A blower unit for a suction device has a blower, which is embodied to effect a suction-air flow along a flow direction running from the suction side to the exhaust-air side of the blower unit during operation. The blower unit furthermore has a blower capsule in which the blower is arranged, and a suction-side bearing and an exhaust-air-side bearing for supporting the blower on the inner side of the blower capsule. In addition, the blower unit contains a protective element arranged on the suction-side bearing, which is embodied to be flowed through by the suction-air flow and to provide contact protection for the blower. The protective element is arranged on the suction-side bearing in such a way that the protective element is at a distance from the inner side of the blower capsule when the blower is in operation.
