The Vitovent 300-C impresses with its compact, slimline design. It can be concealed quite easily in suspended ceilings. For example in a hallway, where the ventilation ducts to the rooms on either side can also be installed. Vertical installation in a wall is equally possible, for example in a storeroom.

With the Vitovent 300-C mechanical ventilation unit, Viessmann offers a solution that is particularly suitable for the controlled ventilation of apartments. Especially after implementing energy saving measures in a building and insulating exterior walls, the shell of the old building becomes more airtight and requires adequate ventilation to protect the building fabric. Otherwise, there is a risk of mould growth due to excessive humidity in the interior.
Product features
The unit's maximum air delivery of 150 m3/h is sufficient for ventilating interiors of between 65 and 90 m2 quite comfortably.
The Vitovent 300-C ventilation unit utilises up to 89 percent of the latent heat in extract air, warming the cool outdoor air with the assistance of a cross-countercurrent heat exchanger. This saves energy and reduces heating costs all year round.
An automatic bypass circuit for the warmer months of the year is integrated as standard. Fresh, cool supply air can then be routed past the heat exchanger and directly into the interior, thereby achieving a passive cooling effect.
Although this compact unit already operates very quietly, additional insulation measures can be implemented depending on the intended installation site. Matching system accessories include a silenced distributor for integration into the unit as well as outdoor and exhaust air silencers.
The Vitovent 300-C mechanical ventilation system also allows allergy sufferers to breathe more easily. A filtration system, featuring an optional pollen filter, cleans the supply air of allergens and noxious substances, thereby creating an irritant-free indoor environment.
High operating convenience
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 convenient graphic display)
