Abstract (en)
[origin: CA2851745A1] A fan (1) that is to be used primarily in underground mining and tunnel construction has a tubular fan housing (2), the inner wall (5) of which has sound-conducting openings (24, 25) that are designed in a specific manner. Said sound-conducting openings (24, 25), which are generally annular, annularly leave enough surrounding material (23) in the segment (16) that supports the fan wheel (9) and the drive (10) in order to thus ensure the secure and precise arrangement of the two components. The inner wall (5) is omitted in the remaining region, said outer wall (4) and/or the coupling wall (3) as such being designed to compensate for the effect of the sound-conducting openings.
