The AirTAC GR20006LJC2K AirTAC Low-Pressure Regulator, PT1/8 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 GR20006LJC2K is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady as upstream supply and air demand fluctuate. This unit is the size 200 frame with a PT1/8 (1/8 in) port, built as the low-pressure type, so its adjustment range tops out at 0.4 MPa for circuits that must never see full line pressure. It arrives configured with an external round gauge scaled in psi, a built-in reverse (check) valve so downstream pressure is held if the supply side drops, and no mounting bracket - the GR body is also panel-mountable. Maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, in standard or low-pressure types, with your choice of gauge style and scale, PT, G or NPT threads, and optional reverse 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 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 carton-sealing or wrapping machine where the pneumatic clamp or hold-down cylinders must see only a gentle, stable pressure, this low-pressure regulator sets and holds the reduced line while the psi gauge gives the operator a direct readout.
For a lab bench or test rig running air-operated instruments and small actuators, the regulator holds a steady reduced pressure from the house supply, and the built-in check valve keeps the circuit from dumping back if the main air is shut off mid-test.
On a machining centre where fixture clamps and part sensors are piloted at a reduced pressure independent of the main actuator line, this size 200 regulator on the 1/8 in pilot branch keeps the pilot circuit stable and protected from full header pressure.
Start with the port step: size 200 with a PT1/8 port suits the smallest branch lines, while sizes 300, 400 and 600 step up in port and flow capacity - match the frame to your line size and required flow. This unit is the low-pressure (L) type with adjustment up to 0.4 MPa; if your circuit needs to set higher than that, choose the standard GR type instead, which adjusts from 0.05 to 0.9 MPa. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT available to order as specifications. The K code adds a reverse (check) valve - leave it off if you do not need downstream pressure held on supply loss - and the J code means no bracket, though the GR is panel-mountable either way. One honest note on sizing: flow is published as curves, not a single rating, so ask us to confirm the datasheet figures against your application before ordering.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes regulator flow as curves rather than a single rated figure, so there is no one rated flow number we can quote. Tell us your line size and application and we will confirm the datasheet flow figures for this unit on request before you order.
The L code in GR20006LJC2K makes it a low-pressure type: its adjustment range tops out at 0.4 MPa, which suits circuits that must never be set near full line pressure. The standard GR type adjusts from 0.05 to 0.9 MPa, so if you need to set higher than 0.4 MPa, order the standard version instead. Maximum inlet pressure is 1.0 MPa (145 psi) either way.
