Ventilation cleaning · service
The fan is the heart of the air handling. A fan impeller covered in dust and fibres loses efficiency and runs harder, and you hear that in the noise level.
Back to ventilation cleaning
We clean the reachable fan components: the impeller, the blades, the housing and the suction side. For fans that are only accessible after dismantling, we advise a service visit by the manager or installer.
Belt-driven units are checked for belt wear and bearing condition. Those points are named, but only adjusted when that is explicitly part of the assignment.
You send a photo of the fan housing or of the technical room.
We assess the access, the fan type and the contamination.
Cleaning of the accessible components, with a report of the check.


These photographs are Basel's own field photos. They show the type of component and its visible condition; they are not intended as evidence of a specific assignment or location.
