A ventilating/sterilizing system for food-quality liquid storage tanks has a weatherproof overhead hood. Incoming air, drawn up into the hood is first filtered at the intake of an electric blower forcing the airflow through a main filter to be sterilized by ultraviolet radiation then heated for tank entry, where airflow drives out moisture and displaces air in the head region through a specially designed weather protective tank outlet vent with a removable cone-shaped dual-screen filter unit. A remote indicator light panel indicates normal operation and malfunctions. Stainless steel construction throughout minimizes deterioration and contamination. The main filter is enclosed in a housing mounted on a base unit containing the ultra-violet chamber, the heating chamber, and electrical components. The hood is hinged for intake filter access; similarly the blower assembly is hinged for main filter access for replacement or cleaning. Ultraviolet lamps in the base are accessible and replaceable from outside the unit without disassembly.
