The Eco fan is a low voltage air extraction unit, specifically designed to operate in the sub floor wall.
This unit is installed onto an external wall to the sub floor area and is operated on 12volt DC power, has quiet operation and is very efficient to run.
Available in brown and white
It is designed to draw up to 4000 litres of fresh air per minute allowing fresh air to replenish the sub floor areas through additional or existing static wall vents. When installing an Eco fan it is also advisable to change any existing clay style vents to the brass wire mesh vents due to the increase in air flow it will allow, making the system more effective.
Being an air extraction unit, vents are necessary, and similar to the cross flow required when using air bricks, the air must be able to pass unimpeded through the sub floor from the existing (or additional if required) vents to the Eco fan opposite. These vents must not be covered or concealed by landscaping or gardens.
Homes that are double brick, terraces, have dwarf walls, mounded earth piles in sub floor, on sloping blocks or have stored goods in the sub floor may not be able to achieve proper cross flow with the Eco Fan due to the above obstacles causing dead spots in circulation and may require a ducted system.
