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

Advantages of a nanofilter compared to a synthetic standard 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 lifespan: Thanks to its advanced design, the nanofilter has a longer lifespan and needs to be replaced less frequently.
• Higher efficiency: Provides consistently high filtration efficiency due to the mechanical filtering principle.

The main features of the Safeluft filter:
• Solid frame, moisture-resistant and mold-resistant.
• Filter medium MiniPleat with fine folding made in Germany.
• Filter area several times larger compared to pleated filters (Z-Line).
• Low pressure drop and longer lifespan.

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