Centrali di trattamento aria Air handling units By - pass dei filtri / Filter by - pass leakage Il trafilamento dell’aria attorno al telaio dei filtri viene sottoposto a prova ad una pressione di -400 Pa (filtri a monte del ventilatore) e ad una di +400 Pa (filtri a valle). Il trafilamento viene rapportato alla portata nominale della centrale e in base alla classe di filtrazione non deve superare i limiti sottoindicati. Filter by-pass leakage shall be tested both at 400 Pa positive pressure (filter upstream of the fan) and 400 Pa negative pressure condition (filter downstream of the fan). The...
