve (K) is the right choice where downstream pressure must be held on supply loss. Thread is NPT on this unit; PT is the standard option and G (BSPP) is also available to order. No gauge is fitted with this code - gauge options with MPa, psi or bar scales exist on other codes if you want a visual setpoint. Flow for this series is published as curves rather than a single rating, so send us your application details and we will confirm sizing from 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 flow for the GR series as curves in the catalogue, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the relevant flow data from the datasheet before you order.
The N in the code means no pressure gauge is supplied with this unit; gauge options with MPa, psi or bar scales are available on other codes. The L marks the low-pressure regulator type, which regulates up to 0.4 MPa, and the K means a reverse/check valve is fitted so downstream pressure is held if the supply is lost.
