Air Science introduces its Purair ECO line of energy-saving ductless fume hoods designed for both chemical and particulate protection over a broad range of laboratory applications. The development of Purair ECO is in response to an increasing worldwide demand for safe, cost-effective, and energy-efficient ductless containment cabinets that minimize stress on facility HVAC systems without compromising protection for personnel and the environment. The Purair ECO 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 based on an industry-wide, non-proprietary ASHRAE-compliant protocol for green building management. The Purair ECO is available in five standard sizes from 30 inches to 69 inches wide.
