AFH Series
Comet Fans AFH Fan Series for Power and Energy Applications
The Comet Fans AFH series industrial axial fans are designed to ensure maximum reliability in the ventilation and cooling of infrastructure dedicated to the production and distribution of electrical power. These devices are ideally suited for use in transformer rooms, electrical substations, motor cooling systems and auxiliary systems in conventional power plants and wind farms.
Their construction configuration, developed on the basis of rigorous power sector specifications, ensures high performance even under the most demanding conditions: dusty environments, significant thermal variations and the presence of potentially corrosive substances. The use of resistant materials and attention to safety standards ensure operational continuity of the plant and reduce the risk of downtime.
The advanced blade aerodynamics minimise energy consumption, optimising heat exchange and air quality throughout technical rooms and conversion equipment.
The AFH range includes multiple solutions, with motors configurable for different ventilation requirements, and offers special versions for both indoor and outdoor installation.
Thanks to the use of lightweight alloys and composite materials, the blades withstand atmospheric agents over the long term and require reduced maintenance.
The performance of the AFH series makes it possible to protect equipment and maintain ideal ambient conditions for reliable, continuous processes, maximising plant efficiency.
