Inaliti yePolyester (i-PET, i-terylene ivakale) ivakale ilaphu lokucoca elingalukwanga elineempawu zokuqina okuphezulu, ukuxhathisa kwe-abrasion, ukuxhathisa okulungileyo kwe-asidi, ibakala lokutya, enye yezona zinto zinoqoqosho zokucoca ezisetyenziswa ngokubanzi kwizicelo zamashishini ezahlukeneyo zokuqokelela uthuli. ukusetyenziswa (ilaphu lokucoca uthuli lwemveliso yeengxowa zokucoca uthuli).
I-Zonel Filtech elona qela linamava nelinobuchule, inaliti yangoku yokuhlaba intambo edityaniswe nemathiriyeli ekrwada yodidi lokuqala yenza inaliti yepolyester ivakale ngelaphu lokucoca elivela kwiZonel elinokungena komoya okulinganayo kunye nobukhulu, amandla aphakamileyo okubamba, umphezulu ogudileyo kunye nokukhulula ngokulula. ikeyiki yothuli, yomelele.
Ngokweemeko ezahlukeneyo zokusebenza kunye nezicelo zokukhutshwa, ilaphu le-polyester lokucoca lingakhetha iindlela ezahlukeneyo zonyango, ezifana namanzi kunye ne-oyile yokugxotha, i-PTFE yokuxhoma ibhafu, i-PTFE inwebu elaminethiweyo, ubungqina bomlilo kunye nokunye ukwenzela ukuba wenze ezi zihluzo zokucoca ukuqokelela uthuli kunye. ukusebenza ngokugqibeleleyo kohluzo.
