Air Science, Fort Myers, Fla, has released the Purair Eco line of energy-saving ductless fume hoods designed for both chemical and particulate protection over a broad range of applications. The hoods were developed to minimize stress on facility heating, ventilating, and air conditioning systems without compromising protection for personnel and the environment. The line is available with a choice of controllers, including the company’s new EcoAir touchpad control with color display interface. An optional BACnet network interface connects all cabinet control, monitoring, and alarm functions to an open-source facility monitoring system. The system is compliant with the American Society of Heating, Refrigerating, and Air Conditioning Engineers protocol for green building management. The line is available in five standard sizes from 30 inches wide to 69 inches wide. For more information, visit Air Science.
