Inaliti ye-Polyester (i-PET, i-terylene ezwakele) izwakale ngendwangu yokuhlunga engalukiwe enezici zamandla aphezulu aqinile, ukumelana ne-super abrasion, ukumelana ne-asidi enhle, izinga lokudla, enye yezinto zokuhlunga ezonga kakhulu ezisetshenziswa kakhulu ezimbonini ezihlukahlukene zokuqoqa uthuli. ukusetshenziswa (indwangu yokuhlunga uthuli yokukhiqiza izikhwama zokuhlunga uthuli).
I-Zonel Filtech eneqembu elinolwazi kakhulu futhi elinekhono, ungumnikazi wemigqa yesimanje yokubhoboza inaliti ehlanganiswe nezinto zokusetshenziswa zebanga lokuqala yenza inaliti ye-polyester izwakale isihlungi esivela ku-Zonel enokungena komoya okulinganayo nokuqina, amandla aqinile aphezulu, indawo ebushelelezi kanye nokukhulula kalula ikhekhe lothuli, eliqinile.
Ngokwezimo ezihlukene zokusebenza kanye nezicelo zokukhishwa, indwangu yokuhlunga i-polyester ingakhetha izindlela zokwelapha ezihlukahlukene zokuqeda, ezifana nokuxosha amanzi namafutha, ukugeza kwe-PTFE ukumiswa, ulwelwesi lwe-PTFE elamiwe, ubufakazi bomlilo nokunye ukuze wenze lezi zindwangu zokuhlunga ukuze ziqoqwe ngothuli nge ukusebenza kahle kokuhlunga.
