Benchi yowongoka ya mpweya imatenga mawonekedwe akuyenda kwa mpweya mu njira yoyeretsera yoyenda yanjira imodzi, yomwe imaphatikiza fan yotsika phokoso ya centrifugal, static pressure kesi ndi fyuluta yogwira ntchito kwambiri mugawo limodzi.Mankhwalawa amatha kutengera benchi yolekanitsa kuti achepetse kukhudzidwa ndi kugwedezeka. Ndi mtundu wa zida zoyeretsera mpweya zomwe zimapereka kusinthasintha kwakukulu kwa chilengedwe cham'deralo choyera kwambiri. ndi kuonjezera mlingo wa zinthu zomalizidwa.
Mawonekedwe:
·Mlingo wa ukhondo CLASS 10 umagwirizana ndi muyezo wapadziko lonse wa ISO1466-1.
· Dongosolo lotsitsa phokoso lotsika lomwe lili ndi mpweya wosinthika limatengedwa kuti litsimikizire kuti liwiro la mpweya pamalo ogwirira ntchito nthawi zonse limakhala labwino.
· Thupi lamilandu limapangidwa ndi mbale yachitsulo yokhala ndi zokutira zamagetsi ndi ntchito.
