AKOR - Whole House Ventilation with Heat Recovery

The AKOR is an extract and supply system with heat recovery. It will remove stale damp air from the wet rooms and supply fresh, warmed air to the dry rooms. For smaller rooms one supply point is sufficient, but for larger rooms such as a lounge, two or more points may be required. It expels warm moist air to the outside, bringing back fresh air that has been warmed in the heat exchanger, using the heat recovered from the expelled air. The two air streams do not mix and so the stale, expelled air cannot be brought back into the house. Up to 70% efficiency is typically achieved at low operational speeds.

Advantages of the AKOR Heat Recovery System:

• Specifically designed for domestic installation.
• Maximum airflow (up to 475 cubic m/hr ) is the highest in its class.
• Ventilation unit made from polypropylene which means it is lightweight and corrosion free.
• Heat recovery unit can be easily dismantled for passing through restricted openings (for example: loft hatches) and is just as easily reassembled for installation.
• Most of the duct runs are either 80 or 60mm so they can be routed through a normal 100mm stud partition or behind a soil pipe. Therefore they do not require an increase in the size of the boxing.
• Extract airflow is via 5 separate inlets on the ventilation unit (4 x 80mm and 1 x 125mm), each of which can be separately adjusted. Air flow from each ‘wet’ room can be independently controlled by a simple but effective constant volume device fitted to the inlets on the ventilation unit. Thus the airflow does not need balancing and is not prone to interference by children, decorators or ‘helpful’ friends.
• Ducting for the supply (fresh) air side is a short run of 150mm reducing to 1 or 2 runs of 125mm. 60mm ducts branch off the 125 main trunk to each of the dry rooms. This ensures that the air delivery throughout the system remains even. Balancing of air flow is not required.

How the Akor system works:

Powered by two integral fans (1 for supply and the other for extract air), the AKOR unit transfers the heat from the exhaust air to that of the fresh filtered incoming supply air using an efficient “cross-flow” style heat exchanger. As with the SIROC unit, the AKOR extracts from multiple points in bathrooms, toilets, utility and kitchens to one centrally located fan unit.

All AKOR units incorporate self-regulating air valves mounted in the spigots of the extract ports and are designed to provide a precise constant extract air volume for both small or large applications.

The AKOR series is available in two models (T3/7 and GD) with airflow performances ranging from 200 up to 450 m3/hr. All units include two (extract & supply) powerful 1phase 230V 50 Hz 3-speed external rotor motors coupled with a forward curved centrifugal impellers.

The picture above shows the AKOR with the casing removed to show the heat exchanger and workings.

The picture on the left shows the AKOR with the cover in place as it would be when it has been installed.

The AKOR is normally wrapped in insulation but this has been removed for the photograph.

Technical Data:

The AKOR casing is manufactured from high impact resistant ABS plastic and includes four 80 mm inlet ports (for bathroom, toilet and utility etc.); one 125 mm inlet port (kitchen) and one 125 mm outlet port for connection to the exterior of the building (for extracted air) and one 150 mm outlet port for connection to the exterior of the building.

Supply Air: one 150 mm inlet and one 150 mm outlet port. The AKOR multipoint extract and supply air fans aim to provide a "complete" twin fan, conditioned air ventilation solution for an entire residential installation. Trickle vents in windows are not required supply air.

To compliment the AKOR series a comprehensive range of specialist accessories (including extract values, ducting and mounting supports) are available to complete any given installation.

The AKOR meet the requirements of current Building Regulations: Document F1 when correctly installed to comply with BS5250 - the control of condensation in buildings.
