"Thank you for your help with my purchase of this unit. The parcel arrived last Thursday morning; and unit was fitted and working by Saturday tea time, and by Sunday evening our condensation problem was almost over."

Positive Pressure or Positive Input Ventilation fans are generally loft mounted in a house or fitted within a cupboard in an apartment or basement.
They draw fresh air from atmosphere and push it into the dwelling via a ceiling or centrally mounted diffuser.
With a continuous supply of air into the dwelling it becomes positively pressurised forcing moisture and stale air out through the natural forms of ventilation, such as window mounted trickle vents.
This leaves the home free of high levels of humidity and creates an environment where condensation and mould can't form.
