A ductless fume hood is a contained working space that uses powerful negative airflow to pull harmful fumes, vapors or particulate away<\/strong> from the operator\u2019s respiratory zone<\/em> and protects the operator and the environment<\/em> from exposure.<\/h2>\n

How does a Ductless Fume Hood work?<\/font><\/center><\/h2>\n<\/div>\n

 
\n\"Ductless<\/a>
\n <\/p>\n

\n\"Ductless<\/div>\n
\nAmbient Air is drawn into the hood and mixed with fumes, vapors or particulates emitted from the process.<\/div>\n
<\/div>\n
\n\"Ductless<\/div>\n
\nThe air within the hood is processed through a pre-filter where some particles are captured.<\/div>\n
<\/div>\n
\n\"Ductless<\/div>\n
\nAir is filtered through the main filter (HEPA, ULPA, ASHRAE, Activated Carbon or Specialty Blended).<\/div>\n
<\/div>\n
\n\"Ductless<\/div>\n
\nFiltered air is released back into the room eliminating the need for duct work.<\/div>\n<\/div>\n
