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.

HRUWALLWI model ductless heat recovery unit comes equipped with a WiFi module. Its basic parameters, including max. heat recovery 82%, airflow rate 60 m3/h, and low sound power level 38 dB (A), are identical to those of the HRUWALL units. Methods for pairing devices and controlling them are different. With the addition of a WiFi module, the device can be connected to a local wireless network and controlled via a mobile app. Moreover, the app allows the pairing of devices by assigning two or more heat recovery units to a group. It is possible to have many groups so that 1 application can serve all HRV units in a building. A temperature sensor and relative humidity sensor are built into the HRUWALLWI, and the app displays their values.

The RAVAV regulator is dedicated for forced ventilation systems and is an important component for installations with variable air flow. The regulator casing is made of Z 275 galvanized sheet. Optionally, it is possible to use the 1.4301 stainless steel to build the casing. Casing sides with factoryinstalled EPDM rubber gaskets ensure tight connection to ventilation ducts. Inside the casing, the adjusting damper is also insulated (depending on the control mechanism). The servomotor is installed on the control unit casing so as to allow for thermal insulation of the system. The regulator is also available in the version with preinstalled 50 mm insulation and a galvanised steel shield. The measuring system based on aluminum impact pressure tubes and pressure relieve stub pipes ensures reliable measuring of the air flow. Sensor, control unit and servomotor are integrated in one device.

The standard duct length is 3000 mm; the sheet thickness for a given diameter is the same as that for the SPR spiral coiled ducts. The ducts of diameter 250 mm or greater feature outer ribbing to improve the robustness and vacuum pressure strength.

The FDA12 round fire dampers are designed for use in general ventilation systems to seal off smoke and fire between adjacent fire partitions. The fire dampers are classified according to EN 135013+A12010P (Fire classification f construction products and building elements). The fire resistance was tested as per PNEN 136622001P (Fire resistance tests for service installations Part 2 Fire dampers). The entire manufacturing process meets the requirements of EN 156502010. The FDA12 fire dampers can be installed in horizontal and vertical fire partitions to provide fire resistance of EI 120 (ve ho i↔o) S (which may depend on the actual fire resistance of the partition). The fire dampers are available in the nominal diameter sizes DN100, DN125, DN160, DN200, DN250, and DN315. All fire dampers have a pull spring control gear and a fusible thermal trip (in FDA12T) or a returnspring actuator coupled with a thermal trip (in FDA12M).

Pressed bends are designed for building ventilation systems based on spiral and plain ducts. Seam welds provide air tightness class D without the need to use any other sealants. In ventilation and heat recuperation systems, the double EPDM gasket provides air tightness class D according to EN 12237. The piece is connected with a duct by inserting one into the other. The pressed form of the ventilation piece helps to reduce the flow resistance and the pressure loss. Material:galvanized steel sheet Degree:90

Round spiral ducts are available in diameters from 80 mm to 1600 mm. The ducts are available as made of 0.4 mm to 1.8 mm thick metal sheet; the ducts in diameters of DN 160 mm or greater are also available with corrugation for improved stiffness and vacuum strength. The corrugations are available as a standard feature for diameters of DN 250 mm to DN 1600 mm. All spiral ducts made from galvanized steel sheet, stainless steel sheet or aluminium sheet meet requirements of air tightness class D according to EN 12237.

Round ventilation duct made of expanded polypropylene (EPP). The most important features of the product are rigid construction, low weight, easy assembly and good thermal insulation. EPP ducts, used, for example, as sections of the supply and exhaust ventilation systems with heat recovery, do not require additional insulation. The system eliminates the formation of thermal bridges. Ducts na fittings do not require additional couplings. Lenght EPP ducts 1 m sections Diameters 125, 160 and 200 mm. Wall thickness 43 mm Thermal conductivity 0.039 W / m*K Airtightness class ATC2 (old D) @110Pa acc. to PNEN 17192201901

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).
