A fan housing for allowing air to circulate through a fan having rotating fan blades while serving as a safety guard. The housing includes a circumferential wall located about the fan blades. The wall is shielded to a degree sufficient to inhibit the insertion of fingers or the like into the path of the blades adjacent to the blade path and relatively more open along other parts of the wall. The fan housing also includes front and rear safety panels. The fan housing has separable portions which may be pivotally opened and closed without the use of tools for allowing ready access to the fan unit within the fan housing for cleaning and maintenance.
