The AirTAC GR200-08LF2T AirTAC Air 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 AirTAC GR200-08LF2T is a low-pressure air pressure regulator from the GR200 series, sized for a 1/4 in NPT port. It does one job only: holding a steady downstream pressure, in this case anywhere up to 0.4 MPa, on compressed-air lines where a low setting is needed. The embedded square gauge is fitted with a psi scale, a mounting bracket is included, and the regulator is also panel-mountable. It handles a maximum inlet pressure of 1.0 MPa (145 psi) and works from -20 to 70 C, a wider temperature window than the rest of the G-series treatment units.
This is a genuine AirTAC part. The GR series is available in sizes 200, 300, 400 and 600 with a step of port sizes, in standard or low-pressure (L) types, with or without a gauge, with MPa, psi or bar gauge scales, and in PT (standard), G or NPT threads. We do not quote a single rated flow figure because AirTAC publishes flow as curves; ask us and we will confirm the datasheet figures for your application on request.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.

Fixture clamps that must close at a deliberately low, repeatable pressure take their setting from a low-pressure regulator. This unit sits in the 1/4 in line to the clamp cylinders, holding the set pressure while the weld cell cycles.
Spray and atomising air on a finishing line is run at a low, stable setting. This regulator is placed on the 1/4 in branch feeding the spray station, with the psi-scaled square gauge letting operators read and hold the set point.
Packaging machines often use low-pressure pilot air to shift soft valves and actuators gently. This low-pressure regulator trims that pilot circuit down from the main supply, keeping the setting steady through the machine's cycle.
Start with the port step: this unit is the 200 size with a 1/4 in NPT port; larger GR sizes (300/400/600) carry larger ports for larger air demand, so match the size to the line rather than upsizing blindly. Because this is the L type, its regulation range tops out at 0.4 MPa - if your circuit needs settings above that, choose a standard GR instead. The fitted square gauge reads in psi; MPa and bar scales are available if you prefer. Thread choice is PT as the standard, with G (BSPP) and NPT as order options - this code carries NPT. A mounting bracket is included, and GR is also panel-mountable.
One honest note on sizing: AirTAC publishes regulator flow as curves, not as a single rated number, so we cannot quote a rated flow here. Send us your application details and we will confirm the sizing against the datasheet curves 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 rated flow number for this unit. Tell us your line size and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The L in the code marks the low-pressure regulator type: its adjustment range goes up to 0.4 MPa instead of the standard GR range. Choose this type when your circuit settings stay low; if you need settings above 0.4 MPa, the standard GR type is the right pick. Everything else - the 1/4 in NPT port, fitted square psi gauge, included bracket and -20 to 70 C operating range - stays as decoded from this code.
