Ultravation® BioGardUV™ Upper Room Germicidal UV Air Disinfection

Safe and effective ultraviolet air disinfection for occupied spaces.

Ultravation® BioGardUV™ germicidal ultraviolet air disinfection destroys airborne pathogens by exposing the upper regions of a room to germicidal UV light. Since air naturally circulates in any room due to convection, air that is warmed in the lower part of a room (from respiration and other sources) continually rises where it will be exposed to UV light, which kills airborne bacteria and viruses in seconds. Since the UV light field is restricted to areas above seven feet, the room is safe for occupancy while the air is continuously disinfected.

Silent, natural convection operation: The FS-22 and FS-33 models disinfect the air as it naturally circulates in the room through convection. Convection occurs when rising warmed air from activity in the lower parts of the room from respiration, and other sources carry pathogens into the disinfection zone above. The disinfected air cools and falls back to the lower regions. Available with 22″ or 33″ UV lamp lengths.

Models with a circulation fan and air ionization: The FS-22F and FS-33F models include a quiet (30db) fan that accelerates the airflow and directs it past the UV lamp at 67 cfm. This also creates airflow across the upper part of the room where disinfection continues. These models include an air ionization system that freshens the air, forces air-suspended micro-particulates to collect into heavier groups that fall to the floor where they can be removed in normal cleaning or are big enough to be caught in filtration. Ionization also affects pathogens, contributing to air disinfection.   Available with 22″ or 33″ UV lamp lengths.

Ceiling mount models install flush-to-ceiling or with optional pendents. Ceiling mount models create an extended disinfection zone to the front and to the rear. Available in convection-only and fan/ionization models

Important: The 7-foot minimum installation height requirement (measured from the bottom of the unit) must be observed to assure the safety of the occupants.
