The AirTAC GR20006LJF1T AirTAC Air Pressure Regulator NPT1/8 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 GR20006LJF1T is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply, and it contains no filter, no bowl and no lubricator. This unit is the low-pressure type, so its adjustment range tops out at 0.4 MPa, which suits circuits that must never see full line pressure. It is a size 200 body with a 1/8 in NPT port, fitted with the embedded square gauge on the MPa scale, and it carries no mounting bracket - the GR body can also be panel-mounted. 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 family.
This is a genuine AirTAC part. The GR line spans sizes 200 to 600 with port sizes from 1/8 in to 1 in, and options include standard or low-pressure regulation, embedded square or external round gauges with MPa, psi or bar scales, a reverse/check valve, a mounting bracket, and PT, G or NPT threads. Because AirTAC publishes flow as curves rather than a single rated figure, we confirm the datasheet and flow 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.

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

| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

Spray guns and atomising heads on a finishing line run at low, steady pressure. This low-pressure regulator on the 1/8 in gun feed holds the setting below 0.4 MPa so coating quality stays consistent through a shift.
Baggers and carton sealers often carry a secondary circuit - hold-down pads or delicate grippers - that must not see full header pressure. A size 200 GR regulator on that branch keeps the setting stable while the main line runs higher.
A bench that leak-checks or function-tests small pneumatic components needs a fine, repeatable low setting. The MPa square gauge and low-pressure range of this regulator let an operator dial in and hold test pressures below 0.4 MPa.
Start with the port step: size 200 with a 1/8 in port is the smallest GR frame, so match it to the line size and let the required flow - not the port alone - decide whether to step up to 300, 400 or 600. This code is the low-pressure (L) type, limited to 0.4 MPa downstream; if your actuator needs up to 0.9 MPa, choose the standard type instead. The embedded square gauge on the MPa scale is fitted here; psi or bar scales and an external round gauge are order options. Thread is NPT on this unit, with PT (standard) and G available to order. No bracket is fitted, but the body is panel-mountable. AirTAC publishes regulator flow as curves, not a single rating, 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 regulator flow as curves, not as a single rated number, so we do not quote a figure that could mislead your sizing. Tell us your line size and application and we will confirm the datasheet and flow curves for this exact model on request before you order.
The L in the code marks the low-pressure type, whose adjustment range tops out at 0.4 MPa - right for spray, clamping and test circuits that must stay low. If your process needs up to 0.9 MPa, order the same size in the standard type instead; maximum inlet pressure is 1.0 MPa (145 psi) either way.
