Helios Fans AEB15/30

The Helios AEB15/30 air extract element is a ready-to-install ventilation solution featuring an integrated motion sensor and timer for efficient, demand-controlled airflow. Constructed from durable white polymer, it fits ducts with a nominal diameter of 125 mm and includes a rubber seal on the mounting ring to prevent air leakage.

This unit provides a base airflow which increases automatically when motion is detected, enhancing ventilation only when needed. After 30 minutes without movement, the fan returns to its standard airflow setting. The element is powered by two LR03 (AAA) batteries, offering an operational life of approximately 18 months. Designed for both wall and ceiling installation, the AEB15/30 offers convenient, energy-efficient ventilation control without requiring an external power supply.
