What are ducted fans?
Room ventilation fans bring in fresh air and remove stale, warm or moist air from specific spaces: bathrooms, kitchens, offices, boardrooms, stores and labs. Each space has its own needs, such as quiet running in a boardroom or moisture resistance in a bathroom.
Ducted fans and heat recovery units serve several rooms through ductwork. A heat recovery unit also transfers heat between outgoing and incoming air to save energy.
