Fan Forced Ducted System

Sub floor fan forced ducted ventilation systems.

As it is important to have adequate cross ventilation to the sub floor area of buildings to reduce the risk of fungal decay and termite attack, some buildings, cannot achieve a proper cross flow due to raised levels of the ground against the exterior walls, or walled off sections butting areas of concrete floors on fill.

Semi detached and terrace houses are typical constructions which often cannot achieve proper cross flow due to other buildings and concrete areas.

The installation of our fan forced ducted ventilation system is designed to improve the air flow to all these areas where dead pockets of stale damp air is trapped. This is achieved by exchanging air in the sub floor with the air outside via a system of flexible ducting which has an inline fan installed in the ducting and connected to your 240v power point with a time clock. The ducting and the fan are hung from the underside of the floor and in most cases, there is no visible indication or change to the external appearance of the building, ideal for heritage listed buildings.

Each system, including the layout and placement of the ducting and the periods of operation is individually tailor made to each particular building and the installation is carried out by employees of this company, we do not use any sub-contractors.
