Negative pressure fan, wotchedwansokutulutsa mpweyakapenampweya wabwino fan, ndi makina opangira makina omwe amachotsa mpweya wonyansa, chinyezi ndi fungo mu malo otsekedwa.Mafani otulutsa mpweya amatha kugwiritsidwa ntchito m'malo osiyanasiyana: minda yaziweto, nyumba zobiriwira, malo ochitirako ntchito zamakampani, ndi zina zambiri.
Pofuna kulola kuti ogwiritsa ntchito ambiri amvetsetse zatsatanetsatane komanso zitsanzo zakutaya mafani, Wopanga mafani a Nantong Yueneng amagawana zomwe amafanizira omwe amagwiritsidwa ntchito kwambiri ndi aliyense kuti muwafotokozere.
1.Onani chithunzi pamwambapa: chowotcha cha square exhaust: chogawidwa mumtundu wolemera wa nyundo ndi mtundu wokankhira-chikoka.Zakunja chimango zinthu zambiri malata mbale ndi 304 zitsulo zosapanga dzimbiri.Mawonekedwe ake ndi a square.Pali ukonde wotetezera kumbali yolowera mpweya komanso wotchinga fumbi kumbali ya utsi.Makhungu amvula, akhungu amawomberedwa mwachibadwa ndi mphepo panthawi yogwiritsidwa ntchito bwino, ndipo adzatseka pokhapokha mphamvu ikatha.Kwa mafani otulutsa nyundo olemera amtundu wa nyundo, m'nyengo yozizira kapena pamene mphamvu yazimitsidwa, zotsekera zimatha kutsegulidwa pogwiritsa ntchito chosinthira chamanja kuti mupeze mpweya wabwino komanso kuyatsa.
