1.1 About EnviroSafe Fume Scrubbers 

Esco fume scrubbers (EFS) are optimally designed to provide effective air pollution control and laboratory personnel 
safety protection for ducted fume hoods. This is especially important laboratories and industries that use strong acid 
and alkali in their daily activities. 
 
EFS(s) are designed to be easily installed on top of Esco's Frontier Acela series fume hoods (EFA, EFF, EFI, EFQ, EFP). 
 
The chemical fumes exhausted by the fume hood(s) are filtered by the first layer of the demister layer (the green 
filter). This will ensure that the larger size chemical molecules trapped and wash away with the water. 
 
In the chamber, water or a suitable neutralizing liquid agent is constantly being sprayed at incoming fumes through a 
series of spray nozzles. The water molecules bond with the chemical fumes trapping them before they can be 
exhausted through the second demister layer. 
 
The scrubbing efficiency is further enhanced with the use of telleretes or scrubbing media. Telleretes are high 
efficiency packings that provide more surface area with higher liquid surface available for the gas and liquid phase. 
These packings are non-wetting and with high mass transfers, provide high absorption efficiency. 
 
A second layer demister trapped the water molecule in the chamber, minimizing water loss in the scrubber system 
and ensuring a clean, chemical free exhaust air. 
 
The water in the chamber is drained to the main tank, located in the fume hood’s base cabinet.
