QCM - axial fans ≤17500 m³/h

• QCL - axial fans for residential, commercial and industrial buildings where compact dimensions, quiet operation and adjustable performance are required
• the series consists of 10 models with impeller diameters from 200 to 710 mm (models from 450 to 710 mm for the EU market only)
• designed for clean air conveying in the -25 °C / +50 °C temperature range
• optimised intake cone combined with a bionic blade profile to reduce noise levels and increase aerodynamic and energy efficiency

CONSTRUCTION

• Support frame made of pressed galvanised steel sheets, with radial inlet cone
• support frame of pressed steel sheet with radial intake cone, epoxy-coated for models 63 and 71
• impeller in technopolymer or cast aluminium alloy, directly connected to the engine rotor
• impeller directly coupled to the motor shaft, balanced according to ISO 1940
• direction of airflow from the impeller to the engine
• intake protection made of steel according to EN ISO 12499

ENGINE

• QCM 200 e 254: motors IP 44, class B
• QCM 252, 310/710: IEC 60034, IEC 60072, EMC 2014/30/EU and LVD 2014/35/EU, CE-marked motors, IP 55, Class F
• all models suitable for S1 operation (continuous operation under constant load)

ACCESSORIES

• S - gravity grilles, mounted outside. This prevents heat loss, wind, rain and birds. When the fan is running, the airflow opens the edges of the louvre and when the fan is switched off, the louvre closes by itself. The frame is made of steel sheets with an epoxy powder coating and the edges are made of technopolymer. The use of gravity grilles results in a slight reduction in performance

• D - adapter made of epoxy-painted steel sheet. It is required for the attachment of the fan when the width of the wall is less than dimension 'C' (the depth of the fan inlet). The frame shall be made of galvanised steel sheet (D63 and D71 epoxy powder-coated); the four corners shall be provided with 8 threaded inserts of galvanised steel sheet for the attachment of the fan on one side and of a gravity grille or protective mesh on the other

• R - impeller guard mesh, manufactured in accordance with UNI ISO 12499 and protected against atmospheric agents. This prevents accidental contact with the fan impeller. Frame and mesh made of epoxy-painted steel
