Abstract
Ventilator apparatus to remove foul air and objectionable odors from a toilet comprising a vent duct manifold molded into the rear portion of the toilet bowl rim and communicating with a laterally extending coupling. The coupling communicates with a vent stack of the sewer in order to vent the manifold. The vent stack communicates with a blower which draws foul air out of the toilet bowl and discharges the air to atmosphere. The intake opening of the vent duct is positioned to prevent entry of water thereinto by a lip extending downwardly on the front edge of the vent duct.
