FAQ

Kitchen hood maintenance and cleaning
- To ensure the proper exhaust air flow from the kitchen hood, it should be maintained regularly.
- Clean the grease filter at least once a month, either by hand or in the dishwasher.
- Detach the grease filters from the quick-release latch.
- Clean also the frame and the area around the booster flap.
- Use a cleaner that is designed for cleaning powder-coated and plastic surfaces.
- Strong cleaners may alter the color of the grease filter; however, this does not affect the filter’s efficiency or its functionality.

How ofter should the AHU filters be replaced?
It is recommended to inspect and replace the filters of your air handling unit twice a year. However, the interval may vary depending on the environment. For example, in cities, filters may need to be replaced more frequently. High pollen levels and household pets can also affect the need for filter replacement. The appropriate interval can be determined by checking the conditions of the filter on a regular basis.

What is Mechanical Ventilation with Heat Recovery (MVHR)?
Mechanical ventilation with heat recovery (MVHR) is a ventilation system that removes used, moisture-laden, and polluted air from inside a building and replaces it with fresh outdoor air. A key feature of the system is heat recovery, which transfers the heat from the extracted air to the incoming supply air. This process is carried out by a heat recovery unit, which transfers thermal energy between airflows without mixing them.

What is Airfi Frost Pro System (AFPS™)?
AFPS is a frost protection system developed by Airfi that utilises artificial intelligence. It ensures that the heat recovery coil in the ventilation unit is defrosted only when necessary. Thanks to adaptive AI, the defrosting function operates for the exact duration required. A key feature is that the energy used for defrosting is sourced from the extract air that is leaving the building. The result is optimally functioning ventilation throughout the year and significant energy savings for households
