DowVipengele vya kitambaa vya bidhaa ya FILMTEC ni muundo wa spiral roll, kwa kifupi muundo wa roll. Inajumuisha mfuko wa membrane ya leaf nyingi, kila mfuko wa membrane ya leaf inajumuisha membrane mbili za nyuma, maji ya bidhaa yaliyowekwa kati ya membrane mbili na maji ya kuingia ya turbulent grid kuwekwa juu ya uso wa membrane, mfuko huo wa membrane umefungwa kwa pande tatu na adhesive, na upande wa nne umefungwa kwenye bomba la kukusanya maji yenye shimo. Ikilinganishwa na muundo mwingine wa vipengele, kama vile aina ya bomba, sahani na fiber ya utupu, ina faida nyingi za usambazaji wa mtiririko wa maji, kiwango cha juu cha upinzani wa uchafuzi, gharama za chini za kubadilisha, bomba la nje ni rahisi, rahisi kusafisha matengenezo na matengenezo na uhuru wa kubuni, na kuwa aina ya muundo wa vipengele kuu vya membrane sasa.
