Air duct - Import export

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 GBL iris dampers are essential for smooth control of the duct air pressure. The lever and the iris regulating plates mechanism allow smooth adjustment of the diameter of the orifice(opening). The iristype closure allows throttling of the air flow without turbulence or induct noise. The GBL iris damper can be installed both in air supply and air exhaust ducts. Each Iris damper is provided with two manometer connections. The GBL can be opened to the full clear diameter for easier cleaning of the ductwork. The iris dampers, however, cannot be sealed shut (the maximum closing ratio is ca. 25% of the nominal clear diameter).

The DSQWA rectangular multiblade aluminium dampers can be used to control and isolate air flow in rectangular ductwork. The dampers can be installed in ventilation ducts, as wallmounted air flow regulators, or AHU air flow regulating and shutoff units. All dampers have a housing made of 4 aluminium profiles and a closure consisting of aluminium blades. The blade height is the same for all product sizes. The blades are fitted with gaskets to provide air tightness class 2 as per EN 17512003. The DSQWA damper can have a handoperated damper mechanism QDMPSAL, an externallymounted actuator, or an actuator mounting. The damper mechanism is installed on the outer surface of the housing. The damper blade rotation mechanism features short and long shafts rotating by intermeshed gears installed on bearings. The gears are installed on the outer surface of the housing.

The FLXPLOEPPF plenum boxes are part of the FLXREKU air distribution system designed for domestic mechanical ventilation systems, socalled the MVHR system, to which an air valve and FLXHDPE / FLXHDPEA ducts with a diameter of Ø75 are mounted. Due to their small size, they do not require much space or special installation. This allows achieving a larger usable floor area of the room. The FLXPLOEPPF plenum boxes are made of expanded polypropylene, i.e. EPP, while Ø75 spigots are made of ABS. The material used allows obtaining an aerodynamic shape of the inside of the box which leads to low air resistance.

High-quality MODERN fireplace/ventilation grilles MODERN fireplace grates are made of steel elements properly prepared in the technological process. They have very good mechanical properties, as well as high color stability and thermal resistance. Installation is carried out using the mounting frame attached to the grille. Modern fireplace grates are also used as the end of hot air distribution ducts from the fireplace . The shutter allows you to adjust the air flow through the grille by opening and closing. These grilles can also be used in ventilation installations / risers, they are ideal as an aesthetic finish of chimney ventilation openings in the room.
