The Aironn R & D group continued their work without slowing down, making the compact stair pressurization fans they were working on shortly before ready for production. Stair pressurization fans are traditionally driven by an inverter located in an external panel. With the newly designed series, the inverter is available on the fan, even on the motor. This special design that stops cabling from the motor inside the fan to the pressurization board saves you from looking for an external panel. This series is suitable for working outdoors, thanks to its sound-insulated body structure, it works at low noise levels.
