GENERAL DESCRIPTION
The ducted axial fans of CCZ series are used for ducted installations requiring large airflow with relatively low pressure drop, like ventilation and cooling systems in industrial, naval, commercial, civil, energetic fields.
These fans are particularly easy to install and to maintain thanks to their compact size and the total absence of protruding parts. The motor-impeller groupsare perfectly speed controllable and ensure low noise running. The series consists of 6 different sizes with impeller diameter from 310 to 560mm.
The fans are suitable for conveying clean air with temperature from -25°C to +60°C.
CONSTRUCTION
• Short casing in steel sheet, with fixing flanges manufactured according to UNI ISO 6580-EU-ROVENT standard. Protected against atmospheric agents by epoxy paint.
• High quality aerofoil profiled impellers in mineral fibres reinforced techno polymer (310 to 400) and die cast a aluminum alloy (450 to 560). Blades are directly fixed to the motor
external rotor.
• Execution 5 (with impeller directly coupled to the motor) and airflow from motor to impeller.
• External rotor motors with built-in thermal protection, double speed three-phase and
single-phase, speed adjustable. Connection box on the casing (up to model 400) and on
the motor (models 450 to 560).
ACCESSORIES
• Flat protection guard (CCr)
