The objective is always to use move air as efficiently as possible, whether in the tightest spaces, in large dimensions or under extreme ambient conditions. Thus ebm-papst radial impellers, centrifugal blowers and axial fans have a long history of successful use in bathroom ventilation, HVAC systems, façade ventilation, and roof fans. In these applications, ebm-papst fans move the required volume of air in residences, offices, and buildings. Intelligent control for single rooms is possible, as is bus connection of all systems, for example in multistory buildings. Thanks to their durability and high efficiency, and the energy savings this provides, our fans meet the need for a long-lasting pleasant climate at home and at work.
