F4-72 nau'in gilashin karfe centrifugal ventilator ne mai amfani da gilashin karfe hadaddun kayan dangane da ƙarfe 4-72 nau'in ventilation sigogi. Wannan jerin fan iya jigilar da lalata gas dauke da acid-alkali abubuwa da sinadarai abubuwa. Gas da aka jigilar ba a yarda da dauke da m abubuwa, dauke da ƙura da kuma wuya granules ≤150mg / m3, gas temperature ≤60 ℃, dangane zafi ≤100%. Wannan jerin fan yana da high karfi, haske nauyi, ba sauki tsufa, mai kyau lalata juriya, low amo, aiki m da sauransu halaye. Yana da mafi m generic irin lalacewa iska. Wannan jerin fan yadu ake amfani da su a sinadarai, electroplating, oxidation, wutar lantarki tashoshi, dakunan gwaje-gwaje, waya allon, muhalli kare kayan aiki, da sauransu wurare dauke da lalata gas. Yana da kyau a yi amfani da shi.

BF4-72 nau'in gilashin karfe fashewa-resistant centrifugal iska ne da aka yi da EXdI ko EXdII Class A, B-Class fashewa-resistant keɓaɓɓen injin daidai da abokin ciniki amfani da yanayin. Za a iya jigilar da mai ƙonewa, mai fashewa gas da ke ƙunshe da methane, ethane, propane, styrene, methane, diphenyl, carbon monoxide, acetic acid, kerosene, man fetur, furan da sauransu. Its aiki sigogi da shigarwa girma daidai da F4-72 irin gilashi centrifugal iska. (B) F4-72 (C-irin) irin gilashi karfe centrifugal ventilator ne wheel amfani da ruwa sanyaya wurin zama ko man fetur sanyaya wurin zama longitudinal kusurwa band da inji. Amfanin shi ne rage lalata mota, rage sauri, rage mota kaya da sauran rawar, don haka kara iska aiki rayuwa.
