Ductless Fume Hood, Steel, 30" W x 53" H

The Purair Advanced Series ductless fume hoods are a series of high efficiency products designed to protect the user and the environment from hazardous vapors generated on the work surface. At the heart of the Purair fume hood product line is the innovative Air Science Multiplex Filtration Technology. <br /> <br />Included are: <br /> <br />Analog air velocity meter in the field of vision of the user provides independent backup to the electronic airflow alarm. <br /> <br />Double Hinged Self Locking Front Sash: When closed, the cabinet sash protects the operator with 100 FPM airflow. <br /> <br />Electronic controls and displays include switches for the blower and lights, an electronic hour counter and low airflow alarm,. <br /> <br />Steel Support Frame: The chemical resistant epoxy coated steel frame adds mechanical strength. <br /> <br />The pre-filter can be changed while the unit is operating to prevent operator exposure to chemical vapors. <br /> <br />Electrostatic Pre-Filter: The A 99.5% effective electrostatic pre-filter is accessible from inside the chamber to contain the release of any particulates that it traps. <br /> <br />Electrical cords and cables are safely routed into the cabinet through ports on the back and side walls <br /> <br />A filtered air sampling port allows manual filter monitoring. <br /> <br />A continuous air velocity monitoring system alerts the operator upon unacceptable values. <br /> <br />Dynamic Filtration Chamber: The dynamic filter chamber prevents any possible leakage of contaminated air by pressurizing the fan plenum (positive air) and depressuring the filter compartment (negative air). <br /> <br />Filter Door Key: Filter access keys prevent unauthorized removal or accidental exposure to dirty filters. <br /> <br /> <br /> <br />Sold separately is one required main filters (ASTM-001, ASTM-013, ASTM-015, ASTM-030, ASTM-200, or ASTM-100 depending on application)
