With the Vitovent 300-C mechanical ventilation unit, AHI-Carrier offers a solution that’s particularly suitable for controlled ventilation of apartments. Particularly after implementing energy-saving measures and insulating the exterior walls, the building envelope becomes more airtight and requires adequate ventilation to protect the building’s fabric. Otherwise, there’s a risk of mold growth due to excessive indoor humidity.
Product Features
The Vitovent 300-C impresses with its compact, slim design. It can be easily concealed in suspended ceilings, such as in a hallway, where ventilation ducts for the rooms on either side can be installed. Vertical wall installation is also possible, for example in a storage room.
The maximum air supply of 150 m3/h is sufficient for comfortable ventilation of rooms ranging from 65 to 90 m2 .
The Vitovent 300-C ventilation unit utilizes up to 89 percent of the latent heat in the exhaust air, warming the cold outside air using a cross-counterflow heat exchanger. This saves energy and reduces heating costs year-round.
The standard package includes an automatic bypass circuit for warmer months. Fresh, cool supply air can be directed past the heat exchanger directly into the room, achieving passive cooling.
Although this compact unit already operates very quietly, additional insulation measures may be necessary depending on the installation location. Suitable system accessories include a blind distributor for integration into the unit, as well as sound attenuators for the outside and exhaust air.
The Vitovent 300-C mechanical ventilation system also helps allergy sufferers breathe easier. The filtration system, which includes an additional pollen filter, removes allergens and harmful substances from the supply air, creating an irritant-free environment.
High ease of use
The following operating methods are possible for the Vitovent 300-C ventilation unit:
- Via the Vitotronic 200 (WO1C) heat pump control unit
- Via the ventilation programming unit, type LB1 (with a convenient graphic display)
