The AirTAC GR20006LC2G AirTAC Low-Pressure Regulator, G1/8 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 GR20006LC2G is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream pressure from your compressed-air supply. This unit is the low-pressure type, so its setting range tops out at 0.4 MPa, and it is built in the compact 200 size with a G1/8 (1/8 in) female port. The trailing G in the code means the threaded connection is G (BSPP); PT is the catalogue standard and NPT is also available to order. A round pressure gauge with a psi scale is fitted so you can read and dial in the setpoint, and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), and the GR family carries the widest temperature window in the G series at -20 to 70 C.
This is a genuine AirTAC part. The GR line runs from size 200 up to 600, with larger port sizes for higher flow demand, a choice of gauge scale (MPa, psi or bar), standard or low-pressure regulation, an optional reverse/check valve, and PT, G or NPT threads. Because AirTAC publishes regulator flow as curves rather than a single rated figure, we confirm the datasheet and flow-curve 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 paint or coating line, the gun circuit often needs a gentle, stable pressure well below main-line level. This low-pressure regulator lets an operator dial the setpoint in on the psi gauge and hold it steady through the shift.
Packaging and cartoning machines frequently run pilot valves and small actuators on a reduced-pressure branch off the main supply. A GR200 with a 1/8 in port drops that branch to the low pressure the pilot circuit expects.
A lab or QC bench testing small pneumatic components needs a controllable, repeatable supply pressure. This regulator, with its round psi gauge and included bracket, gives the bench a readable, adjustable low-pressure feed.
Start with the port step: the 200 size here takes a 1/8 in connection, and the GR series steps up through 300, 400 and 600 with larger ports. Match the size to the flow your line needs, then decide the regulation type: this low-pressure (L) version sets up to 0.4 MPa, while the standard GR covers 0.05-0.9 MPa, so pick L only where your process genuinely runs low. Choose the gauge scale to suit your operators - this unit ships with a round gauge in psi, and MPa or bar scales are alternatives. Thread is the other real choice: PT is the catalogue standard, with G (BSPP) and NPT as orderable options, and a mounting bracket is included (GR is also panel-mountable). One honest caveat: AirTAC publishes regulator flow as curves, not a single rated number, so ask us to confirm sizing against your application 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 there is no one flow number we can honestly quote. Tell us your line pressure, set pressure and expected air demand, and we will confirm the flow-curve figures from the datasheet for your application on request.
The L in the code marks the low-pressure type, whose setting range goes up to 0.4 MPa - right for spray, pilot and similar low-pressure circuits. If your process needs up to 0.9 MPa, choose the standard GR type instead; the same 200 size and G1/8 port are available in that version.
