The design of channel axial fans in a soundproof casing C - OZA - S
SOUNDPROOFED casing is made of galvanized steel sheet with heat and sound insulation of fire - retardant glass fiber 50 mm thick. Asynchronous motors with external rotor, equipped with internal thermal protection with automatic restart. The fan may be directly mounted in the duct. The use of rolling bearings in motors for long service life (40 000 hours). With speed control (fan performance in a single phase) or the inverter (three - phase fan performance) is carried out stepless speed control. The fan is powered via the integrated terminal box.
