 This system is designed to: a) reduce particulate entrapment in the fine particulate phase, b) ensure removal of particulate matter which is roughly similar to tobacco smoke as per literature on laser exhaust, and c) have sufficient residence time of the air in the carbon bed, while not increasing the overall dP of the filter system. This system is designed to: a) reduce particulate entrapment in the fine particulate phase, b) ensure removal of particulate matter which is roughly similar to tobacco smoke as per literature on laser exhaust, and c) have sufficient residence time of the air in the carbon bed, while not increasing the overall dP of the filter system.
  
-According to literature from the EPA (https://​www3.epa.gov/​ttn/​ecas/​docs/​cs3-1ch1.pdf) it is suggested to use a minimum bed depth of 3", along with face velocities of between 50-100 fpm to reduce streaming and breakthrough,​ while providing sufficient residence time. It should be noted that in this setup, the number of trays and flow area has been maximized in order to lower dP, and increase residence time. At the specified 350 cfm, and the 1/2 filter box area currently in use, the residence time in the current design is approximately 0.3s.+According to literature from the EPA ([[https://​www3.epa.gov/​ttn/​ecas/​docs/​cs3-1ch1.pdf|Download PDF]]) it is suggested to use a minimum bed depth of 3", along with face velocities of between 50-100 fpm to reduce streaming and breakthrough,​ while providing sufficient residence time.
