    Positive Input Ventilation (PIV_N)

    Positive Input Ventilation (PIV_N) is a ventilation system that introduces fresh, clean, and filtered air into a home to dilute, displace, and replace stale, polluted, and humid air. Suitable for installation on the floor or in the ceiling, in any location.

    Energy-saving: The EC brushless motor significantly reduces electricity consumption

    Indoor Air Quality: a correctly specified mechanical ventilation system can ensure the quality of the indoor air is constantly maintained for the health and well-being of the occupants as well as of the building. Duly maintained filters ensure that incoming air is suitably filtered of pollutants before it enters the home.

    PIV Ventilation systems

    Application: Does not require any ducting system (renovation)

    How it works: A continuous running centralized single flow supply ventilation unit gently introduces fresh, clean, filtered air into the dwelling through a ceiling diffuser, to push out and replace the internal stale, contaminated, humid air. The loft mounting provides discrete installation and very quiet operation

    • Outer fan casing manufactured from powder-coated galvanized sheet steel providing long-lasting and robust construction. The unit is finished in white
      RAL 9010.
    • The top cover made from strong durable ABS technopolymer.EC external rotor motor, provided with integral thermal protection mounted on sealed for life ball bearings, and antivibration supports.
    • Forward curved centrifugal impeller dynamically balanced and directly driven by the motor to provide a smooth airflow through the unit. External anti-dust washable pre-filter, easily removable without tools.
    • Internal ISO Coarse 60% (G4) filter as standard. Design ceiling diffuser made of high-quality ABS technopolymer.
    • 2,5m flexible duct to connect ventilation unit and diffuser
