Interruptions in breathing while sleeping, also known as sleep apnea, affects many people over the age of 40. The percentage of sufferers has reached double figures. And treatment is vital here given that, if left untreated, sleep apnea can lead to secondary conditions such as high blood pressure, heart failure, cardiac arrhythmia or even a heart attack.

The RV45 centrifugal fan assists breathing by ensuring a controlled supply of fresh air to the lungs. Further possible applications in medical technology include for example intensive ventilation, mobilization of mucus and mobile air filter technology, e.g. with respirators.

Lifesaver for sleepers

Dynamic air delivery for demanding applications: Fans used in the medical sector – for example in sleep apnea breathing devices – have to meet particularly high standards with regard to dynamics, smooth operation, reliability and compactness.


If sleep is constantly disrupted at night by sudden pauses in breathing (apnea), this may have serious risks to health. Air blowers can bypass or avoid this condition.

These systems and equipment use a range of blowers from ebm-papst. Low noise levels and a 100% constant pressure characteristic for the therapeutic pressure determined at the sleep lab are key to this application.

Durable, maintenance-free centrifugal blowers with outstanding control characteristics, aerodynamically optimized for use in respiration devices, are available in a wide variety of sizes and configurations.

Products from ebm-papst, a renowned engineering partner and manufacturer of blower solutions for respiration devices, have been used in numerous applications for years. To make sure that you too get a restful night's sleep. 


The breathing of the human.
We breathe in - we exhale. This process is repeated in an adult human about 20,000 times a day.
