Control condensation and black mould in properties without loft space with our wall-mounted Positive Input Ventilation (PIV) units. These compact systems deliver a constant supply of filtered, tempered fresh air, diluting humidity and pollutants while gently pushing stale, moist air out through natural leakage paths. The result is a drier, healthier home with improved indoor air quality and fewer issues like peeling paint, musty odours and streaming windows.
Why choose a wall-mounted PIV:
Designed for flats, apartments and basements where loft-mounted units aren’t possible
Quiet, energy-efficient EC motors keep running costs low
Optional integral heater for comfort on colder days
Smart humidity/temperature sensors with boost and timer modes
High-grade filters to reduce dust and allergens; simple, low-cost maintenance
Discreet wall installation with a single diffuser for whole-home impact
Ideal locations: hallway, landing, or central living space to distribute fresh air evenly throughout the property.
