US 12,702,532 B2 · Systems and methods for producing a controlled operating environment

Abstract

An air handling and filtration/treatment system (whether portable of affixed) for the mitigation and management of airborne biological contaminants (either those pre-existing or those that may become generated) that includes a suspended air in-take assembly containing a removable filter; that includes a deflector having ducting leading to a housing assembly that includes a UV sanitizer, a fan assembly and controller; and includes an outflow assembly that includes ducting leading to a position able manifold having a plurality orifices. The manifold and deflector are laterally offset from the housing assembly and vertically aligned with each other. The manifold is positioned to encircle the bioaerosol source. When the system is operated, the fan assembly suctions air through the filter positioned at the duct inlet, through the UV sanitizer, and expels the treated air through the manifold orifices which are directed towards the deflector to create an air curtain and negative pressure environment which contains the newly generated bioaerosols directing them to the filter of the in-take assembly.

Dependent claims

An air handling and filtration/treatment system for use in performing dental procedures, comprising:

a) a housing assembly including a motorized fan assembly, a user interface and a controller;
b) an intake assembly including a removable filter, a first duct having a first end coupled to said housing assembly and a second end positioned laterally offset from said housing assembly, and a deflector positioned adjacent said second end, said first duct being in fluid communication with said fan assembly;
c) an outflow assembly including a second duct having a first end coupled to said housing assembly and a second end coupled to a manifold member, said manifold member being positioned vertically below said deflector and includes a plurality of orifices that direct airflow vertically towards the deflector, said second duct being in fluid communication with said fan assembly;
and,
said housing assembly further including an operable mode such that when said housing assembly is in said operable mode, operation of said motorized fan assembly causes the suction of air into said first duct second end and the expulsion of air through said second duct to thereby create a controlled environment positioned between said deflector and said manifold member whereby airflow emanating from said manifold is directed towards the deflector and is suctioned into said first duct second end.

a) a housing assembly including a motorized fan assembly, a user interface and a controller;
b) an intake assembly including a removable filter, a first duct having a first end coupled to said housing assembly and a second end positioned laterally offset from said housing assembly, and a deflector positioned adjacent said second end, said first duct being in fluid communication with said fan assembly;
c) an outflow assembly including a second duct having a first end coupled to said housing assembly and a second end coupled to a manifold member, said manifold member being positioned opposite said deflector and includes a plurality of orifices that direct airflow towards the deflector, said second duct being in fluid communication with said fan assembly;
and
said housing assembly further including an operable mode such that when said housing assembly is in said operable mode, operation of said motorized fan assembly causes the suction of air into said first duct second end and the expulsion of air through said second duct to thereby define a controlled environment positioned between said deflector and said manifold member whereby airflow emanating from said manifold is directed towards the deflector and is suctioned into said first duct second end.
