The AirTAC GR20008LJF2T 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 GR20008LJF2T is an AirTAC GR-series air pressure regulator: it does one job only, holding a stable downstream pressure from a compressed-air supply. This is the low-pressure type, so its adjustment range tops out at 0.4 MPa, and the code decodes to a GR200 size unit with a 1/4 in NPT port, an embedded square gauge scaled in psi, no mounting bracket, and no reverse/check valve. There is no filter element, bowl or drain in this unit - it is regulation only, so it should sit downstream of filtration if the supply carries water or particles.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in standard and low-pressure types, with or without a gauge and bracket, and with PT (standard), G or NPT threads to order. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.
| GR200 | G-series pressure regulator, 200 body — sets the port range. |
|---|---|
| 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). |
| F | Gauge shape: Square. 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.

Set a gentle, repeatable holding pressure on pneumatic clamps and fixtures where the workpiece cannot take full line pressure - the low-pressure type keeps adjustment within a 0.4 MPa ceiling.
Feed spray guns and coating heads on a finishing line with a steady, reduced pressure so atomisation stays consistent from the first part of a shift to the last.
Regulate the supply to air knives and blow-off nozzles on a packaging or conveying line, trimming pressure down to what the cleaning job actually needs.
Start with the port step: this unit is size GR200 with a 1/4 in NPT port; larger GR sizes (300/400/600) carry larger ports and correspondingly greater flow capacity, so step up if your line needs more air. Because this is the L (low-pressure) type, choose it only where the working pressure stays at or below 0.4 MPa; the standard GR type covers the full 0.05-0.9 MPa range. The trailing T in the code specifies an NPT thread; PT is the catalogue standard and G (BSPP) is also available to order. Gauge options are the embedded square gauge fitted here (psi scale) or an external round gauge with MPa, psi or bar scales; the bracket is omitted on this configuration (J), and GR units are also panel-mountable. Flow is published as curves, not a single rating, 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 number, so there is no one l/min or SCFM figure we can honestly quote. Tell us your line pressure, set pressure and expected air demand and we will confirm the sizing from the datasheet on request before you order.
The L in the code marks the low-pressure type, whose adjustment range tops out at 0.4 MPa. If your process needs up to the full 0.9 MPa, choose the standard GR type instead - same sizes and ports, wider range. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C.
