    Duct Filters & Filter Inserts

    Discover Simas Filters' range of duct filters and insert filters, also known as elf hat filters, designed for installation in round ventilation ducts. The special design provides a filter area approximately four times larger than the cross-sectional area of the duct. This results in lower pressure loss and longer cleaning intervals compared to similar flat filters.

    Simas Filters also offers insert filters in various sizes, suitable for common ventilation systems such as Lindab. Choose Simas Filters for effective solutions for your ventilation needs.
