Main characteristics:
- These devices are designed for air purification with a maximum dust content of 0.5 mg/m³.
- The air temperature range that can be supplied to the device is from -20℃ to +40℃. At a maximum air humidity of no more than 19 g/kg.
- These filters trap at least 70% of PM2.5 dust. F7 filters are characterized by a large filtration area, which reduces flow resistance and extends their service life.
Purpose:
The duct filter is designed to ensure the supply of high-quality air to various types of buildings: residential, commercial, public, and industrial.
The F7 DN200 duct filter is suitable for ventilation units: KNP 500 Perfect, KNV 400 Perfect, KNH 500 Perfect.
Construction:
Duct filters have an insulated housing, air filter, pressure relay to control the degree of filter contamination, mounting brackets, and inspection hatch. They should be installed in supply air ducts, avoiding areas with high dust levels. For example, rooms with plaster remnants or floor sanding.
Service life:
It is recommended to check F7 filters every 3 months and replace them every 6 months, regardless of their condition. The built-in pressure sensor monitors the pressure drop, and the system informs about the need to replace the filter.
