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

A control damper for a housing of an air-handling unit includes a rigid main body rotatable about a first rotational axis. A sealing element extends radially outwardly from a first side of the rigid main body. The sealing element is formed of a resilient material. The sealing element further includes a resilient lip extending outwardly from a distal end thereof. The lip has a first series of undulations formed in an outer edge thereof, wherein the undulations form a wave-shaped profile in the outer edge of the lip.

Saw tooth design for control damper

A control module for a heating, ventilating, and air conditioning system for a vehicle is disclosed, wherein a cost and a space requirement for the system are minimized and a control of temperature, mode, and volume of an air flow in a passenger compartment of the vehicle is optimized.
