The AirTAC GR20006LF1T AirTAC Air 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 GR20006LF1T is an AirTAC GR200 air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply, and it does nothing else - no filter element, no drain bowl and no lubricator are part of this family. This configuration is the low-pressure type, so it adjusts downstream pressure up to 0.4 MPa, and it is built in the compact size 200 body with a 1/8 in NPT port. A square pressure gauge scaled in MPa is embedded as standard, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) across a working temperature range of -20 to 70 C - wider than the rest of the G series.
This is a genuine AirTAC part. The GR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in standard or low-pressure types, with PT as the standard thread and G (BSPP) or NPT as order options, and with or without a gauge or mounting bracket. Flow is published by AirTAC as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures 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.

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 lab bench or QC station running pneumatic tests at low set pressures, the GR20006LF1T trims the supply down to the 0.4 MPa ceiling the low-pressure type covers, with the MPa gauge giving the operator a direct pressure readout at the point of use.
Compact pick-and-place cells with 1/8 in air lines often run grippers and small cylinders at deliberately low pressures to protect delicate parts. This low-pressure regulator drops the branch line to a gentle setting while the main line stays at full pressure.
Directional-valve pilot ports and low-pressure actuation branches on packaging and material-handling machines need a steady, reduced feed independent of the main header. A size 200 regulator with an embedded gauge set into the branch keeps the pilot circuit stable as header pressure swings.
Start with the port step: size 200 with a 1/8 in NPT port suits small pneumatic circuits, and the larger GR sizes (300/400/600) step up in port and flow capacity. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering. Then set the regulator type: this unit is the low-pressure L type, adjusting up to 0.4 MPa - if your circuit needs the full 0.05-0.9 MPa range, the standard GR type is the right choice instead. For the gauge, the embedded square gauge scaled in MPa is fitted here; psi or bar scales and an external round gauge are the other options. Thread is NPT on this code, with PT as the standard and G (BSPP) as an order option. A mounting bracket is included, and GR is also panel-mountable.
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 number, so we do not quote a flow figure here. Tell us your application and we will confirm the flow and sizing details from the datasheet on request before you order.
The L marks the low-pressure regulator type: its adjustment range goes up to 0.4 MPa instead of the standard GR range of 0.05-0.9 MPa. Choose this code for circuits that must never exceed 0.4 MPa; choose the standard type when you need the full range. Everything else - size 200, 1/8 in NPT port, embedded square MPa gauge, included bracket - is decoded from the rest of the code.
