Description

AlphaAir Freshbox 25 ventilation unit

The AlphaAir Freshbox 25 with heat recovery can automatically regulate the air supply according to the current temperature parameter. Increase not only the energy efficiency in the long term with this ventilation unit, also ensure the protection of your building fabric.  The AlphaAir Freshbox 25 is also ideal for preventing or combating mold. In addition, the fan convinces with a timer function and an automated protection against frost.

If the radon activity concentration in cellars and living rooms is low, the BMU recommends regular mechanical cross-ventilation (window ventilation) of the rooms. Radon-contaminated air is quickly transported outdoors in this way.

If radon levels are elevated, manual ventilation can no longer sufficiently reduce the radon concentration. Here it makes sense to find a technical solution. Automated ventilation ensures that there is a sufficiently high air exchange and thus the radon concentration can be permanently lowered. Since radon usually enters the building via the basement rooms and spreads to the higher floors via stairwells, cables and pipe connections, reducing the radon concentration in the basement helps to significantly reduce the total radon load in the building.

Sensor-controlled radon ventilation systems not only monitor radon levels, but sometimes also temperature and humidity. Climate-controlled ventilation systems with heat recovery and dew point control also prevent the entry of moisture into the basement, are easy on the wallet during the heating season and provide a pleasant feel-good climate in living spaces.
