The AirTAC AirTAC GR20008LC2 Regulator PT1/4, psi Round Gauge 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 GR20008LC2 is a compressed-air pressure regulator from the G series, sized 200 with 1/4 in. PT ports. It is the low-pressure (L) type, so its output is adjustable up to 0.4 MPa for circuits that must not run at full line pressure. It carries a round external pressure gauge with a psi scale, includes a mounting bracket, and is rated to 1.0 MPa (145 psi) maximum inlet pressure with an operating temperature of -20 to 70 C.
This is a genuine AirTAC part. The GR series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in., a choice of gauge (round or square; MPa, psi or bar scale), a low-pressure option, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm datasheet figures on request 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.

| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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.

Set a reduced, stable supply to pneumatic clamps and swing cylinders on a machining cell so workholding pressure stays below the main line setting.
Feed air cushion tables and light-duty pneumatically actuated presses where the circuit is specified to run at low regulated pressure only.
Regulate air to carton-sealer and case-packer cylinders on a packaging conveyor line, with the psi-scale round gauge giving operators a direct set-point readout.
This code fixes the key choices: size 200 with 1/4 in. PT ports, low-pressure (L) type with adjustment up to 0.4 MPa, and a round gauge on a psi scale. If your line needs higher set points, the standard GR type adjusts 0.05-0.9 MPa; if you prefer MPa or bar readout or a square gauge, those are separate order codes. PT thread is the standard; G (BSPP) and NPT are catalogue options, and a no-bracket (J) version exists.
For sizing, work from the port step: 200/1/4 in. suits light branch lines, while larger sizes carry more flow. Flow for this series is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
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 GR series flow as curves rather than a single rated number, so there is no one figure we can quote. Tell us your inlet pressure and required downstream flow and we will confirm the sizing from the datasheet curves on request.
The L type limits the regulated output to up to 0.4 MPa, for circuits designed around low set points. The standard GR adjusts 0.05-0.9 MPa. Gauge style and scale are also order choices: this code has a round psi gauge, while square gauges and MPa or bar scales are separate codes.
