FLOW RECTIFIER AND FAN ASSEMBLY HAVING A FLOW RECTIFIER

摘要

The invention relates to a flow rectifier for a flow inlet opening (7) of a fan assembly, comprising a grate structure (11) consisting of grate webs that cross each other, which grate webs bound a large number of grate openings (17) for sucking air in, wherein a preferably circular outlet opening bounded by an outlet-opening edge is provided for the outflow of air from the flow rectifier (8). According to the invention, the grate openings (17) bounded by the grate structure (11) are arranged around a closed central section (10) in a circumferential direction and radially outside of said central section, which central section is axially spaced apart from the outlet opening (15).
