Wahi a ke kumumanaʻo kānana, hiki ke hoʻokaʻawale ʻia ke kānana ea i ke ʻano kānana, ke ʻano centrifugal, ke ʻano ʻauʻau ʻaila a me ke ʻano hui. ʻO nā kānana ea i hoʻohana nui ʻia i loko o ka ʻenekini e komo pū me ke kānana ea ʻauʻau ʻaila inertia, ke kānana ea maloʻo pepa, ke kānana ea ʻāpana kānana polyurethane a pēlā aku. Ua hele ke kānana ea ʻauʻau ʻaila inertia ma o ke kānana ʻano inertia, ke kānana ʻano ʻauʻau ʻaila, ke kānana ʻano kānana ʻekolu, ʻo nā ʻano kānana ea ʻelua hope loa ma o ke kānana ʻano kānana ʻāpana kānana. Loaʻa i ke kānana ea ʻauʻau ʻaila inertia nā pono o ke kū'ē haʻahaʻa haʻahaʻa, hiki ke hoʻololi i ke kaiapuni hana lepo a me ke one, ke ola lawelawe lōʻihi, a pēlā aku, i hoʻohana mua ʻia i nā ʻano hoʻohālike o nā kaʻa, nā ʻenekini tractor. Eia nō naʻe, he haʻahaʻa ka pono o kēia ʻano kānana ea, ke kaumaha nui, ke kumukūʻai kiʻekiʻe a me ka mālama pono ʻole, a ua hoʻopau mālie ʻia i loko o ka ʻenekini kaʻa. Hana ʻia ka ʻāpana kānana o ke kānana ea maloʻo pepa me ka pepa kānana microporous i mālama ʻia e ka resin. He porous ka pepa kānana, he palupalu, he pelu ʻia, he ikaika mechanical kekahi a me ke kūpaʻa wai, a he mau pono o ka pono kānana kiʻekiʻe, ka hoʻonohonoho maʻalahi, ke kaumaha māmā, ke kumukūʻai haʻahaʻa, ka mālama pono ʻana, a pēlā aku. ʻO ia ka kānana ea kaʻa i hoʻohana nui ʻia i kēia manawa. Hana ʻia ka ʻāpana kānana o ka kānana ea me ka polyurethane palupalu, porous a me ka spongy, nona ka mana adsorption ikaika. Loaʻa i kēia kānana ea nā pono o ka kānana ea maloʻo pepa, akā he haʻahaʻa kona ikaika mechanical a hoʻohana nui ʻia i nā mīkini kaʻa. ʻO nā hemahema o nā kānana ea ʻelua hope loa, ʻo ia ka pōkole o ke ola lawelawe a me ka hana hilinaʻi ʻole ma lalo o nā kūlana kaiapuni ʻino.
