AirTAC GPR Series: High-Precision Air Regulator
The AirTAC GPR Series is a specialized pressure control component designed for applications that demand extreme accuracy and minimal pressure fluctuation. Unlike standard regulators, the GPR series uses a high-sensitivity pilot-operated diaphragm mechanism. This allows it to maintain a rock-solid set pressure even when the upstream supply pressure or downstream flow rates change significantly.
This series is the professional standard for tasks such as tension control, precision air bearings, laboratory testing, and delicate assembly processes where "pressure droop" must be eliminated.
Key Product Features
-
Exceptional Sensitivity: Capable of responding to minute changes in pressure with a sensitivity within 0.2% F.S.
-
High Repeatability: Ensures consistent performance across millions of cycles with a repeatability of ±0.5% F.S.
-
Minimal Pressure Droop: The pilot-operated design ensures the output pressure stays constant even as flow demand increases.
-
Superior Relief Characteristics: Features a high-capacity relief port to quickly exhaust downstream overpressure, maintaining tight system safety.
-
Low-Pressure Precision: Ideal for low-pressure applications, with specialized ranges starting as low as 0.005 MPa.
-
Stable Pilot Bleed: A constant, microscopic bleed of air keeps the internal pilot valve active and ready for immediate adjustment.
