WFB fa'apipi'i-fa'aitiitia ta'avale-pulea & fa'apolokalame fa'amua pamu fa'aogaina "so'ota'i" masini fa'amaufa'ailoga centrifugal multidimensional, e leai se fa'alavelave mai le tamo'e, fa'avevela.pa'u ma liki.Pe a faatusatusa i oloa faapena, o lona soifua tautua e mafai ona faaumiumi tele ona o le aunoa ma le attrition ma abrasion o masini faamaufaailoga i le taimi o le faagaoioiga.
O lenei pamu ua tuʻuina atu i ai galuega eseese e pei o le vevela, mamafa, attrition teteʻe ma tasi tafega diversion mo le olaga lava ia lava, priming.Being faatuatuaina le tagata lava ia priming faatinoga, e faʻaaogaina faʻapitoa eletise eletise pulea valve e faʻaalia ai tulaga lelei e pei o le faʻatuatuaina faʻagaioiga, faigofie dis-assembly ma fa'apipi'i.
O lenei pamu e faia i mea eseese e pei o le u'amea u'amea, polypropylene fa'amalosia ma le uamea lafo, ma isi mea talafeagai mo taimi eseese.I le taimi nei, e pei ona manaʻomia e tagata faʻaoga, matou te mamanuina i latou i le tele o ituaiga e pei o quadrate, conical ma SO i luga mo faʻapipiʻi eseese modes.Explosion-proof type ma fafo ituaiga e mafai ona talafeagai mo taimi e mu, pa, timu, puao ma susu.Go-cart movable e mafai fo'i ona ave le pamu i so'o se pou faigaluega e te mana'omia.
