Helios Fans HR 90 KEZ, with electr. damper

The Helios HR 90 KEZ is a compact mini fan designed for duct installation with a nominal diameter of 100 mm. Its waterproof casing, made from impact-resistant polymer, is rated IP45 and features an integrated grille. The fan blades are oriented upwards, fully concealing the interior and built-in guide vane for a clean appearance.

Equipped with spring clips for easy, tool-free mounting, the unit meets DIN EN 294 standards for protection against accidental contact. It includes a built-in overrun timer, allowing adjustable overrun times from 2 to 8 minutes to ensure optimal ventilation.

The fan uses a highly efficient axial impeller with 5 blades made from durable polymers. Powered by an AC shaded pole motor with thermal overload protection, it is suitable for continuous operation. Maintenance-free, sealed-for-life ball bearings guarantee long-term reliability. This model is not reversible and features an electrical damper for controlled airflow.
