Cleaning recirculated air system has air inlet in central region and air outlet in peripheral region of work region with fan downstream of cleaning device

摘要

A cleaning recirculated air system, contains: - a work region with an air inlet (12) and an air outlet (14); - a cleaning device (18) and a fan (20) which components are arranged over pipelines (16) so that the fan sucks in air through the air inlet which flows through the cleaning device and leaves the work region through the air outlet. The air inlet is located in a central region and the air outlet in a peripheral region of the work region. The fan is located downstream of the cleaning device. A pipeline leading from the air inlet to the cleaning device is located near a pipeline leading from the fan to the air outlet.
