Negative pressure glovebox having multifunctional air diverter

A negative pressure containment system including:

• A. A main chamber configured for an operator to manipulate materials;
• B. A diverter housing separated apart from said main chamber and including a diverter assembly, the diverter housing in fluid communication with said main chamber via a lateral flow air chase that is external to and extends from the diverter assembly on one end and is external to and terminates at said main chamber on an opposite end;
• and
• C. The diverter assembly within said diverter housing, said diverter assembly configured to direct a first gas to flow along a first path to said main chamber, and configured to direct said first gas to flow along a second path within said diverter housing, wherein said second path does not enter said main chamber;
• wherein the diverter assembly has an inside space and the first path travels through the inside space and is diverted through the lateral flow air chase and empties into the main chamber, and
• wherein the first gas flow may also flow along the second path via a bypass flow air chase that extends from the inside space through the diverter housing and terminates at a bypass filter compartment that is a part of the diverter housing, however is separated from the inside space of the diverter assembly.
