Silencer
Rectangular silencers reduce noise in ventilation and air conditioning systems. This type of silencer is usually installed between the fan and the air supply or exhaust duct.
All silencers are made of housing and internal cassettes. The housing is made of galvanized steel sheet.
All muffler cassettes have a round end at one end, which consists of a galvanized steel frame with a sound-insulating insert - a box that absorbs acoustic energy from the airflow.
The outer surface of the soundproof cassette is covered with a special abrasion-resistant fabric to protect mineral wool from wear.
Mineral wool panels have a fibreglass lining in black - this lining is
suitable for systems with a maximum airflow speed of 20 m / s.
The maximum heat transfer medium temperature is 250 ° C.
