A centrifugal blower unit for motor vehicle air conditioning systems having a fan wheel () in a spiral housing (), wherein the spiral housing () corresponds to the shape of the fan wheel () and has a bell mouth region () and an axial intake opening (), wherein a diaphragm () is arranged at the bell mouth region () of the spiral housing (), being radially inward, whose diaphragm end region () bordering the intake opening () has at least one sharp edge.

Centrifugal blower unit

An air filter and fan device for a vehicle ventilation system is disclosed that, in direction of air flow, includes an air filter, an impeller, and a flow-off channel. A casing is provided that accommodates the impeller and the flow-off channel in an enclosing manner such that the impeller is established with double-suction, receiving air from the air filter from both a first side and a second side or the impeller.

Air filter and fan device for vehicle ventilation systems

A device for control of the air flow rates into the instrument panel air outlets of a vehicle heating or air conditioning unit is described that is provided with a casing, with damper doors for both instrument panel side air outlets in the casing parts and at least one damper door for the instrument panel central air outlet in the casing part, whereby the damper doors are pivotably supported on one common shaft. Exactly one closing position is assigned to the damper doors in the first casing part, whereas several closing positions are assigned to the damper door in the second casing part continuously over a pivoting range of the shaft, whereby the closing position of the damper doors is arranged in the pivoting range of the damper door. This device enables separation and independent control of the air flow rates.
