Vallox 99 MV CF

Vallox 99 MV CF

The Vallox 99 MV CF ventilation unit with constant flow fans keeps the ventilation of your home in balance. The energy-efficient unit compensates for pressure differences in the air, keeping pressure ratios constant during the defrosting of the heat recovery cell regardless of the heat recovery bypass status. The constant flow feature of the ventilation unit also compensates for separate extractions and the accumulation of dirt on filters.

Designed on the basis of customers’ wishes, Vallox 99 MV CF has the lowest frame structure in the market with tested quietness* and easy installability on top of a bathroom washing tower, for instance. Thanks to the thorough air technical design by Vallox, the ventilation unit does not require additional soundproofing, even in demanding locations. The energy-efficient ventilation unit includes all the modern features of the MyVallox units, such as integrated RH and CO2 sensors and comprehensive control options. The annual efficiency of Vallox 99 MV CF is 76%.

The Vallox 99 MV CF ventilation unit may be connected to house automation (Modbus RTU RTU, KNX) and registered with the free MyVallox Cloud service, which makes control and maintenance of the unit easier. The cloud service allows remote control of the unit and, subject to the user’s permission, technical support can connect to the unit if problems arise. Alternatively, the ventilation unit can also be controlled via its own control panel or a cooker hood. It is also possible to leave the control entirely to the integrated air quality sensors, so that the unit will boost the ventilation independently when necessary.

* Sound pressure levels have been tested in accordance with the ISO 5135:1997 and ISO 3741:2010 standards.

Note! Wall mounting plate must be ordered separately.
