The AirTAC GR200-08LJC2T AirTAC Low-Pressure Regulator NPT1/4 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.
The GR200-08LJC2T 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 is the low-pressure type, adjusted up to 0.4 MPa, with a 1/4 in NPT port, a round pressure gauge reading in psi, and no mounting bracket fitted. As a regulator it contains no filter element and no bowl, so it neither removes water or particulate nor adds lubrication - pair it with a filter or F.R.L. units if the line needs those.
This is a genuine AirTAC part in the GR200 size family, which spans sizes 200 through 600 with port options from 1/8 in to 1 in and PT, G or NPT threads. GR units are also panel-mountable, and gauge scale and bracket options can be selected per code. Because flow is published as curves rather than a single rating, we confirm the datasheet and sizing 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.

|---|---|
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (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.

Sets and holds a gentle, stable supply pressure to glue pumps or coating heads on a packaging or converting line, where the process calls for settings well below standard regulator range and a psi readout at the panel.
Feeds positioners and pilot actuators on process valves in a plant skid, keeping the control signal pressure steady at low setpoints with a 1/4 in NPT hook-up that suits instrument take-offs.
Drops shop air to a safe, repeatable low pressure at a laboratory bench or test rig, protecting glassware, sample fixtures and sensitive pneumatics from supply swings, with the round psi gauge giving a clear local reading.
Start with the port step: this unit is 1/4 in NPT, so match it to your line size and the flow the application needs - larger GR sizes (300/400/600) carry bigger ports and more flow, and we will confirm curve figures against your demand before you order. The L code here is the low-pressure type, adjusted up to 0.4 MPa; if your circuit needs settings above that, choose a standard GR instead, which adjusts 0.05-0.9 MPa. The C2 code gives an external round gauge scaled in psi; square embedded gauges and MPa or bar scales are the other gauge choices. Thread is NPT as ordered, with PT (standard) and G available as catalogue options, and J means no bracket is supplied - add the bracket code if you want one. Ask us to confirm sizing against the 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 regulator flow as performance curves, not as a single rated number, so we do not quote a figure here. Send us your upstream pressure, set pressure and expected air demand, and we will confirm the curve data and correct size from the datasheet on request before you order.
L marks the low-pressure type: its adjustment range tops out at 0.4 MPa, versus 0.05-0.9 MPa for the standard GR. Everything else in this code decodes as 1/4 in NPT port, round gauge scaled in psi, no mounting bracket, and no reverse/check valve fitted.
