The AirTAC GR20008LF1T AirTAC Low-Pressure Regulator NPT1/4 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 PT1/4" 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 GR20008LF1T is an AirTAC GR200 series air pressure regulator for compressed air, built for lines that must hold a setpoint at or below 0.4 MPa. The L in the code marks the low-pressure type, so this unit is intended for circuits whose working pressure sits below the standard regulator range rather than for full 0.9 MPa service. It is the 200 size with 1/4 in NPT ports, carries a maximum inlet pressure of 1.0 MPa (145 psi), and operates from -20 to 70 C - the widest temperature window in the G family. A square pressure gauge scaled in MPa is included as standard, and the trailing T specifies NPT threading.
This is a genuine AirTAC part. The GR series spans the 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 in, and can be ordered with PT or G (BSPP) threads, psi or bar gauge scales, a reverse/check valve, or no gauge. GR units are bracket-mountable as supplied and also panel-mountable. 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.

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.

Bagging and carton-sealing machines often run actuator circuits at gentle pressures to avoid crushing product. This low-pressure regulator holds the setpoint on the 1/4 in drop to the machine's valve manifold.
A workholding fixture on a CNC cell that clamps delicate parts needs a controlled, moderate pressure. The GR20008LF1T regulates the clamp circuit downstream of the shop main, with the MPa gauge giving the operator a clear setpoint readout.
Bench-top test rigs and lab apparatus fed from a compressed-air drop frequently need a stable low-pressure supply. The -20 to 70 C operating window and 1/4 in NPT ports make this regulator a straightforward fit on the bench supply.
Start with the port step: the 200 size takes 1/4 in ports here, and larger sizes (300/400/600) step up to 1/2, 3/4 and 1 in as your line's flow demand grows. This unit is the L low-pressure type, so choose it when the controlled pressure must stay at or below 0.4 MPa; for settings up to 0.9 MPa, the standard GR type is the correct pick. The F1 gauge code gives the embedded square gauge scaled in MPa - order the alternative scale if your crew works in psi or bar. Thread is NPT on this code; PT is the catalogue standard and G (BSPP) is available to order. A mounting bracket is included, and GR also panel-mounts. Because flow is published as curves rather than one rated number, ask us to confirm sizing against your application before ordering.
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 performance curves rather than a single rated figure, so we do not quote one number here. Tell us your inlet pressure, setpoint and the equipment you are feeding, and we will confirm the sizing from the datasheet on request.
L marks the low-pressure type of the GR regulator, with an adjustment range up to 0.4 MPa. Choose it when your process setpoint sits in that lower band; for controlled pressures up to 0.9 MPa, order the standard GR type instead.
