Laboratory Fume Hood Is Witnessing Wide Adoption In Laboratories To Provide Protection Against Toxic Fumes, Vapors, And Dust

Laboratory Fume Hood


 A laboratory fume hood, also known as positive air pressure (PAIP) hood, is a kind of local ventilation system which is designed mainly to control airborne exposure to toxic or harmful fumes, vapors, or particles in the air. It works by absorbing foul odors and gases in the air, thus eliminating these from the working area. This is used for many industrial applications in the food and pharmaceutical industries, cleaning facilities, healthcare facilities, and many more.

There are several reasons why a laboratory fume hood is used in the industry. One is its cost-efficiency, as it consumes a low amount of energy to maintain. It also has the capacity to increase air quality throughout the facility and prevent the occurrence of allergy attacks in sensitive people. Furthermore, the exhaust volume can be regulated to provide protection to those with respiratory conditions such as asthma. The way a laboratory fume hood functions differs from traditional ventilators in several ways. It utilizes two different types of filtration technology to remove contaminants from the air in a room. The first uses face velocity filtration and the second uses a sash opening exhaust system.

Most common of all was hoods, face velocity filtration uses a series of filters that push air through a fine strainer. The strainer has tiny holes in it, which allows air to pass through slowly. As the air passes through the filters, it is cleaned and collected in the collection tank. In this way, it prevents the escape of airborne particulates and bacteria, resulting in energy savings and improved air quality. Another option for using a laboratory fume hood in the work surface of a medical laboratory is to use ductless fume hoods. Recently, in May 2019, HEMCO Corporation, a U.S.-based company, launched a new UniFlow LE AirStream Fume Hood, which is available in 3’, 4’, 5’, 6’, and 8’ widths.
