Flexible silencers

The SLC and SRC rectangular duct silencers reduce the noise level in ventilation and A/C systems. This silencer type is usually installed between a fan and an air supply or exhaust duct, and upstream of air supply vents. All silencers are made of a housing and inner baffles. The housing is made from galvanized steel sheet and its ends are framed with steel sheet angles. All baffles inside the silencer have a round breast at one end and comprise a galvanized steel frame with a soundinsulating insert which absorbs the acoustic energy from the air flow. The soundinsulating insert is a set of nonflammable mineral wool panels. The outer surface of the soundinsulating insert is lined with a special abrasionresistant textile to protect the mineral wool from wear and tear. The mineral wool panels are finished with a glass fibre lining in black; this lining is suitable for systems with a maximum air flow rate of 20 m/s.

The silencers are delivered with the SPIRAL® system seals in the standard version. The diameter sizes d1 > 315 mm require ordering the NSL male couplings which need to be installed in the silencer before connecting the silencer to the ductwork. The male fittings are available separately. They are not delivered with the silencers. Glass wool thickness inside the silencer 50 mm for SIL50 depends on the outer cladding size. 100 mm for SIL100 depends on the outer cladding size. Insulation Insulation material glass wool. Insulation type trimmed from reel, flexible. Reaction to fire A1 acc. to EN 13162

The HomEvap adiabatic humidifier is designed for domestic mechanical ventilation systems with a maximum airflow 600 m3/h. Filtered water (Legiosafe®) naturally evaporates on a special matrix, and then the humidified air is distributed to the ventilation duct system and to the connected rooms. The humidification process is regulated by a wireless room controller and a duct sensor. Builtin PTC heater compensates for temperature losses caused by the evaporation process. The housing is made of EPP, while the matrix is made of fiber glass.

HHS wall diffuser for fresh air supply. Male connector with gasket for fast connection with SPIRAL® duct. Powder painted with white RAL 9010 colour which provides additional protection from corrosion in places with high humidity, such as bathrooms. An excellent choice when celling mounting is out of the scope or the interior design requires a wall diffuser. It can be used in offices, residential houses and mounted just under the ceiling as well.
