ABSTRACT:
A system of casino tobacco smoke elimination based around a series of slot-like air intakes in which slot length is at least twice as great as slot height. In a preferred embodiment air velocity measured at the slot mouth should be about 1300 feet per minute, and a properly operating slot intake should provide a critical air capture velocity of about 50 feet per minute measured six inches from the slot mouth. A screen is preferably placed over the intake vents to prevent unwanted items from being pulled into the system. The suction system powering the slot-like intakes can end in a fan/filter unit that removes smoke pollutants and returns the cleaned air to the room, or the smoke laden air may be exhausted to the outside by the buildings air conditioning-ventilation system which also provides conditioned fresh air to replace the exhausted smoke. The configuration of the present system may be used in connection with numerous gaming devices, such as gaming tables, slot machines, video bars and nongaming structures such as restaurant booths and bars. When configured for slot machines, the intake vents are placed above and to the sides of the slot machines.
