• QC: asynchronous three-phase or single-phase motors according to international standards IEC 600034, IEC 60072, EMC 2004/108/CE, LVD 2006/95/CE, CE marked, IP 55, class F.
• QC 200/250: fitted with shielded poles motors, class B.
• QC-ATX: asynchronous three-phase motors or single-phase II2G,II2D,II2GD according to international standards IEC 60034, IEC 60072, IEC 60079 and/or IEC61241, EMC 2004/108/ CE, LVD 2006/95/CE, with Atex certification, CE marked, IP55/IP 65, class F. All suitable to S1 service (continuous working at constant load).

The fans of the QC series are suitable for the ventilation, with wall or panel, in residential, commercial and industrial buildings. The series consists of 10 models with impeller diameter from 200 to 700 mm. The use of the QC series is foreseen for clean air in the temperature range -10°C +50°C.
The optimized inlet cone reduces noise level and increases the efficiency.
