Prices & Options
The Helios EVK 500 ventilation cover is engineered to protect supply and extract air openings in ventilation systems. It features a frame, blades, and actuators made from light grey plastic, and an actuator housing rated IP55, suitable for outdoor installation. The number of louvres varies depending on the size to optimize airflow performance. This cover supports automatic operation with the fan through a localised changeover switch that controls the servomotor, switching the fan circuit via a limit switch. The signal box comes fully wired and includes a 1.5‑meter connection cable for easy installation. Operating at 230 V, 50/60 Hz, it supports a maximum supply air flow velocity of 6 m/s and a maximum exhaust air flow rate of 8 m/s.
