Filters are an integral part of ventilation systems. Their main task is to keep dust particles, dust, allergens, bacteria, viruses and other pollutants out of the air before they enter the room.
Circular duct filters are mounted directly on the ventilation duct. Their construction is usually a rectangular box with connections for a circular duct containing a filter cartridge inside. Thanks to this construction, we have easy access to the filter, which allows us to quickly assess the state of contamination and, if necessary, replace the filter. We can use filters of any filtration class, while keeping in mind the resistance they generate.
