Air supply flaps
Air supply flaps
Air supply flaps with self-opening and self-closing flaps. When the negative pressure unit is switched-on, the flaps open even at a low volume flow. If the negative pressure is decreasing, the flaps will close automatically.
An optional pre-filter bracket set allows the air supply flaps to be combined with standard pre-filters.
