The AirTAC GR20008LJC2 AirTAC Low-Pressure Air Regulator PT1/4 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.
GR20008LJC2 is an AirTAC GR series air pressure regulator: its only job is to reduce and hold downstream pressure on a compressed-air supply - no filtering, no bowl, no lubrication. It is the size 200 unit with a PT1/4 taper port, in the low-pressure L type with a set pressure up to 0.4 MPa. The J configuration comes without a mounting bracket, and C2 specifies an external round pressure gauge scaled in psi.
This is a genuine AirTAC part. The GR family is rated for compressed air up to 1.0 MPa (145 psi) inlet and -20 to 70 C, and is offered in sizes 200, 300, 400 and 600 with progressively larger ports and more flow. Across the family you can order brackets, square or round gauges in MPa, psi or bar, the reverse (check) valve option, and G (BSPP) or NPT threads as alternatives to standard PT. Flow figures are published only as curves, so ask us to confirm sizing and the datasheet 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.

| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

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

| (blank) | No reverse-flow valve (the default). |
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.

Trim the supply pressure to low-torque air screwdrivers and small air ratchets at a manual assembly bench, protecting light-duty fasteners.
Regulate a gentle blast of air that clears dust and debris from product surfaces as items travel along a packaging conveyor.
Feed reduced, closely controlled air to a workshop test rig used to check low-pressure pneumatic circuits on truck and trailer components.
Start with size and port: this 200 unit has a PT1/4 port; 300/400/600 give larger ports and more capacity, matched against the flow curves. Choose between the low-pressure L type fitted here (sets up to 0.4 MPa) and the standard GR range of 0.05-0.9 MPa (7-130 psi). Pick your gauge scale - this code's round gauge reads in psi, with MPa and bar scales and a square-gauge option available. Thread is PT as standard, with G and NPT as ordered options, and J means no bracket is fitted. Because flow is published as curves rather than a single rating, ask us to check 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.
No single rated figure exists in the catalogue - AirTAC publishes GR performance as flow curves. Share your inlet pressure, set pressure and required flow, and we will confirm sizing from the datasheet curves on request.
No. There is no K in this code, so no reverse valve is fitted, and downstream air cannot vent back through the regulator when supply is removed. If you need that vent-back function, order the K version of the same size.
