Wall-Mounted Extractor Fan FR-BS
The FR-BS wall-mounted extractor fan has been designed to provide effective air circulation in production halls, warehouses, workshops and other industrial spaces. The axial fan housing is equipped with a square mounting plate for installation in a dedicated wall opening.
About the product
FR-BS is a robust axial fan designed for intensive, long-term operation in demanding industrial conditions. The entire construction — from the square housing to the impeller blades — is made of powder-coated steel, providing resistance to mechanical damage and corrosion.
A wide airflow range, from 780 to 20,000 m³/h, allows the unit to be matched to production halls, warehouses, workshops and large-area facilities. The drive is a proven AC induction motor with IP54 protection rating, compatible with controllers and voltage regulators.
Despite the high airflow, the fan operates quietly — noise levels start from 52 dB and power consumption from just 55 W. Wall-opening installation is straightforward and quick, and an optional gravity shutter protects against backflow and external factors.
