Axial bathroom fan HV 300RC for window or wall mounting 40021100

Axial fan for window or wall mounting

The HV 300RC fan is a solution designed for air exchange in bathrooms where mounting flexibility is required – it can be installed either in a cut-out in the glazing or directly on the wall. Its special construction allows for safe and airtight installation even in glass panes, without the need to modify the window frame.

The device operates as a supply-and-exhaust unit, meaning it can either remove contaminated air or introduce fresh air, depending on the setting. Control is via remote control, eliminating the need for additional wiring or wall switches. Two speed settings are available, allowing performance to be adapted to current conditions – for example, higher ventilation after bathing and a lower mode during everyday use.

The single-phase 230V / 50Hz motor is protected against electric shock in Class II, and the housing has an IP X4 protection rating – ensuring resistance to water splashes from baths or showers. The air-flow closing louvre operates automatically when the fan is switched off, preventing backflow of air and heat loss.

At maximum speed, the airflow performance is approximately 1100 m³/h at a static pressure of up to 700 Pa – sufficient to effectively exchange air even in larger bathrooms or with longer ventilation ducts. Power consumption at the highest speed is 30 W – low operating cost with high efficiency.

Installation is simple: the unit is ready for installation both in windows (using special mounting elements) and on walls (with the included screw kit). No additional control components are required beyond the remote control – everything is built-in.

Advantages for installer and user

• Glazing installation – the only type of axial fan on the market with this feature; no need to cut a hole in the wall or modify the window frame.
• Remote control operation – no need to run cables to a switch; ideal for renovations or when connection to an existing circuit is not possible.
• Two-speed operation – ability to choose between low and high speed; energy savings and quieter operation under lower load.
• Closing louvre – prevents backflow of air and heat loss; no need to add a separate damper.
• IP X4 – moisture resistance ensures the device will not be damaged even with frequent water splashing.
• Low power consumption – 30 W is less than an LED bulb; economical operation throughout the day.

Applications

Ideal for new constructions and renovations, especially where installation of a traditional wall-mounted fan is difficult or impossible – for example, in buildings with ceramic brick walls, concrete walls without the possibility of routing ducts, or in houses with large glass panes. It operates effectively even with longer ventilation ducts thanks to high static pressure. No service or maintenance is required – only cleaning of the louvre surface every few months.
