Ko te mea powhiriwhiri tepu 3D DC he momo powhiriwhiri tepu DC me te mahi ahurei "te hau toru-ahu".Ko te tikanga ko te mea powhiriwhiri he mea hoahoa ki te hanga i nga tauira rerenga hau-toru ka taea te whakamatao i te waahi whanui atu i nga kaiwhaiwhai tuku iho.Engari ki te pupuhi i te hau ki te huarahi kotahi, ka hangaia e te 3D Wind Blow DC Desk Fan he tauira rerenga hau-maha, he oscillating poutū me te whakapae.Ka awhina tenei ki te tohatoha i te hau hauhautanga ki roto i te ruuma, ka pai ake te noho humarie me te hauhautanga mo nga kaiwhakamahi.I roto i te katoa, ko te 3D Wind DC Desk Fan he taputapu whakamahana kaha me te pai hei awhina i te rere o te hau me te whakaora i te rangi wera.
