Abstract: First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.

Abstract: A dual direction vacuum apparatus for creating vacuum and purging obstructions from a vacuum port of the apparatus. The apparatus provides a housing having an air passageway, wherein the air passageway has a first end and a second end. A vacuum pressure inlet is formed in the housing and is adaptable to receive pressurized air from a pressurized air source to create vacuum in the vacuum port and establish a vacuum mode. A purge pressure inlet is formed in the housing and adaptable to receive pressurized air from a pressurized air source to direct pressurized air toward the vacuum port to establish a purge mode and dislodge any obstructions from the vacuum port.

Abstract: A method of pressurization and evacuation of a system including during a pressurization phase; introducing a pressurized gas stream into the top valve, which is actuated to direct the pressurized gas stream into the bottom valve, wherein the bottom valve is actuated to direct the pressurized gas stream to the customer apparatus; and during a vacuum phase; introducing the pressurized gas stream into the top valve, which is actuated to direct the pressurized gas stream into the inlet port of the pressure inlet of the educator, thereby producing a low pressure condition in the suction inlet, introducing a customer gas stream into the bottom valve, which is actuated to direct the customer gas to exit the bottom valve, wherein the low pressure condition causes the customer gas stream to be directed to the educator suction inlet, wherein it mixes with the pressurized gas stream and exits the educator discharge outlet.
