Iyo aperture ye molecular sieve 5A inenge 5 angstroms, inonziwo calcium molecular sieve.Inogona kushandiswa mukumanikidza swing adsorption zviridzwa zveokisijeni-kugadzira uye hydrogen-kugadzira maindasitiri.
Nheyo yekushanda yemasefa emamorekuru inonyanya kuenderana nesaizi yepore yemamorekuru sieves, wIvo vanogona kushambadza mamorekuru egasi ane dhayamita yemamorekuru idiki pane saizi yepore.Iyo yakakura saizi yehukuru hwepore, iyo yakakura iyo adsorption kugona.Kukura kwepore kwakasiyana, uye zvinhu zvakasvibiswa uye zvakaparadzaniswa zvakasiyanawo.Kana inoshandiswa se desiccant, molecular sieve inogona kutora kusvika ku22% yehuremu hwayo muhunyoro.
