The Prima Klima PK250-L1 is highly efficient inline duct fan equipped with an ebm-papst RadiCal centrifugal motor with backward curved blades which has been optimally adapted to the housing. The entire housing is made of high impact resistant, flame proof polyamide (nylon). Maintenance free long lasting ball bearings contribute to especially smooth running of the motor. The control system, the connections and the capacitor are fully integrated into the housing. With the use of the supplied mounting bracket the fan can be easily and safely attached to the wall or ceiling in any position.The fan can be further controlled via a speed controller (Purchased seperately) this can then be used to slow the amount of air moved.
Centrifugal fans are a mechanical device for moving air. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction these fans increase the speed and volume of an air stream with the rotating impellers.
Centrifugal fans use the kinetic energy of the impellers to increase the volume of the air stream, which in turn moves against the resistance caused by ducts, dampers and other components. Centrifugal fans displace air radially. They are sturdy, quiet, reliable, and capable of operating over a wide range of conditions.
Centrifugal fans are constant-displacement or constant-volume devices, meaning that, at a constant fan speed, a centrifugal fan moves a relatively constant volume of air rather than a constant mass. This means that the air velocity in a system is fixed even though the mass flow rate through the fan is not. Centrifugal fans are not positive displacement devices and centrifugal fans have certain advantages and disadvantages when contrasted with positive-displacement blowers, Centrifugal fans are more efficient, whereas positive-displacement blowers may have a lower capital cost.
The Centrifugal fan is one of the most widely used fans. Centrifugal fans are by far the most prevalent type of fan used in the HVAC industry today. They are used in transporting gas or materials and in ventilation systems for buildings and vehicles. They are also well-suited for industrial processes and air pollution control systems.
