Parents, I'm glad to answer your question. Kitchen exhaust fan selection, first of all, in the indoor direct exhaust fume kitchen (i.e., exhaust port in the indoor wall), according to the size of the fumes to choose the kitchen exhaust fume fan. Secondly, for the smoke, and the smoke needs to go through the long pipeline, and the pipeline has a bending treatment of the kitchen, it is strongly recommended to use the exhaust fume fan, this is because the exhaust fume fan pressure than the axial fan, and the smoke does not go through the motor, the motor of the maintenance and cleaning is easier. Finally, it is recommended that kitchens with large amounts of grease and smoke use the above two options and use them for better results. I hope my answer can help you.
