The AirTAC GR20006LJF3T AirTAC Regulator NPT1/8 Low-Pressure Type 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 PT1/8" 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 GR20006LJF3T is an AirTAC GR200 series air pressure regulator for compressed air only. It is a low-pressure (L) type, so the outlet setting can be adjusted up to 0.4 MPa, and it carries a 1/8 in NPT port. 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-series families. An embedded square gauge with a bar scale is fitted as standard, and the J suffix means no mounting bracket is supplied, though the GR body is also panel-mountable. As a pure regulator it contains no filter, no bowl and no drain, and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with ports from 1/8 in to 1 in, standard and low-pressure types, gauge scales in MPa, psi or bar, an optional reverse/check valve, and G, NPT or PT threads. Flow for GR regulators is published as curves rather than a single rated figure, so ask us to 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.

|---|---|
| 06 | Port size PT1/8". 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. |

| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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.

On a carton-sealing or bagging line, cylinder and pilot circuits often need a gentle, stable supply pressure well below the main header level. This low-pressure GR200 regulator with a 1/8 in NPT port and bar-scale gauge lets an operator set and read a low downstream pressure directly at the machine.
A laboratory or QA test bench drawing air through small tubing benefits from a compact 1/8 in regulator. The low-pressure type keeps the test article within a 0.4 MPa ceiling, and the embedded square gauge in bar gives a clear local reading without a separate instrument.
Positioners, solenoid pilots and small pneumatic control valves on a process skid typically need a reduced, steady supply rather than full header pressure. This GR200 low-pressure regulator, panel-mountable and fitted with a bar gauge, provides that reduced setting at the point of use.
Start with the port step: the GR200 size covers the smaller ports, and this unit is the 1/8 in (06) version in NPT thread; PT is the standard thread and G (BSPP) or NPT are catalogue options to order, so match the thread to your piping. Choose the low-pressure (L) type only when your downstream setting must stay at or below 0.4 MPa; for settings up to 0.9 MPa use the standard GR type. The square gauge fitted here reads in bar; MPa and psi scales are available as alternatives. Bracket (J = none) and the K reverse/check valve are the remaining decodable choices. Because regulator flow is published as curves rather than a single rating, 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 regulator flow as performance curves rather than a single rated figure, so no single flow number, Cv or SCFM value is quoted here. Tell us your application and we will confirm the flow and sizing figures from the datasheet on request before you order.
The L in the code marks the low-pressure regulator type, whose outlet setting range goes up to 0.4 MPa instead of the standard type's higher range. The F3 means a square gauge is fitted with a bar scale; MPa (1) and psi (2) scales are the other catalogue options.
