Abstract
"CONJUNTO DIFUSOR". O conjunto difusor (10) da invenção inclui um primeiro e um segundo corpo difusor (23, 24) em comunicação fluida com um cano de distribuição de ar (14). O conjunto difusor (10) inclui ainda um suporte (16) que sustenta o primeiro corpo difusor (23) e o segundo corpo difusor (24). O suporte (16) está ligado ao cano de distribuição (14) por um rebite de núcleo oco (90). O fluido é forçado do cano de distribuição (14) através do rebite de núcleo oco (90) onde o fluido passa para dentro dos primeiro e segundo corpos difusores (23, 24). O fluido sai do primeiro corpo difusor (23) através de um primeiro meio difusor (35) e sai do segundo corpo difusor (24) através de um segundo meio de difusão (36). Os primeiro e segundo meios de difusão (35, 36) transforma o ar em bolhas finas que servem para facilitar o arejamento do fluido.
