The AirTAC GR20006LNT 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 GR20006LNT is an AirTAC GR-series air pressure regulator in the compact 200 size, fitted with a 1/8 in NPT port. This is the low-pressure (L) type, so its adjustment range goes up to 0.4 MPa, making it suitable for circuits that must never see full line pressure. It is supplied without a gauge (code N) and without a reverse/check valve, and it includes a mounting bracket; the GR body is also panel-mountable. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the GR series carries the widest temperature window in the G family at -20 to 70 C.
This is a genuine AirTAC part. The GR family is offered in sizes 200, 300, 400 and 600 with progressively larger ports and flow capacity; options include standard or low-pressure regulation, an embedded square gauge or external round gauge with MPa, psi or bar scale, G (BSPP) or NPT thread variants, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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. |
| (blank) | Fixing bracket included. |
| 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.

On a bench that leak-tests or function-checks small pneumatic components, the low-pressure setting range keeps test-piece supply air held at a controlled value below 0.4 MPa, with the 1/8 in NPT port matching compact bench plumbing.
Feeding an airbrush or spray gun from a shop-air drop, this regulator lets the operator set a gentle, repeatable supply pressure for atomising air, protecting the finish from pressure swings on the main line.
On a light-duty gripper or small-bore cylinder station, the GR20006LNT holds the actuation pressure at a fixed low setting so delicate parts are handled without over-force, with the included bracket mounting the unit beside the valve manifold.
Start with the port and flow path: the 200 size with a 1/8 in port is the smallest GR step, so match it to the line size and required air demand of the circuit, stepping up to 300, 400 or 600 where demand is higher. Because this is the low-pressure (L) type, choose it only where the downstream setting must stay at or below 0.4 MPa; for settings up to 0.9 MPa, use the standard GR type instead. Decide whether you need a gauge (square embedded or external round, in MPa, psi or bar scale) - this model ships without one, so add a separate gauge if a visual setting is required. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also orderable. A bracket is included, and the GR can also be panel-mounted.
One honest note before ordering: AirTAC publishes GR flow capacity as curves, not as a single rated number, so we do not quote a flow figure here. Ask us to confirm the flow curve and sizing against your application 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 GR-series flow capacity as performance curves, not as a single rated figure, so we do not quote a flow number for this model. Contact us and we will confirm the flow curve from the datasheet and check it against your application before you order.
The L marks the low-pressure type: its adjustment range goes up to 0.4 MPa instead of the standard GR range, so use it only where downstream settings must stay low. The N in the code means no gauge is supplied - if operators need to read or dial in the setting, add a gauge (square embedded or external round, with MPa, psi or bar scale) when specifying.
