Mechanical Extraction

Mechanical Extraction Unit The mechanical extraction version of lapVent has a unique sloping outlet to prevent moisture from dripping back down into the system.
 

A passive mechanical venting airflow can go either way, depending on prevailing winds or structural layouts, etc., so 'in' and 'out' flows can be improved by installing vents on either side of a roof , with trunking going to separate service points or both to the same one.

In extreme conditions prevent condensation forming by lagging exposed trunking with insulation material.

Keep the lengths of ductwork to a minimum by laying it as direct as possible.   Prevent kinks and drooping in flexible pipework to avoid pooling.

 

Mechanical Extraction Unit Other roof space ventilation products do not provide a sloping outlet so moisture tends to drip back into the ductwork when warm moist air meets cooler air.
Safely and simply installed from inside at any time or from the outside during construction. lapVent - mechanical extraction unit
