Helios Fans RVE 80

The Helios Fans RVE 80 is a compact ventilation valve designed for quick and easy retrofitting into existing Ø80mm ductwork. It features a durable plastic ring with a secure all-round double lip seal, ensuring an airtight fit within the duct. A tight-fitting rubber membrane opens automatically under negative or positive pressure, allowing efficient airflow control. Each unit includes two interchangeable membranes to provide different flow rate options, ensuring versatility across a range of ventilation needs. When installed horizontally, the membrane support web must be oriented vertically for proper operation. Suitable for environments with temperatures ranging from ‑20°C to +90°C, the RVE 80 is a practical choice for improving airflow performance in residential and commercial ventilation systems.
