Abstract
A negative pressure containment system is configured to run in lateral air flow mode or enhanced controlled environment mode, depending on the operator's needs. A diverter assembly facilitates switching between modes by directing air into alternative air chases. In the enhanced controlled environment mode there are two concurrent air paths that eventually converge, with one path being a bypass flow that creates negative pressure in the main chamber and another path being compressed air that feeds the main chamber. In this mode it is possible to precisely control the chamber environment.
Claims9
An air diverter system for use with a negative pressure containment system including:
- A. A diverter housing including a diverter inlet defining an air path into said diverter housing, the air path emptying into a diverter assembly, wherein the diverter assembly is separated apart from a bypass filters compartment by a wall that divides the diverter housing into discrete separate spaces housed within the diverter housing;
- B. A lateral flow air chase in fluid communication with said diverter housing, said lateral flow air chase for diverting air out of said diverter assembly and to a main chamber that forms a separate chamber than the diverter housing;
- C. A bypass flow air chase in fluid communication with said diverter housing, said bypass flow air chase for moving air from a different region of said diverter assembly than the lateral flow air chase, and to the bypass filters compartment;
- wherein the diverter assembly allows air flow through the lateral flow air chase and the bypass flow air chase, with the lateral flow air chase situated in a vertical alignment between the diverter assembly and the main chamber;
- and
- D. the bypass flow air chase extending horizontally along a lower side of the diverter housing and emptying into filters within the bypass filters compartment;
- E. A lateral flow main chamber outlet in fluid communication with the main chamber and the bypass filters compartment of the diverter housing, wherein air flow from the main chamber is directed to the bypass filters compartment and reenters the diverter housing.
