Ductless Fume Hoods Provide Chemical and Particulate Protection

摘要

The Purair ECO line consists of energy-efficient ductless containment cabinets that minimize stress on heating, ventilating, and air conditioning (HVAC) systems without compromising protection for personnel and the environment. They are available in five standard sizes and with a choice of controllers, includingthe company's new ECOair touchpad control with a color display interface. An optional BACnet network interface connects all cabinet control, monitoring, and alarm functions to an open-source facility-monitoring system based on industry-wide, nonproprietary ASHRAE-compliant protocols for green-building management. A proprietary filter-installation roller assembly simplifies filter replacement, assures proper gasket sealing, and eliminates bypass leakage during operation. Filter efficacy can be confirmed by an optional electronic gas-detection system with wide-spectrum internal chemical reference standards, including a metal oxide array for hydrocarbons and volatile organic compounds (VOCs), an acid array to detect acid vapors, and a front-mounted colorimetric gas-sampling port for manual testing. An ergonomic armrest helps improve user comfort and productivity.
