The AirTAC GR20006LF2T 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 GR20006LF2T is a pressure regulator only: it reduces and holds downstream air pressure, with no filter element, no drain bowl and no lubricator. This configuration is the low-pressure (L) type, so its adjustment range tops out at 0.4 MPa, and it is built in size 200 with an NPT1/8 (1/8 in) port. A square pressure gauge in psi scale is fitted as standard, and the mounting bracket is included; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR regulator family spans sizes 200 to 600, with port sizes stepping up from 1/8 in to 1 in, thread options PT (standard), G (BSPP) and NPT, standard or low-pressure regulation, gauge scale choices of MPa, psi or bar, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. |
| (blank) | Fixing bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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 fixture-clamping circuit where delicate workpieces are held at reduced pressure, the GR20006LF2T sets and holds the downstream pressure within its 0.4 MPa low-pressure range, with the psi gauge giving the operator a direct readout at the clamp panel.
On a leak-test or proof-pressure bench that runs test articles at low pressures, this regulator gives the operator fine adjustment up to 0.4 MPa on the test line, with the 1/8 in NPT port suiting compact bench manifolds and the included bracket fixing the unit beside the gauges.
On packaging machinery where sealing bars or forming tools are actuated at reduced pressure to avoid crushing film, the low-pressure type regulator holds that section's supply steady, while the rest of the machine runs at full line pressure upstream.
Start with the port and size step: size 200 with a 1/8 in port suits the smallest branch lines, and larger sizes 300/400/600 carry bigger ports for higher-demand circuits - match the step to the flow your line needs. This unit is the low-pressure type, correct where the working pressure must stay at or below 0.4 MPa; for circuits running up to 0.9 MPa choose the standard GR type instead. The fitted square gauge reads in psi; MPa or bar scales are available if your panel standardises differently.
Thread is NPT here, but PT is the catalogue standard and G (BSPP) is also an option - pick to match your fittings. A bracket is included and the GR can also be panel-mounted. Because flow is published as curves and not a single rating, 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 regulator flow as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs and we will confirm the sizing against the datasheet on request before you order.
The L in the code marks the low-pressure regulator type: its adjustment range tops out at 0.4 MPa instead of the standard type's higher range. Choose it for circuits that must never see more than 0.4 MPa; for general supply lines up to 0.9 MPa, order the standard GR type instead. Max inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -20 to 70 C.
