The AirTAC GR20008LC2G AirTAC Air Pressure Regulator G1/4, Low-Pressure 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 GR20008LC2G is an AirTAC GR200 series air pressure regulator, built to do one job: hold a steady downstream air pressure from a compressed-air supply. This configuration is the low-pressure type, so the setting range tops out at 0.4 MPa, and it carries a 1/4 in port with G (BSPP) thread. A round external gauge scaled in psi is fitted so the set pressure can be read directly at the unit, and the mounting bracket is included; the GR200 can also be panel-mounted.
This is a genuine AirTAC part. The GR line spans four body sizes (200, 300, 400 and 600) with ports from 1/8 in to 1 in, in standard or low-pressure versions, with round or square gauges in MPa, psi or bar scales, an optional reverse/check valve, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C, wider than the rest of the G family. Flow is published as curves rather than a single rating, so ask us to confirm the figures against your application.

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.

Carton-closing and tray-forming machines often need their pneumatic clamps held well below normal line pressure. A low-pressure GR200 regulator at each clamp station lets the setter dial in a safe holding pressure that cannot be overrun, with the psi gauge readable right at the station.
Air knives that sweep water or crumbs off product before filling run best at gentle, stable pressures. A GR20008 low-pressure regulator on the 1/4 in feed to each knife keeps the blow-off pressure fixed, so the line dries consistently without disturbing lightweight product.
Spray nozzles and atomizers in coating and test booths are sensitive to supply pressure drift. Feeding the nozzle manifold through this low-pressure GR200 regulator holds the atomizing air steady, and the round psi gauge lets the operator verify the set point before each run.
Start with the port step: the 200 size takes 1/4 in ports, and larger sizes (300/400/600) move up through 3/8 in to 1 in as your flow demand grows. Then pick the regulator type: this low-pressure (L) version is for circuits that must never be set above 0.4 MPa; the standard GR covers settings up to 0.9 MPa. Choose the gauge scale you want to read - MPa, psi or bar - and the gauge style (this unit has the external round gauge in psi). Thread is G (BSPP) here; PT is the catalogue standard and NPT is also an order option. A bracket is included, and the GR200 is panel-mountable as well.
One honest note on sizing: AirTAC publishes regulator flow as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application and we will confirm the sizing from 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 datasheet, not as a single rated number, so we do not state a flow figure here. Tell us your line pressure, set pressure and the air demand of your equipment, and we will confirm the sizing from the datasheet before you order.
The L in the code marks the low-pressure type, whose setting range tops out at 0.4 MPa - useful where downstream equipment must not see high pressure. If your circuit needs settings up to 0.9 MPa, order the standard GR200 version instead; the same 200 size, 1/4 in port and gauge options are available on it.
