The ability of the fans to operate with maximum efficiency is supported by the design of the fan bases. Bases consist of heavy and federated hand lay GRP segments. Segments are assembled at the facilities with bolts and nuts. The discharge part of the bases could be cylindrical or in the form of expanding upwards. However, in both alternatives down part of the base must be in an expanding form in order to ensure proper airflow inside the tower. The standard color is RAL5012, you need to specify your request for other options.
