All Thoren Caging Systems use one of our three different style self-contained HEPA filtering unit. These Blower/Filter Modules can be mounted on top of a caging system or underneath. A third option is the free standing unit. All Blower/Filter Module are constructed of stainless steel and are readily attached to or detached from the caging system. Units are equipped with dampers on both supply and exhaust. They also provide either positive or negative pressures relative to the room. All units come with detachable electrics to make washing or autoclaving possible. The units have two separate HEPA filters which are 99.99% efficient. The supply module provides HEPA filtered air to the system and the exhaust module filters spent air from the unit. To extend the life of the HEPA filters, the unit is equipped with prefilters which are washable or autoclavable.
