BRF-V is a roof-mounted centrifugal fan with vertical discharge, designed for situations where air cannot be distributed horizontally. The housing, mounting plate, and fan wheels of models 225-400 are made of galvanized steel, while models 450-560 are made of aluminum, ensuring durability and corrosion resistance. The fans are equipped with an external rotor motor with enclosed construction, and aerodynamically curved blades guarantee quiet and uniform operation. The unit is designed for operation with air temperatures up to 40°C, and speed can be controlled using voltage regulators or an inverter. BRF-V is ideal for roof ventilation, bathroom and WC chimneys, and air refreshment systems, providing effective vertical air discharge with minimal noise levels.
