A system includes an intake, an exhaust, and an adjustable directing member. The intake is for taking in air, the exhaust is for exhausting air, and the adjustable directing member is positioned for directing exhaust air toward the intake. Another aspect is a system that includes a source of polluted air and an air cleaning system. The air cleaning system includes an intake, an exhaust, and a directing member. The intake is for taking in polluted air and the exhaust is for exhausting air. The directing member is for directing air from the exhaust toward the intake to provide an air screen for keeping the polluted air in the vicinity of the intake.
A system for operating a replaceable appliance that may produce polluted air, comprising a recirculating ventilation system, wherein said recirculating ventilation system includes a structure having a base, an intake, and an exhaust, wherein said base includes a base duct section, wherein said base duct section is connected for bringing air taken in through said intake to said exhaust, wherein said base duct section has a first configuration and a second configuration, wherein when said base duct section is in said first configuration said base duct section includes a platform pan that acts as a top surface and encloses said base duct section from above, wherein when said base duct section is in said second configuration said platform pan is removed and said base duct section is open to an environment that is external to the system via an opening created by the absence of said platform pan, wherein enclosing and opening said base duct section with said platform pan allows said base duct section to go back and forth between said first configuration and said second configuration, wherein when said platform pan encloses said base duct section said platform pan is positioned for supporting the replaceable appliance on said base, wherein said exhaust is positioned in said base for exhausting air from said base duct section, and wherein when air is exhausted from said exhaust said exhausted air is drawn to said intake to provide an air curtain.
A system for operating a replaceable appliance that may produce polluted air, comprising a base, an intake, and an exhaust, wherein said base includes a base duct section, wherein said base duct section is connected for bringing air taken in through said intake to said exhaust, wherein said base duct section has a first configuration and a second configuration, wherein when said base duct section is in said first configuration said base duct section includes a platform pan that acts as a top surface and encloses said base duct section from above, wherein when said base duct section is in said second configuration said platform pan is removed and said base duct section is open to an environment that is external to the system via an opening created by the absence of said platform pan, wherein enclosing and opening said base duct section with said platform pan allows said base duct section to go back and forth between said first configuration and said second configuration, wherein when said platform pan encloses said base duct section said platform pan is positioned for supporting the replaceable appliance on said base, wherein said exhaust is defined by an edge of said base duct section and is positioned for exhausting air from said base duct section to said intake to provide an air curtain.
A system for operating a replaceable appliance that may produce polluted air, comprising a free standing recirculating ventilation system, wherein said free standing recirculating ventilation system includes a plurality of sides, a base, and an intake, wherein said base includes a base duct section and an exhaust along each of said plurality of sides, wherein said base duct section has a horizontally-disposed top surface positioned to directly contact a bottom of the replaceable appliance when the replaceable appliance sits on said base, wherein said intake is positioned to take in air, wherein said base duct section is connected for bringing air taken in through said intake to said exhaust, wherein said exhausted air is drawn to said intake to provide an air curtain, wherein said air curtain extends from said exhaust along each of said plurality of sides of said base to said intake, and wherein said air curtain extending along said plurality of sides traps the polluted air within said air curtain.
A system for use while operating a replaceable appliance that may produce polluted air, comprising a recirculating ventilation system, wherein said recirculating ventilation system includes a structure having a base, an intake and an exhaust, wherein said base includes a base duct section and said exhaust, wherein said base duct section has a horizontally-disposed top surface positioned to directly contact the replaceable appliance when the replaceable appliance sits on said base, wherein said intake is for taking in air, wherein said base duct section directs air taken in through said intake to said exhaust, wherein said exhaust includes a directing member for directing air exiting said exhaust toward said intake to provide an air curtain, wherein said directing member includes an adjusting handle disposed outside of a region enclosed by the air curtain configured for adjusting a direction of said air curtain toward said intake during operation of the replaceable appliance that generates polluted air.
