Constant Airflow Regulators (RVC) provide a practical and efficient solution for controlling airflow in ventilation and air conditioning systems. Designed for direct installation in ducts—whether for supply or exhaust—RVCs ensure a constant air volume across a wide pressure range, from 5 to 20 mmwc. Their simplified operation allows precise adjustments for different airflow needs, delivering a comfortable environment with energy efficiency.
