E like me ke kumu kānana, hiki ke hoʻokaʻawale ʻia ka kānana ea i ke ʻano kānana, ke ʻano centrifugal, ke ʻano ʻauʻau ʻaila a me ke ʻano hui. ʻO nā kānana ea maʻamau i hoʻohana ʻia i loko o ka mīkini ka mea nui i loko o ka inertia aila ʻauʻau wai kānana, pepa kānana ea maloʻo, polyurethane kānana mea kānana ea a pēlā aku. Inertia aila ʻauʻau ʻano ea kānana ua hele i loko o ka inertia type kānana, aila ʻauʻau ʻano kānana, kānana ʻano kānana ʻekolu kānana, ʻo nā ʻano ʻelua hope loa o ka kānana ea ma o ka kānana ʻano kānana ʻano kānana. Inertia aila ʻauʻau ʻano ea kānana i nā pono o ka haʻahaʻa intake kū'ē, hiki ke hoʻololi i ka lepo a me ke one hana kaiapuni, lōʻihi lawelawe ola, etc., ma mua i hoʻohana 'ia i loko o nā 'ano like 'ole o nā kaʻa, tractor engines. Eia nō naʻe, ʻo kēia ʻano kānana ea he haʻahaʻa kānana kānana, nui ke kaumaha, kiʻekiʻe ke kumukūʻai a me ka mālama pono ʻole, a ua hoʻopau ʻia i ka mīkini kaʻa. Hana ʻia ka mea kānana o ka pepa kānana ea maloʻo me ka pepa kānana microporous i mālama ʻia e ka resin. ʻO ka pepa kānana he porous, wehe, pelu, loaʻa kekahi ikaika mechanical a me ke kū'ēʻana i ka wai, a loaʻa iā ia nā mea maikaʻi o ka pono kānana kiʻekiʻe, keʻano maʻalahi, ke kaumaha māmā, ke kumu kūʻai haʻahaʻa, ka mālama kūpono, a me nā mea'ē aʻe. i kēia manawa. Hana ʻia ka mea kānana o ka kānana ea i ka polyurethane palupalu, porous a spongy, nona ka mana adsorption ikaika. ʻO kēia kānana ea ka maikaʻi o ka kānana ea maloʻo pepa, akā he haʻahaʻa ka ikaika mechanical a hoʻohana nui ʻia i nā mīkini kaʻa. ʻO nā hemahema o nā kānana ea ʻelua i ʻoi aku ka pōkole o ke ola lawelawe a me ka hana hilinaʻi ʻole ma lalo o nā kūlana kūlohelohe koʻikoʻi.
