AirTAC GR200-08 Pressure Regulator (GR20008F3K)
The AirTAC AirTAC GR200-08 Pressure Regulator (GR20008F3K) 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 (GR20008F3K)
The AirTAC GR20008F3K is an air pressure regulator from the G series, dedicated to reducing and holding downstream pressure - it carries no filter, no bowl and no lubrication function. This 200-size unit has a PT1/4 port, the embedded square gauge on the bar scale, and the K option: a reverse (check) valve fitted so the set downstream pressure is held if the supply side is lost. 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 to 600 with larger ports, G (BSPP) or NPT thread options, a low-pressure type limited to 0.4 MPa, and no-gauge or no-bracket variants. Flow is published as curves, not a single rating, so we confirm the datasheet and sizing figures 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.
Model Code: AirTAC GR200-08 Pressure Regulator (GR20008F3K)
| GR200 | G-series pressure regulator, 200 body — sets the port range. |
|---|---|
| 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. |

| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 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.

Where the AirTAC GR200-08 Pressure Regulator (GR20008F3K) Is Used
Safety circuit air reservoir feed
Charge a small downstream reservoir on a machine safety circuit, with the check valve keeping the stored set pressure available for a controlled stop even if the main supply fails.
Bottling line hold-down rollers
Regulate air to hold-down roller cylinders on a bottling line so bottles track steadily, with downstream pressure held through brief supply dips between changeovers.
Torque-tool feed on assembly bench
Supply a fixed pressure to pneumatic torque tools at an assembly bench, keeping fastener torque repeatable and holding the setting if the shop air drops.
Is the AirTAC GR200-08 Pressure Regulator (GR20008F3K) the Right Regulator?
Move up the GR size ladder (200, 300, 400, 600) as port size and air demand grow; this model is 200 size with a 1/4" PT port. This code combines the square bar-scale gauge (F3) with the K reverse/check valve - choose the plain F3 if backflow holding is not needed, or F1/F2 for MPa/psi scales. PT thread is standard, with G (BSPP) and NPT as order options; a J code removes the bracket and the GR is panel-mountable. Remember that regulator flow is published as curves rather than 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 (GR20008F3K) FAQ
No single rated flow figure exists in the catalogue: AirTAC publishes regulator performance as flow curves. Share your application and we will confirm the datasheet and flow curve on request so you can size the 200 unit correctly before ordering.
K means a reverse (check) valve is fitted. It holds the regulated downstream pressure if the upstream supply is lost or dropped, which matters for clamping, holding and safety functions. Codes without K are plain regulators with no check valve.
