The AirTAC GR20006C1TK 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 - 0.9 MPa (7 - 130 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 GR20006C1TK is an AirTAC GR-series air pressure regulator: it does one job, holding your set downstream pressure steady as upstream supply and air demand move. This 200-size unit carries a 1/8 in NPT port, and the code confirms a standard-type regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi). The C1 in the code means a round external gauge fitted on an MPa scale, so you can read and dial in the setting directly at the unit. The K code adds a reverse (check) valve, which lets downstream pressure hold rather than dump back through the regulator when the supply is shut off, and the bracket is included for panel or surface mounting. As a GR unit it contains no filter and no bowl, so it protects nothing from dirt or water - pair it with an upstream filter if the air line needs one. Operating temperature 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, in PT (standard), G (BSPP) or NPT thread, with optional low-pressure type, gauge scale in MPa, psi or bar, and reverse-valve versions. 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.

| 06 | Port size PT1/8". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |

| C | Gauge shape: Round. 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.

Set and hold the working pressure feeding a small stamping or punch press cylinder, with the check valve keeping the cylinder circuit pressurised if the main supply is isolated.
Give a laboratory or QC test bench a stable, repeatable air pressure at the point of use, read directly off the round MPa gauge for consistent test conditions.
Regulate the supply to small gripper or pusher cylinders on a bottling or cartoning conveyor, where a gentle, fixed pressure prevents product damage.
Start with the port step: this unit is 200 size with a 1/8 in (06) port, and the GR family steps up through 300, 400 and 600 with larger ports and more flow capacity - pick the size whose flow curve covers your consumption rather than oversizing blindly. Because flow is published as curves and not a single rating, send us your line pressure, set pressure and air demand and we will confirm the right size before you order. Other real choices on this family: the standard type covers 0.05-0.9 MPa (7-130 psi) adjustment, while the L low-pressure type caps at 0.4 MPa if your process runs low; gauge scale can be ordered as 1 (MPa, as fitted here), 2 (psi) or 3 (bar); thread can be PT (the standard), G (BSPP) or NPT, which is what this code specifies; the K option adds a reverse/check valve, fitted on this unit; and the included bracket suits mounting, with GR also panel-mountable.
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, not as a single rated number, so we will not quote a figure that is not in the datasheet as a rating. Send us your inlet pressure, set pressure and air consumption and we will confirm the flow data for this 200-size, 1/8 in port unit against your application on request.
C is the round external gauge, 1 sets its scale to MPa (psi and bar scales are orderable as 2 and 3), and K means a reverse/check valve is fitted so downstream pressure is held when supply is removed. PT is the standard thread for the GR series; G (BSPP) and NPT, which this unit carries, are catalogue options specified at order.
