Nano-maska PTFE filtarska membrana koja može učinkovito presresti bakterije i čestice prašine u zraku i ima dobru vodootpornost i propusnost zraka.
The reduced bulk density will allow the material being transported much more quickly to the filter floor, even in layouts that try out to attenuate dust loading to the filters. Regular loading is forty two lbs. per 1000 ft² of filter location.
Systemy techniczne w budynkach są coraz bardzie rozbudowane i skomplikowane. Potrzeba zapewnienia pełnego komfortu sprawia, że rozwiązanie spotykane kiedyś w wysokiej klasy biurowcach czy hotelach coraz częściej trafiają do budynków mieszkalnych czy biur urzędów.
