ABSTRACT:
A high efficiency ventilation system for removing contaminants from an area used in combination with an air conditioner or an environmental monitoring system. The system includes a fan unit and filter unit. The filter unit has two filters, a prefilter and a HEPA filter, each of which has its static pressure monitored by a separate gauge. The static pressure of the fan used in the fan unit is monitored by a third gauge. Thus, it is possible to determine which of two filters needs replacement and troubleshooting can be performed much faster and more efficiently. The air conditioner is coupled to the output of the fan so as to condition the air discharged from the ventilation system and pass the air back into the work area. The environmental monitoring unit may instead be coupled to the output of the fan so as to monitor contaminants that remain in the ventilated air.
