Ventilation openings

Please take into consideration that ventilation openings may reduce the window’s sound insulation and heat retention properties. It must also be considered that the air amount that can pass the ventilation opening is contingent upon the negative air pressure in the room interior. A ventilation opening does not replace a contemporary ventilation system and with the absence of ventilation the interior air may begin to flow out. 
 
BIOBE VS
Biobe VS is a fresh air ventilator that can be placed into the slot milled to the window frame or into slot between frame and wall construction. Biobe is suitable both for new construction and renovation. Using Biobe VS fresh air ventilators the encoming air will flow as controlled into the room both in the gravity and the mechanical ventilation and the amount of fresh air can be quaranteed. Incoming air can be calculated as per room and department. 
The filtering unit decreases the pollutants from incoming air. Pointing the flow gap upwards the fresh air mixes intothe warm inside air up in the room and reduces the feeling of draught. 
The complete VS frame ventilator set includes ventilator (V), filter unit (S) and canopy with insect net (B) or without net (U).
