Air Science_Vent Box 300The Vent-Box ductless filtration system from Air Science, Fort Myers, Fla, is designed to protect laboratory personnel from chemical vapors found inside stand-alone chemical safety cabinets. The Vent-Box’s multiplex filtration system uses a prefilter and main filter to absorb, trap, and neutralize the target chemicals or particulate. A flexible hose connected to the cabinet draws in fumes and returns clean, filtered air to the laboratory, eliminating the need for external ducting and minimizing the loss of treated, conditioned air from the facility. The system’s modular design permits multiple configurations, and its compact size enables easy positioning on shallow safety cabinets. The Vent-Box meets or exceeds standards established by the Occupational Safety and Health Administration, the American National Standards Institute, and other international standards-setting bodies.
