The AirTAC GR20008LC2T 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 GR20008LC2T is an AirTAC GR200 air pressure regulator built for low-pressure duty, with a 1/4 in NPT port and an external round gauge scaled in psi. It does one job only: holding a steady downstream air pressure. The L in the code marks the low-pressure type, so the setting range goes up to 0.4 MPa, while the unit itself accepts up to 1.0 MPa (145 psi) at the inlet. There is no filter, no bowl and no drain on this model - it is regulation only, so pair it upstream with a filter if the air needs cleaning. It works in compressed air from -20 to 70 C, the widest temperature window in the G family, and a mounting bracket is included; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR line runs in four sizes (200/300/400/600) with ports from 1/8 to 1 in, and each size can be ordered as standard or low-pressure type, with or without a gauge, with MPa, psi or bar gauge scales, with PT, G or NPT threads, and with an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application before you order.

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 carton sealing or wrapping line, heat-seal arms and hold-down clamps often need a gentle, stable air pressure well below main-line pressure. This low-pressure GR200 regulator holds that reduced setting on a 1/4 in drop, with the psi gauge letting operators check the setpoint at a glance.
Pneumatic grippers on pick-and-place robots are sensitive to pressure swings - too high and parts get marked, too low and parts slip. Feeding the gripper circuit through this GR200 low-pressure regulator keeps the clamp force consistent, and the -20 to 70 C range covers cold-store and shop-floor conditions alike.
Bottle and carton conveyors use low-pressure air jets and hold-down pads to keep product stable through curves and transfers. This regulator takes the 1/4 in branch off the main header and sets the gentle pressure those jets need, with the round psi gauge giving line staff a visible, repeatable setting.
Size and port come first: the 200 size with a 1/4 in port suits lighter air demand, and the larger sizes (300/400/600) step up in port and flow capacity - match the step to your line's air use rather than guessing. This code carries the L low-pressure type, so choose it only where your setpoint stays within 0.4 MPa; for higher setpoints order the standard GR. The C2 suffix gives you a round external gauge on a psi scale - useful if your team reads psi, though MPa and bar scales are also available. Thread here is NPT (T); PT is the catalogue standard and G (BSPP) is the other option, so pick the one your pipework uses. A bracket is included, and the GR can also be panel-mounted. One honest note: AirTAC publishes flow as curves, not a single rated number, so 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 in the catalogue rather than a single rated figure, so we do not quote one number here. Tell us your line's air demand and inlet pressure and we will confirm the sizing from the datasheet on request before you order.
L marks the low-pressure type: its setting range goes up to 0.4 MPa instead of the standard GR range. The unit still accepts up to 1.0 MPa (145 psi) at the inlet. If your setpoint needs to go above 0.4 MPa, order the standard GR200 version instead - the suffix changes with it.
