The AirTAC GR20006LJF3TK 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 AirTAC GR20006LJF3TK is a pressure regulator and nothing else: it reduces and holds downstream air pressure, with no filtration and no lubrication in its function. This configuration is the GR200 size with a 1/8 in NPT port, built as the low-pressure type with an adjustment range up to 0.4 MPa for circuits that must not see full line pressure. It carries an embedded square gauge reading in bar, a reverse/check valve fitted, and no mounting bracket, so it is suited to panel or direct mounting in the equipment.
This is a genuine AirTAC part. The GR series spans sizes 200 to 600 with port sizes from 1/8 in to 1 in, standard or low-pressure regulation, gauge scales in MPa, psi or bar, an optional reverse/check valve, and PT, G or NPT threads as order options. Flow is published as curves rather than a single rating, so ask us to confirm the figures for your application.

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). |
| F | Gauge shape: Square. 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. |
| 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.

On a paint or coating line, the gun's atomizing air must sit well below main line pressure. This low-pressure GR regulator, set up to 0.4 MPa with its bar-scale gauge, lets the operator dial in and hold the gentle setting the finish needs.
A leak or proof-pressure test station runs parts at a controlled low pressure. The GR20006LJF3TK regulates the test air down from shop supply, the check valve holds the setting against backflow, and the 1/8 in NPT port suits compact bench plumbing.
Heat-seal or labeling heads on a packaging machine need soft, steady actuation air so films and cartons are not crushed. This regulator supplies that low-pressure circuit from the main drop, with the gauge giving the line operator a direct bar reading.
Start with the size and port: GR200 is the smallest step in the GR range and takes a 1/8 in port here, so match it to the line size and the air demand of the circuit. Choose the low-pressure (L) type when the downstream setting must stay at or below 0.4 MPa; the standard type covers the wider range. This unit has the square gauge with a bar scale (F3) and the reverse/check valve (K) already selected, and no bracket (J), which suits panel mounting. Thread is NPT here; PT is the standard option and G is also available to order. Because GR flow is published as curves rather than a single rating, send us your application details and we will confirm sizing 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 GR regulator flow as performance curves rather than a single rated figure, so we do not quote a number. Tell us your line pressure, set pressure and air demand, and we will confirm the flow from the datasheet for your application on request.
L marks the low-pressure type of the GR series. Its adjustment range goes up to 0.4 MPa instead of the standard type's wider range, which suits circuits that must run gently. This unit also carries a square bar-scale gauge (F3) and a reverse/check valve (K), with no bracket (J), and is offered in PT, G or NPT threads to order.
