New and unused Blue e+ fan-and-filter units achieve maximum air throughput because they use pleated filters as standard. The wide-range input (100-240 V) supports worldwide use. Activation and monitoring via a Modbus interface supports exclusive features (automatic filter cleaning, filter maintenance display, emergency cooling function). The energy-efficient version with EC technology stands out for more than just its unique IoT capabilities. The Blue e+ fan-and-filter unit unlocks countless other advantages, from energy efficiency, to monitoring and sustainability, through to a higher air throughput (175 – 1,160 m³/h).
