Centrifugal fans
Centrifugal fans draw air axially and discharge it radially through the spiral casing, generating significantly higher static pressure than axial fans of similar power. The standard equipment for any ventilation system involving duct networks — offices, commercial spaces, medical facilities, industrial applications — where cumulative hydraulic resistances require high pressure to maintain the designed airflow.
Centrifugal fans operate quieter than axial fans at similar airflow rates. The range includes low-pressure models for light residential ventilation, medium-pressure for commercial systems, and high-pressure for pneumatic conveying and industrial processes.
How to choose: start with the required airflow and static pressure calculated across the complete duct run. Choose the pressure variant appropriate to the application.

Centrifugal fan DDM 12/12 E6G3702 1F 6P in BOX
Nicotra Gebhardt DDM 12/12 E6G3702 double-width double-inlet (DWDI) centrifugal fan, pre-mounted in acoustic plenum BOX enclosure.
External rotor motor (ERM) single-phase 6-pole — ~900 rpm at 50Hz versus ~1,400 rpm for 4-pole motors.
Lower speed means significantly reduced noise, lower energy consumption and quieter operation — the defining advantage over DDM 12/12 variants with 4-pole motors.
IP54, Class F insulation, integrated thermal protection, direct drive without belt.
BOX with polyurethane insulation, aluminium frame, removable side panel for rapid access to motor and impeller.
For AHU, plenums, commercial ventilation and acoustically sensitive spaces.
