Mechanical Extract Ventilation Systems provide dedicated extraction from areas where moisture is generated. The low energy fan unit is generally installed out of sight such as in a roof space and exhausts the contaminated air direct to the outside.  

Fresh air is supplied to the property via wall mounted or window trickle vents keeping a constant circulation of air.  These systems are an ideal alternative to the individual background ventilators as they cost less to supply and install, and have virtually no background noise. Central extraction systems ensure the right atmosphere with minimized ventilation and maximum retention of valuable warm air in wintertime.
