Duct Fan FR-DF
The FR-DF duct fan, also known as a radial fan, is intended for installation in ventilation ducts in facilities such as warehouses, shops, workshops, bathrooms, kitchens, detached houses and production spaces. It is equipped with an integrated mounting bracket and connection spigots, which significantly simplify and speed up installation.
About the product
FR-DF is a centrifugal duct fan designed for operation directly in ventilation ducts, in applications where an axial fan does not provide sufficient static pressure. The higher output pressure enables effective air transport through long and complex duct sections.
Airflow from 250 to 1,450 m³/h makes the unit suitable for both small spaces — bathrooms, kitchens, single-family homes — and for shops, workshops and production areas. The fan can operate in supply or exhaust mode.
The galvanised steel housing and IP44-rated motor with thermal protection up to 150°C ensure durability and safe operation. The integrated mounting bracket and connection stubs significantly simplify and speed up installation.
