Now we need to convert the cooling loads into volume flow costs but to try this we initially have to have to transform this to mass circulation level so we utilize the method:

Most swirl diffusers are made of galvanized steel but If you prefer them to get made of aluminium or plastic, you could possibly ship a ask for on the company. Some swirl diffusers are The mix of two supplies with your body made of galvanized steel along with the blades made of aluminium.
