I. Ductless Range Hood: Guardian of Fresh Kitchen Air
Ductless range hoods have become a must-have for modern kitchens with their unique design and efficient purification function. They not only effectively remove fumes, steam and odors, but also create a fresh and comfortable environment for the kitchen.
(I) Working Principle
The working principle of ductless range hoods involves a multi-layer filtration process. When air filled with cooking byproducts is sucked into the range hood, it passes through a series of filters. These filters work together to capture grease particles, smoke and odors. Among them, the internal circulation range hood mainly absorbs fumes with substances similar to activated carbon, which is suitable for kitchens with less fumes. Its exhaust refers to the separation of fumes, which uses various technologies such as filters to separate the fumes. The separated oil mostly flows into the oil collection cup, and the filter and oil collection cup can generally be seen outside.
Once the air is purified, it will be released into the kitchen, creating a cleaner environment. For example, Langxia smokeless duct fume purifier uses original fume adsorption technology and adsorption carbon deodorization technology. Through five-layer purification technology, the purified fume is directly discharged into the room, keeping the air in the kitchen clean and fresh.
