The BROOKVENT aircycle ONE 150 is a continuous running, low energy, ultra-quiet, alternate flow supply and extract fan with heat recovery for use in habitable areas such as living rooms, bedrooms, dining rooms, basements and hallways.
 
How it works: the continous running decentralised heat recovery units (aircycle ONE) transfer thermal energy from air extracted from indoor rooms to incoming fresh air. Two units can work synchronised with balanced air flows and top acoustic comfort.
The system can also include a single flow decentralised unit mounted in the wet room. No air distribution system is needed.
Energy saving: the preheated supplied fresh air and continous air changes reduce the demand for additional heating. Aircycle ONE and airstream DMEV are equipped with EC brushless motors which significantly reduce the electricity consumption.
Indoor Air Quality: a correctly specified mechanical ventilation system can ensure the quality of the indoor air is constantly maintaned for the health and well-being of the occupants as well as of the building. Duly maintained filters on aircycle ONE ensure that incoming air is suitably filtered before it enters the home.
 
Every 70 seconds the unit alternates between supply and extract fan modes.
When in extract mode the unit’s high efficiency ceramic heat exchanger collects and retains heat from the extracted air.
The majority of this heat is then transferred to the incoming air during supply mode.
This method of operation avoids the short circuiting of air that can often happen with conventional single room heat recovery units, resulting in much more effective room ventilation.
Units can also be set to work in harmony with each other e.g. when a unit in one room is extracting air another unit in another room can be set to supply air. This can greatly enhance cross ventilation and ventilation effectiveness in a home
