MyVallox 125 CFi
A novel solution for the energy renovation of ventilation systems
The different models of MyVallox 125 CFi can quickly and easily replace dozens of old ventilation unit models! The unit comes in seven models (A-G) that differ from each other only with respect to the duct outlets. The duct outlets of the MyVallox 125 CFi models are in the same places as in old ventilation unit models, or they require only minor changes in the duct. This means achieving energy-efficient ventilation with modern features is easier and faster, which also saves money.
Energy-efficient living comfort
A modern ventilation system measures the air quality automatically, and continuously supplies clean, filtered, and suitably warm air inside the home. When a ventilation system knows how to boost ventilation automatically when the carbon dioxide or humidity level of indoor air increases, it operates according to need and is always energy-efficient. Ventilation never becomes too intense, and the residents do not suffer from carbon-dioxide-induced fatigue or headaches.
You know the ventilation system is working effectively if you cannot even notice it. The new constant flow feature keeps the air volumes in balance in all conditions, even during the defrosting of the heat recovery cell and regardless of the heat recovery bypass status. In other words, ventilation works always as it should.
With the current EC motors, the electricity consumption of the energy-efficient Vallox 125 MV fans is very low. The advanced defrosting automation ensures that Vallox 125 MV will not stop the supply air fan even in the coldest weather.
The heat recovery efficiency of the unit’s cross-counter flow cell is excellent at nearly 80%. In comparison, the efficiency of older units is around 50% or even lower. This figure indicates how efficiently the heat recovered from extract air can heat the supply air. Thanks to the efficient heat recovery, the energy consumption of ventilation is low even at the higher outputs, and separate preheating is no longer needed. This also saves electricity from the main heat source of the apartment.
Modern features
Although it is often unnecessary to control the ventilation system thanks to modern automation features, the Vallox unit comes with diverse control options, including remote control through a free cloud service and control through building automation. The MyVallox 125 CFi unit can also be controlled from a separate wall-mounted control panel (delivered with the unit) or a Vallox cooker hood (PTXP MC, PTCPA MC and PTD EC).
Indoor air quality is monitored by the integrated humidity and carbon dioxide sensors that boost ventilation when necessary. The unit measures the air temperature and adjusts heat recovery automatically. You no longer have to worry about manually adjusting the summer/winter damper – the unit bypasses the heat recovery cell automatically if the supply air is warmer than the set supply air temperature. The unit also has an automatic cold recovery feature that is useful in summer when the outdoor temperature is higher than the indoor temperature in the daytime.
The new, larger high-quality filters ensure a high filtering efficiency, keeping the indoor air clean of the impurities of outdoor air for a long time. MyVallox 125 CFi’s features match the modern requirements for ventilation perfectly.
Replace dozens of old ventilation unit models
For instance, the new Vallox 125 MV ventilation unit can replace MUH Ilmava, Ilmava 100, Ilmava 120, Vallox Digit, Vallox 75, Vallox 95, Vallox 121, Ilto 440, Ilto 270, Ilto 280 and Onnline 130 and dozens of other old ventilation units. With minor changes in duct outlets Vallox 125 MV can replace over 50 old ventilation unit models.

Installing a new ventilation unit in place of an old one
Ceiling mounting plate for easier installation
Optional ceiling mounting plates (excluding model B) and insulated attic floor penetration plates (all models) are available for the MyVallox 125 CFi unit.
If the locations of ducts are even slightly misaligned with the duct outlets of the new unit, the ceiling mounting plate helps to place the ducts exactly in the right places before installing the unit. If the ceiling mounting plate can be suspended from the ceiling structures, it is easy to mount the heavy unit on the ceiling mounting plate that is in place.

How much energy is saved when old ventilation unit is replaced with a new one?
The adjacent energy consumption calculator allows you to calculate the energy consumption of your current ventilation unit in the Finnish climate and determine how much you can save by replacing your old unit with a new energy-efficient Vallox ventilation unit.
The calculator is an Excel file so Microsoft Excel needs to be installed on your computer in order to use it.
