The AirTAC GR20008LNT AirTAC Air Pressure Regulator NPT1/4 Low-Pressure 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, ordered without a 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 GR20008LNT is an AirTAC GR-series air pressure regulator, and this unit is regulation only: it steps downstream pressure down and holds it steady. It is the low-pressure (L) type, so its adjustment range tops out at 0.4 MPa, and it is built for a 1/4 in NPT port on the 200 size body. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature window is -20 to 70 C, and no gauge is fitted (code N), so read the outlet on your own instrumentation or add a gauge configuration if you want a local display. A mounting bracket is included, and the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with larger ports and higher flow capacity as the size number rises, in standard and low-pressure types, with PT, G (BSPP) or NPT threads, gauge and no-gauge options, and an optional reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures against your application before you order.

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. |

| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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.

Holds a gentle, repeatable clamp pressure on fixture cylinders where the setting must stay low; the low-pressure type keeps the circuit from being set above its safe range.
Regulates the low-pressure air fed to blowing and cleaning jets along the loom, with the bracket securing the unit beside the machine's air header.
Trim the low-pressure air sweeping a benchtop drying or environmental cabinet, using your own panel gauge since this configuration ships without one.
Start with the port and flow step: 200 is the smallest GR size with a 1/4 in port, so step up to GR300, GR400 or GR600 if your line needs more flow - we can check the flow curves against your demand before you commit. This unit is the low-pressure (L) type, correct where the downstream setting must stay at or below 0.4 MPa; if your process needs settings up to 0.9 MPa, choose the standard GR type instead. Thread is your call: PT is the catalogue standard, while G (BSPP) and NPT (as on this unit) are order options. A gauge is not fitted on this code; gauge and scale choices exist on other configurations, and a mounting bracket is included. Because 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 GR flow as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your inlet pressure, set pressure and demand, and we will confirm the datasheet curve figures for this 1/4 in, 200-size unit before you order.
L marks the low-pressure regulator type: its adjustment range tops out at 0.4 MPa instead of the standard GR range, which suits circuits that must never be set high. N is the no-gauge code, so this unit has no pressure gauge fitted - choose a gauge configuration with your preferred scale if you want a local readout.
