Ventilation of (moist) basement rooms with Maico AKE
Maico small room ventilator type AKE for basement rooms
As a rule, basement rooms are only rarely used actively or are only used as storage rooms. Accordingly, little attention is paid to the room climate. In most cases, cellars are not integrated into the heating system of the house. As a result, the room temperature is always much lower than in other rooms. However, cool air can absorb much less moisture than higher temperature air. As a result, the humidity in the cellar is deposited on objects and walls. Over time, this leads to mould and even damage to buildings. In addition even earth humidity does not have to penetrate by the cellar walls.
The described circumstances lead to the characteristic musty smell, which one knows from many cellars. Remedy could bring one systematic cellar ventilation . However cellar windows, if at all present, are usually very small. An effective ventilation is hardly possible with it. And even if, which house user would already think of the regular cellar ventilation? A dilemma, which haunts many house owners with the time.
The solution: Maico AKE
With the System AKE the well-known fan manufacturer Maico has launched a simple and effective solution for automatic and demand-oriented cellar ventilation. The system consists of only 3 main components: fan, wall sleeve and outer flap. For the wall sleeve, the basement wall must be pierced with a core bore 120 mm in diameter (AKE 100) or 180 mm (AKE 150). However, apart from the electrical connection, the necessary construction work has already been completed. The wall sleeve connects the internal fan with the external flap and serves to transport the humid air extracted from the cellar to the outside. The wall sleeve is extendable and can thus be adapted to different wall thicknesses.
Automatic, demand-dependent cellar ventilation
The big advantage, however, is the automatic function. A sensor is integrated in the fan and in the external damper. The sensors ensure that air is extracted from the cellar as soon as the humidity inside is higher than outside. At the same time, the intelligent control system prevents the room from drying out too much and switches off the fan if the absolute humidity in the room falls below 30%. As a second safety function, frost protection is integrated, which also switches off the cellar ventilation when the room temperature falls below 5 °C. The fan is switched off when the absolute humidity in the room falls below 30%. With an optional switch or push-button, the system can be switched manually if required.
Realisation of the necessary air post-flow
Where air is sucked off, the appropriate air flow must also be provided. Otherwise, a negative pressure would be created in the room in question. From bath ventilation, the passive air after-flow via door ventilation grilles or door leaf undercuts is known. The solution can also be used for cellar ventilation. Another passive option is to drill a second core hole in the opposite cellar wall to mount another wall sleeve with ventilation flaps inside and outside. An active air afterflow occurs when a plug-in fan is inserted in the second wall sleeve. The control of the AKE System switches both ventilators on or off simultaneously. In the case of the passive after-flow, one fan must provide both ventilation and after-flow. The active after-flow relieves the main fan through the plug-in fan in the after-flow opening.
The application possibilities of the AKE
The AKE 100 is sufficient for rooms up to 30 sqm. With the larger variant AKE 150 rooms up to 70 sqm can be ventilated and dehumidified. In addition to cellars, the system can also be used for automatic ventilation of garages, laundry rooms, utility rooms and smaller warehouses. Due to the very low effort, the system is not only suitable for new buildings, but can also be retrofitted without problems in existing buildings.
