The AirTAC GR20006LNTK AirTAC Low-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, 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 GR20006LNTK is an AirTAC GR-series air pressure regulator: it does one job, holding a steady downstream air pressure from a variable supply line. This unit is the 200 size with a 1/8 in NPT port, and the L in the code marks the low-pressure type, which regulates up to 0.4 MPa - suited to circuits that must never see full line pressure. The K code means a reverse (check) valve is fitted, so downstream pressure is held if the upstream supply is lost, and the N code means no gauge is supplied; a gauge can be ordered if you want a direct reading. A mounting bracket is included, and the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans the 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, in standard or low-pressure types, with or without a gauge, and with PT, G or NPT threads. 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. Flow is published as curves rather than a single rating, so ask us to confirm the figures against your application.

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. |

| 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. |

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.

Feeds pilot-air circuits on directional valve manifolds that are specified for a low setpoint, with the check valve holding pilot pressure if the main supply dips.
Steps machine air down to a safe low pressure for delicate clamping and hold-down cylinders on cartoning and wrapping lines, where full line pressure would damage product.
Sets a gentle, repeatable low pressure for blow-off and drying nozzles on conveyor lines, so operators get a stable setting instead of throttling a full-pressure line.
Start with the port step: the 200 size carries the 1/8 in port in this code, and larger sizes (300/400/600) step up to bigger ports for higher air demand - size against the flow your circuit needs, not just the pipe. Then check the type: this L-code unit is the low-pressure type, regulating up to 0.4 MPa; if your setpoint sits above that, the standard GR type covers up to 0.9 MPa. Decide on a gauge (this code has none fitted; square embedded or round external gauges with MPa, psi or bar scales are the catalogue options) and on the reverse/check valve, which is fitted here. Thread is NPT in this code; PT is the standard and G is the other order option, so match it to your fittings. A bracket is included and the body can also be panel-mounted.
One honest note on sizing: AirTAC publishes GR flow as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the sizing from the datasheet before you order.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR-series flow as curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your application - supply pressure, setpoint and the air demand downstream - and we will confirm the sizing from the datasheet on request before you order.
L marks the low-pressure type of the GR regulator: it regulates up to 0.4 MPa. If your required downstream setpoint sits above that, you need the standard GR type instead, which covers the full 0.05-0.9 MPa adjustment range. The rest of the code reads: 200 size, 1/8 in NPT port, no gauge fitted, reverse/check valve fitted, bracket included.
