The AirTAC GR20008C2TK AirTAC Air Pressure Regulator NPT1/4 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 PT1/4" 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 GR20008C2TK is an AirTAC GR-series air pressure regulator for compressed air: it reduces and holds a stable downstream pressure and does nothing else - no filtration, no bowl, no lubrication. This size-200 unit has a 1/4 in NPT port, a standard regulation range of 0.05-0.9 MPa (7-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), and an operating temperature of -20 to 70 C, which is wider than the rest of the G family. It is fitted with an external round gauge reading in psi and a reverse (check) valve, and comes with a mounting bracket; the GR series is also panel-mountable.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, optional G (BSPP) or NPT threads in place of the PT standard, low-pressure variants, and gauge or check-valve choices. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

| 08 | Port size PT1/4". 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. |
| (blank) | Fixing bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 the clamping cylinders on a stamping or press cell at a set, repeatable downstream pressure, with the check valve holding the setting against backflow when upstream supply dips.
Feeds directional valves and small cylinders on a cartoning or wrapping machine with regulated air at the pressure the valve manufacturer specifies, monitored on the round psi gauge.
Regulates the supply to gripper and pick-and-place actuators on a robotic assembly cell, keeping part-handling pressure stable across the shift.
Start with the port step: size 200 with a 1/4 in NPT port suits smaller branch circuits, while 300/400/600 step up in port and flow capacity - match the step to the air demand of the circuit rather than to the pipe alone. Set the required downstream pressure inside the 0.05-0.9 MPa (7-130 psi) standard range; if your circuit runs below that, ask about the low-pressure (L) variant. This unit carries a round gauge scaled in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. The trailing K means a reverse (check) valve is fitted - useful where backflow must be blocked - and NPT is an ordered thread option alongside the PT standard and G (BSPP).
Because GR flow is published only as curves and not as a single rated number, send us your application details and we will confirm the correct size 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 GR regulator flow as curves, not as a single rated figure, so we do not quote a number. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
It decodes as: C = an external round gauge is fitted, 2 = the gauge scale is psi, T = NPT thread instead of the PT standard, and K = a reverse (check) valve is fitted. A mounting bracket is included, and the GR series is also panel-mountable.
