With both mould and condensation a serious health concern, as well as causing damage to building interiors, wall ventilation is an easy method of tackling the issue.. Air is drawn into the Positive Input Ventilation Unit (PIV) via an external inlet and through a short length of duct. The specially developed power pack cartridge assembly draws the air through an integral, high capacity, washable filter. The precision engineered scroll/impeller assembly and anti-vibration EPP body guarantees ultra low sound levels and increased energy efficiency.. The fresh, filtered airflow passes along the ducting and enters the room through a discreet grille. The rotatable integrated grille can be turned to one of 8 positions ensuring that the airflow is always directed upwards, reducing cold draughts..
