Zentrifugallüfter

A Zentrifugallüfter, also known as a centrifugal fan or blower, is a mechanical device designed to move air or other gases. It operates by using a rotating impeller to impart kinetic energy to the fluid, which is then directed outwards by centrifugal force. This process increases the pressure and velocity of the air, enabling it to be pushed through a duct system or into an open space.

The main components of a Zentrifugallüfter include a housing or casing, an impeller with blades, and a motor that drives the impeller's rotation. The air enters the fan axially, is accelerated by the rotating impeller, and then exits radially. The design of the impeller blades, such as forward-curved, backward-curved, or radial, influences the fan's performance characteristics, including airflow volume, pressure, and efficiency.

Zentrifugallüfter are widely used in various applications due to their ability to handle higher pressures compared to axial fans. Common uses include ventilation systems in buildings, industrial processes like material conveying and drying, HVAC (heating, ventilation, and air conditioning) systems, dust collection, and cooling of electronic equipment. They are chosen for their robustness, reliability, and suitability for moving air against resistance.
