Impellers

Vostermans Ventilation Inc delivers a wide range of impellers varying in diameter and materials (polypropylene, polypropylene with glass fiber, nylon or aluminum). Impellers are available in different impellers systems with different blade profiles.

 

Impeller systems

There are three different systems:

 

  • C-System: This system consists of a series of plastic hubs whereby the base of the blade has a flat side. The blade is manufactured with a fixed blade angle (25° - 45°). This means that the angle cannot be adjusted by the customer. The maximum torque strength of this system is less than the other systems.

  • K-System: In this system, the hub and blade are manufactured with 2 notches. During assembly of the blades in the hub, an adjusting ring (positioning ring) is placed between the hub and the blade, which determines the blade angle. These positioning rings can be supplied from 25° - 45°. The advantage is that only one blade type has to be kept in stock, which can supply every required angle with different positioning rings.

  • G-System: This system has the same characteristics as the K-system, but the G-system has a larger base, which permits a higher torque strength.
