AirTAC GR200-08 Pressure Regulator (GR20008F1K)
The AirTAC AirTAC GR200-08 Pressure Regulator (GR20008F1K) 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.

About the AirTAC GR200-08 Pressure Regulator (GR20008F1K)
The AirTAC GR20008F1K is a pure air pressure regulator from the G series: it reduces and holds a stable downstream pressure from your compressed air supply, with no filtering or lubrication function. This 200-size unit has a PT1/4 port, the embedded square pressure gauge on the MPa scale, and a reverse (check) valve fitted so downstream pressure is held if the supply side drops. Maximum working pressure is 1.0 MPa (145 psi), the standard adjustment range is 0.05-0.9 MPa (7-130 psi), and operating temperature is -20 to 70 C.
This is a genuine AirTAC part. The GR family runs from size 200 up to 600, with larger port sizes, G (BSPP) or NPT thread options, an optional low-pressure type limited to 0.4 MPa, a no-gauge variant, and a no-bracket variant. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures on request 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.

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.
Size Class

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.

Where the AirTAC GR200-08 Pressure Regulator (GR20008F1K) Is Used
Pneumatic press holding pressure
Set and hold a fixed clamping pressure on a small bench pneumatic press so parts are formed consistently, with the check valve holding the set pressure if the supply line dips mid-cycle.
Assembly cell gripper circuit
Feed a 1/4" branch line serving gripper cylinders on a robotic assembly cell, keeping actuation pressure stable and independent of the main header pressure.
Process pilot-air supply
Regulate the pilot air feeding solenoid valves and positioners on a process skid, with the MPa gauge giving a direct readout of set pilot pressure.
Is the AirTAC GR200-08 Pressure Regulator (GR20008F1K) the Right Regulator?
Step up through the GR sizes (200, 300, 400, 600) as your port size and air demand grow - this unit sits at 200 size with a 1/4" PT port. Choose the gauge scale you want to read: 1 = MPa on this model, 2 = psi, 3 = bar. The K option adds a reverse/check valve; leave it off if backflow is not a concern. PT thread is standard, with G (BSPP) and NPT available as order options, and a no-bracket (J) version if you do not need the mounting bracket. GR is also panel-mountable. Flow for regulators is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" here)
- ✓ Standard 0.9 MPa or low-pressure 0.4 MPa
- ✓ Gauge fitted, or order N without
- ✓ Gauge shape C round / F square
- ✓ Scale MPa (1), psi (2) or bar (3)
- ✓ Reflux valve needed, order K
Installation & Maintenance Notes
- check Install downstream of the filter, following the airflow arrow.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure while air is flowing, then lock the knob.
- check Adjust within 0.05 - 0.9 MPa (7 - 130 psi) only.
- check Operating range -20 to +70 °C.
- check Panel-mount or use the fixing bracket; do not hang it on tubing.
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 GR200-08 Pressure Regulator (GR20008F1K) FAQ
AirTAC publishes regulator performance as flow curves rather than a single rated figure, so we do not quote a rated flow number here. Tell us your application and we will confirm the datasheet and flow curve so you can check sizing before ordering.
F is the square embedded pressure gauge and the digit after it is the scale: 1 = MPa, 2 = psi, 3 = bar. K means a reverse (check) valve is fitted, which holds downstream pressure if the upstream supply is lost. Codes without K have no check valve.
