QCL - axial fans ≤13000 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
• designed for clean air conveying in the -25 °C / +60 °C temperature range
• optimised intake cone combined with a bionic blade profile to reduce noise levels and increase aerodynamic and energy efficiency in accordance with EU Regulation 327/2011

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
• spiral impeller with sickle-shaped bionic blades in technopolymer (200-400) or cast aluminium alloy (450-710), directly connected to the engine rotor
• impeller directly coupled to the motor shaft
• air flow direction from the engine to the impeller
• intake protection made of steel according to EN ISO 12499
• models 200, 250, 630 and 710 with protection function and motor support. Models 310-560 with engine support bracket in epoxy powder-coated steel

ENGINE

• motor with external rotor, with built-in thermal protection
• single-phase motors are suitable for speed control, three-phase motors have two speeds (delta star YΔ)
• standard configuration "partly completed machines" according to Directive 2006/42/EC

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

• speed controller, please choose fan model you wish to purchase and contact us to find the right one

AIR CHARACTERISTICS
