Funding<\/h2>\n\n\n
\n
\n\n
\n \n \n Are the devices generally eligible for funding? If so, through which institutions? What requirements are placed on funding for decentralised ventilation systems and how high is the funding amount? <\/span>\n <\/span>\n <\/button>\n <\/div>\n\n \n \n
\n
\n\n

Our decentralised systems with heat recovery are subsidised by the nationwide development bank KfW. You can find more information here: New build<\/a> or Renovation<\/a> <\/p>\n\n\n\n

For commercial customers<\/strong>, BAFA promotes ventilation systems with 35-45% in conjunction with an energy-efficient heat pump. You can find more information here<\/a>. <\/p>\n\n\n\n

In addition, individual funding programmes apply to federal states, cities and municipalities<\/strong>, which you can find on the funding map on our website.<\/p>\n\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n<\/div>\n<\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n\n \n<\/div>

Advantages & differences of getAir\u00ae systems<\/h2>\n\n\n
\n
\n\n
\n \n \n What distinguishes your system from other manufacturers of decentralised residential ventilation systems? <\/span>\n <\/span>\n <\/button>\n <\/div>\n\n \n \n
\n
\n\n

The SmartFan series systems achieve unique values in terms of sound insulation and efficiency. The SmartFan L Plus achieves a standard sound level difference of 60 dB, while the external air outlets (ALD) even reach 70 dB. The easyFan requires only 2.8 watts at maximum level, yet the volume flow in paired operation is 43 m\u00b3\/h. <\/p>\n\n\n\n

With the TOUCH control, our SmartFan features individual demand-based ventilation and extraction. Three different ventilation zones can be controlled with one control unit. This means that up to 3 different ventilation requirements in the house can be served at the same time. <\/p>\n\n\n\n

Via the SmartControl app, the devices can be easily controlled by voice command via Alexa or Google Assistant, and the control regulates the intensity of the air exchange fully automatically thanks to the air quality sensor.<\/p>\n\n\n\n

Features an optional pollen and fine dust filter (PM2.5), which can filter even the smallest pollutants from the outdoor and indoor air.<\/p>\n\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n\n\n

\n \n \n Where exactly is the difference between easyFan and SmartFan? <\/span>\n <\/span>\n <\/button>\n <\/div>\n\n \n \n
\n
\n\n

Our easyFan is a high-quality decentralised ventilation system with heat recovery that serves more than the basic ventilation requirements. In addition to the standard settings, such as “heat recovery” and “ventilation”, the PUSH control features an integrated humidity sensor as well as a filter change indicator. <\/p>\n\n\n\n

Our SmartFan is an intelligent ventilation system. In conjunction with the TOUCH or SmartControl unit and the sensor, the system features a variety of control options as well as automatic VOC, temperature and humidity regulation. Due to its various group settings, it is easy to set up different ventilation zones in your own flat\/house and adapt them individually. The SmartFan stands for very demand-oriented, comfortable ventilation. <\/p>\n\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n<\/div>\n<\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n\n \n<\/div>

Cleaning & Maintenance<\/h2>\n\n\n
\n
\n\n
\n \n \n How often do I need to change the filter? <\/span>\n <\/span>\n <\/button>\n <\/div>\n\n \n \n
\n
\n\n

We generally recommend replacing our dust, pollen and fine dust filters every \u00bd to 1 year, depending on the degree of soiling. If you have a filter change indicator, you will receive an automatic signal to follow. To ensure a particularly long service life for the filter, it should be briefly vacuumed every 3 months. You can easily access the dust filter by simply pulling out the inner cover. It can be replaced without tools. <\/p>\n\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n\n\n

\n \n \n How are ventilation systems maintained and cleaned? <\/span>\n <\/span>\n <\/button>\n <\/div>\n\n \n \n
\n
\n\n

Due to the tool-free assembly, the inner cover can simply be pulled out. To carry out a complete cleaning, the BUS connector is then removed from the fan and the fan unit is pulled out of the tube. The heat exchanger can then also be carefully pulled out. <\/p>\n\n\n\n

The tube can now be easily wiped out from the inside with a damp cloth.<\/p>\n\n\n\n

A simple replacement of the pre-filter can be carried out on the heat exchanger and the ceramic stone can be vacuumed.<\/p>\n\n\n\n

The fan unit is cleaned with a damp cloth.<\/p>\n\n\n\n

The dust filter in the inner cover can also be cleaned or replaced.<\/p>\n\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n<\/div>\n<\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n\n \n<\/div>
