Duct silencer RS Description Silencing of the duct silencer type RS in accordance with the absorption principle is done by means of an annular chamber filled with mineral wool according to DIN 4102 A2 non-flammable, mineral wool with glass silk cover. The RSM type contains an additional central baffle with mineral wool filling and glass silk cover, which is covered with a galvanised perforated sheet in abrasion-resistant manner toward the air flow. For maintenance, service, retrofitting, etc., inspection openings in sufficient number and size must be provided on-site. Construction Outer jacket...
