The AirTAC GR20006LF1TK AirTAC Air Pressure Regulator, NPT 1/8 in 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 GR20006LF1TK is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from your compressed-air supply, and it contains no filter, no bowl and no lubricator. This 200-size unit is the low-pressure type (code L), so its adjustment range goes up to 0.4 MPa, and it is built for a 1/8 in NPT port (T). The embedded square pressure gauge reads in MPa (scale 1), a reverse/check valve (K) is fitted to hold the downstream setting if the upstream supply is interrupted, and the mounting bracket is included; the GR body is also panel-mountable. 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 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, standard or low-pressure regulation, gauge choices (embedded square or external round, in MPa, psi or bar scales), a reverse-valve option, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet numbers for 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.

| 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. |

| 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.

Packaging machines often clamp or hold cartons with air cylinders that must not crush the product. This low-pressure GR regulator lets an operator set and hold a gentle downstream pressure within its 0.4 MPa range, while the fitted check valve keeps the setting stable if the main supply dips during a machine stop.
Test benches and lab fixtures need a repeatable, low set pressure for instruments, air bearings or specimen fixtures fed from a shop-air drop. The 1/8 in NPT port suits compact bench plumbing, the MPa square gauge gives a clear set-point readout, and the -20 to 70 C range covers unheated rooms and enclosures.
Pneumatically piloted process valves and actuators on a production line need a steady, low pilot pressure independent of the main header. This GR regulator, panel-mounted or bracket-mounted near the valve bank, holds the pilot pressure with the check valve protecting the pilot circuit against upstream pressure loss.
Start with the port step: this unit is 200 size with a 1/8 in NPT thread; if your line needs a larger bore or more flow capacity, step up through the 300/400/600 GR sizes and match the port (06=1/8, 08=1/4, 10=3/8, 15=1/2, 20=3/4, 25=1 in). Because this is the L low-pressure type, choose it when your set point stays within 0.4 MPa; for higher set points pick the standard GR type. Decide the gauge: this configuration carries the embedded square gauge on the MPa scale, with psi or bar scales and an external round gauge available as ordering options. Choose the thread to match your piping: PT is the standard, while G (BSPP) and NPT are catalogue options; this unit is ordered with NPT. The reverse/check valve (K) is fitted here; omit it if you do not need downstream hold-up. A bracket is included and the GR can also be panel-mounted. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against 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 regulator flow as characteristic curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your set pressure and the flow your application needs, and we will confirm the sizing against the datasheet curves on request before you order.
L marks the low-pressure regulator type. Its adjustment range goes up to 0.4 MPa instead of the standard GR range, so it is the right choice for circuits that must never be set above that level. The rest of the code decodes as: 200 size, 06 = 1/8 in port, F1 = embedded square gauge with MPa scale, T = NPT thread, and K = reverse/check valve fitted.
