Nanofilter F7 for supply air filtration is an advanced air filtration solution that can capture up to 70% of fine dust. This filter uses innovative nanofiber technology to ensure high filtration efficiency and a long service life. Thanks to the multilayer structure of the filter medium and the use of nanofibers, this filter has a low pressure drop and the ability to capture large amounts of dust before it becomes clogged. It also offers more reliable filter quality than classic synthetic filters, whose filtration performance decreases over time due to gradual electrostatic discharge. In terms of filtration capacity and durability, this nanofilter is a better option than the standard F7 filter in our range. The entire filter frame is fitted with a foam seal to ensure maximum tightness of the filter in the ventilation unit.

Advantages of a nanofilter over a standard synthetic filter:
• Advanced filtration: Thanks to nanotechnology, fine particles are captured more effectively than with conventional synthetic filters.
• Lower pressure drop: Despite high filtration efficiency, nanofiber media can keep airflow resistance low.
• Longer service life: Thanks to its advanced design, the nanofilter has a longer service life and needs to be replaced less often.
• Higher efficiency: Delivers consistently high filtration efficiency thanks to its mechanical filtration principle.

The key features of the Safeluft filter:
• Solid frame, moisture-resistant and mold-resistant.
• MiniPleat filter media made in Germany with fine pleating.
• A filter surface area many times larger compared with pleated filters (Z-Line).
• Low pressure drop and longer service life.

This filter is intended for single use and cannot be rinsed with water or chemically cleaned. A replacement interval of 2–3 times per year is recommended (depending on incoming air quality).
