Abstract
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.

- a housing formed with an orifice, the housing having a top surface:
- at least one flange formed on the top surface of the housing;
- a grate sized and configured to cover the orifice and disposed proximate the top surface over at least a portion of the at least one flange;
- an ice deflector disposed above the top surface of the housing and over at least a portion of the at least one flange;
- the ice deflector comprising:
- a base having a bottom surface and a sloped portion on a side opposite the bottom surface, and
- an annular protrusion defining an opening wherein the opening of the annular protrusion is over at least a portion of the orifice in the housing;
- wherein the sloped portion extends radially from the annular protrusion towards an exterior edge of the ice deflector;
- and
- wherein the grate is disposed between at least a portion of the housing and at least a portion of the ice deflector.
