Abstract:
A work station comprising:a base; a top cabinet; a support extending from said base and supporting said top cabinet, an air flow channel through which air may flow being defined through said support and partially through said base and said top cabinet; a work surface disposed on and forming a top to said base and having perforations along at least a portion thereof; a pressure inducing assembly located in said base for causing air to move through said air flow channel; and a controller for detecting an air flow parameter in said work station and connected to said pressure inducing assembly for automatically controlling said pressure inducing assembly based on said detected air flow parameter, said controller comprising: an air flow detector located in said air flow channel; a microprocessor connected to said air flow detector for receiving a signal therefrom and for converting said received signal to a digital pulse signal; and a motor control circuit connected to said microprocessor for receiving said digital pulse signal therefrom, said motor control circuit being connected to said pressure inducing assembly for providing a signal thereto to control the movement of air through said air flow channel.
