Axial bathroom fan HV 300AE for window or wall mounting 40021090

Flexible Ventilation Solution for Windows and Walls

The HV 300AE axial fan is designed for locations where traditional wall mounting is impossible or insufficient. Its unique construction allows direct installation into an opening cut in a window pane, making it an ideal choice for bathrooms, toilets, or utility rooms lacking natural gravity ventilation. This solution eliminates the need to alter wall structures or install additional ventilation ducts—the fan operates directly with the external environment.

The device is also ready for wall mounting, providing installers with complete freedom in selecting the installation location. A key structural component is the backdraft shutter, which automatically closes the airflow when the fan is not operating. This simple yet effective safeguard prevents air backflow (so-called "backdrafts") and the ingress of cold air, noise, or insects into the room.

Performance and Control for Various Needs

The HV 300AE model belongs to the single-speed series (AE version), ensuring ease of operation and reliable performance. The single-phase electric motor, operating at 230V and 50Hz, delivers a constant airflow capacity of 1150 m³/h. This power is sufficient for effective air exchange even in larger bathrooms or rooms with elevated humidity.

The motor's operating parameters are optimized to ensure energy efficiency while maintaining high effectiveness—it consumes only 68 W of electrical power. With a static pressure reaching up to 46 Pa, the fan effortlessly overcomes flow resistance in short ducts or when installed directly in a window pane, where conditions are more challenging than with a standard wall opening. The noise level generated during operation is approximately 46 dB(A), ensuring quiet performance that does not disrupt the comfort of the room.

Compared to smaller models in the same series, the HV 300 AE version offers higher static pressure (46 Pa), which is crucial for window-pane installations where flow resistance may be greater than with a simple wall opening. This enables the device to effectively handle air exchange even under more demanding installation conditions, ensuring stable airflow where lighter constructions might struggle to overcome resistance.

Safety and Operating Conditions

User safety is ensured through Class II electrical insulation and an IP X4 protection rating. This means the device is completely resistant to water splashes from all directions—ideal for bathroom environments where water vapor and direct water contact are common. The motor also features Class B insulation, guaranteeing stable operation even at elevated ambient temperatures.

Fan installation does not require complex tools or specialized electrical knowledge beyond basic installation skills. The device is ready for connection to a standard 230V network. Thanks to its compact dimensions (approximately 46 cm diameter for the HV-300 version), it does not visually dominate the window opening or wall, remaining a functional element of the building's technical equipment.

For installers, it is also worth noting that this model is part of Venture Industries' broader product range, facilitating the selection of accessories or replacements in the future. However, if the ability to change airflow direction or adjust rotational speed is required, it is advisable to consider other versions of the series (e.g., models M or A), which offer additional pull-cord or wall-mounted control features. The AE model remains the simplest and most economical choice where pure exhaust or supply functionality is needed without unnecessary control complications.
