Dynair QCM Plate mounted axial fans

The QCM series of axial fans are suitable for applications  in residential, commercial and industrial buildings.  They can be mounted directly onto a wall, or to any adequately sized structure. The series consists of 10 models with impeller diameters ranging from 200 to 700 mm (models 450-710 are available only for extra-EU markets). The QCM series of fans are desgined for clean air in temperatures between -15°C and 50°C.  The aerodynamically optimized inlet cone reduces noise level, while increasing efficiency.
