摘要

In various implementations, a fan system may include a housing and a fan. The fan may reside in an orifice of the housing. The fan system may include a grate disposed proximate a top surface and an ice deflector. The ice deflector may inhibit ice formation on portions of the housing, orifice, and/or fan residing in the orifice.
