Central Ventilation Fan AWENTA CVU400HT with Hygrostat and Timer 60W 230V AC 3-speed 265/360/415 m³/h

AWENTA CVU400HT is a central ventilation fan designed for ducted residential and light‑commercial ventilation systems. It integrates a hygrostat for automatic humidity detection and a timer for delayed switch‑off, offering three selectable speeds to match different airflow needs. With a rated power of 60W and three airflow settings — 265, 360 and 415 m³/h — the unit provides controlled extraction of stale or humid air from bathrooms, kitchens and utility rooms while fitting standard 230V AC electrical systems.

Advantages

The fan provides automatic humidity-based control via the built-in hygrostat, reducing manual intervention and helping to prevent condensation and mould formation. Three speed settings allow energy-efficient operation by selecting only the required airflow. The integrated timer ensures continued extraction after the source of humidity stops, improving indoor air quality. Compact central design permits connection to ductwork for quieter, centralized installation compared with multiple single-room fans.

Suitable for

• Bathroom and shower room moisture extraction
• Kitchen air extraction for cooking fumes and steam
• Utility rooms, laundry rooms and small commercial washrooms
• Centralized ducted systems serving multiple wet rooms

Key specifications

• Power consumption: 60 W
• Supply voltage: 230 V AC
• Three speed settings with airflow: 265 m³/h, 360 m³/h, 415 m³/h
• Built-in hygrostat for automatic humidity control
• Integrated timer for delayed shutdown
• Axial/centrifugal fan design suitable for ducted installation

How to use

Install the AWENTA CVU400HT in the central section of the duct network according to local electrical and ventilation standards. Set the desired speed according to required airflow and noise preferences; use a lower setting for continuous background ventilation and higher settings for rapid moisture removal. The hygrostat will activate the fan when humidity rises above the preset threshold; the timer will keep the fan running for the selected delay after humidity levels fall or after manual activation. Regular visual checks and periodic access to the ductwork ensure unobstructed airflow.

Usage recommendations

For reliable operation, place the unit in an accessible location for maintenance and ensure duct lengths and bends comply with manufacturer and local ventilation guidelines. Use the lowest effective speed for continuous ventilation to conserve energy and select higher speeds for short-term intensive extraction. Clean or inspect ducts periodically to maintain rated airflow and avoid increased noise or motor load.
