The AirTAC GR200-08 AirTAC Air Pressure Regulator, NPT1/4, psi Gauge 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 GR200-08 is an AirTAC GR-series air pressure regulator for compressed air only: it holds a steady downstream pressure regardless of swings in supply pressure. This 200-size unit is decodes to a 1/4 in NPT port, a standard-type regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi), a fitted round pressure gauge reading in psi, and a built-in reverse (check) valve that lets downstream air pass back through the body. No mounting bracket is supplied with this configuration, and the body can be panel-mounted. As a pure regulator, the GR has no filter bowl and no lubricator - it does one job: regulation.
This is a genuine AirTAC part. The GR family spans four sizes (200, 300, 400, 600) with ports from 1/8 to 1 in, optional G (BSPP) or NPT threads in place of the PT standard, low-pressure variants, gauge scale choices, and bracket options. Flow for these regulators is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures against your application before ordering.

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. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

| 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.

Set a stable 1/4 in-line supply pressure ahead of a directional-valve manifold on a packaging or assembly machine, so solenoid valves and cylinders see one consistent setpoint through the shift.
Regulate the air feeding short-stroke stopper, gate and pusher cylinders on a conveyor line, where a repeatable pressure keeps indexing gentle and consistent part after part.
Drop a point-of-use regulator into a 1/4 in takeoff from a factory air ring main to run air tools, blow-off nozzles or small actuators at a pressure set locally, independent of the header pressure.
Start with the port and size step: the 200 size takes a 1/4 in port, and stepping up to GR300/GR400/GR600 buys larger ports and higher flow capacity - match the step to the air demand of the circuit rather than the fitting alone. This unit ships as a standard-type regulator with a 0.05-0.9 MPa (7-130 psi) range; if your setpoint sits at or below 0.4 MPa, a GR low-pressure (L) variant is the finer-control choice. The fitted round gauge here reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. Thread is NPT on this code - PT is the standard thread and G (BSPP) is the alternative order option. A reverse/check valve is fitted (code K), which matters if backflow through the regulator must be possible; leave it out on codes without K. Brackets are optional (this code omits one) and the GR is also panel-mountable.
One honest note on sizing: AirTAC publishes regulator flow as curves, not as a single rated number, so we do not quote a flow figure 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 regulator flow as performance curves rather than a single rated figure, so we do not state a Cv, l/min, m3/h or SCFM number on the page. Tell us your application and we will confirm the relevant flow and sizing data from the datasheet on request before you order.
This code (C2) fits an external round pressure gauge reading in psi; square embedded gauges and MPa or bar scales are the alternative catalogue choices. The K in the code means a reverse (check) valve is fitted, allowing downstream air to pass back through the regulator - useful where the circuit must vent or backflow. The unit is standard range (0.05-0.9 MPa / 7-130 psi), has a 1/4 in NPT port, and no mounting bracket is included.
