Abstract:

A smoker's booth, for use within an enclosed area, including sidewalls having a door providing access to a single user compartment, wherein the sidewalls define upper and lower open ends. The lower end is closed by a base panel supporting the sidewalls, while the upper end is closed by a modular cap assembly, adapted for treating tobacco smoke-laden air drawn upwardly from the closed compartment. The modular cap assembly, which includes a closed space divided into a plurality of chambers, provides at least one plenum chamber and an electrical equipment chamber. An air treating unit is located in the plenum chamber, intermediate intake and return air vent openings communicating with the compartment. A blower draws tobacco smoke-laden air upwardly from the compartment, through the intake vent opening and plenum chamber, and returns only treated air to the compartment, via its return vent. As the compartment air is self contained, the booth obviates exchange of ambient air with tobacco smoke-laden air during its operation.
