About the ventilation unit
The damppro loft unit is a Positive Input Ventilation (PIV) unit which
creates fresh and healthy living environments by supplying filtered air
into a property at a continuous rate through a ceiling mounted diffuser.
The diffuser is normally installed in a hallway or landing area.
The units have been developed to improve indoor air quality and resolve
condensation and mould problems. They are designed to operate
continuously for 5 years with no requirement for maintenance other
than general cleaning the filter must be replaced after 5 years usage.
In conditions between 19°C - 25°C the units will increase air flow rate
by 10%. In hot conditions above 25°C the units will temporarily switch
off to avoid bringing hot air into the property from the loft space.
