The insulated manifold box is used for mechanical ventilation systems with heat recovery (MVHR). MVHR manifolds do not need to be insulated onsite thanks to the insulating properties of EPP. Manifold boxes are designed for distribution of 75mm semi-rigid ducting around. The number of connectors varies depending on the user's specifications: 6-13 connection spigots.

The FLX-PLO-EPP-F plenum boxes are part of the FLX-REKU air distribution system designed for domestic mechanical ventilation systems, so-called the MVHR system, to which an air valve and FLX-HDPE / FLX-HDPE-A ducts with a diameter of Ø75 are mounted.

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.

EPP manifold boxes are used for heat recovery ventilation (MVHR). Due to EPP's insulating properties, MVHR manifolds do not need to be insulated. Manifold boxes are intended to distribute 75mm ducting around the house. The number of connectors varies based on the specifications of the user: 4-18 spigots.

The RACAV constant air velocity regulator keeps the air output steady in ventilation systems. The device works without any electric power supply and from the minimum pressure differential shown in Chart 1 to the maximum pressure differential of 1000 Pa. The air velocity stability may be reduced outside the range shown in the differential pressure chart. The regulator can be used in comfort or industrial air supply and air exhaust systems.

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.

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. Lenght EPP ducts 1 m sections Diameters 125, 160 and 200 mm. Wall thickness 15 mm Thermal conductivity 0.039 W / m*K Airtightness class ATC2 (old D) @ 90Pa acc. to PNEN 17192201901

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.

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.

The LDS linear slot diffuser are intended for ceiling or wall installation. The product can supply warm or cold air. The diffuser can feature from 1 to 4 slots, 495 mm or 990 mm in length, depending on the product version. Each slot enables separate air flow direction adjustment and is provided with two deflector vanes. This design enables easy adaptation of the air flow diffusion direction according to actual indoor conditions. With this easy adjustment functionality, the LDS linear slot diffusers are ideal for variable air output ventilation systems

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.

ILA maleend flexible duct connectors are used for joining two round SPIRAL or plain ducts. They are most often used for connecting air handling units, heat recuperation units, and duct fans. The flexible duct connector deadens the vibration generated by the equipment to prevent vibration and noise in the ductwork and ensure improved acoustic performance of the ventilation system. The flexible piece is made from AMT balancing tape, a standalone product available in different sizes and materials, including a heatresistant version. The standard version is male. The femaleended version is available on request for connecting two fittings.

FLXPLO / FLXPRO plenum boxes are components of the FLXREKU system intended for domestic mechanical ventilation systems, also known as mechanical ventilation heat recovery (MVHR) or heat recovery ventilation. The low profile plenum boxes require less installation space than standard solutions, which is very convenient when they should not be prominent once concealed. This advantage helps free up usable indoor area. FLXPLO plenum boxes are made of galvanized steel sheet. Plenum boxes made from stainless steel are available on request. Available also insulated plenum box version FLXPLI and FLXPRI. These plenum boxes have inside a insulation lining made from 9 mm thick rubber foam. FLXPLO plenum boxes are equipped with duct connection spigot Ød2 with a EPDM seal – this type of connection with FLXHDPE ducting is airtight and easy to install.

FLXHDPE and FLXHDPEA plastic ducts are used to air distribution in domestic ventilation systems. Relatively small diameters allow to hide the installation in ceilings, screeds or suspended ceilings. FLXHDPE and FLXHDPEA semirigid ducts are connected to other system components like plenum boxes or distribution boxes with a simple push fit connection. Application of seals on the FLXPLO plenum boxes’ spigots guarantees high air tightness system. FL XHDPE and FL XHDPEA semirigid ducting is made of highimpact polyethylene. This makes the entire ventilation ductwork very durable. FLXHDPEA ducts are complying with European norm EN 171922018 for rigid or semirigid nonmetallic ductwork, which defines the test methods and performance characteristics like airtightness, pressure drop, reaction to fire, resistance to external pressure , thermal resistance and microbial resistance. FLXHDPE75 semirigid ducts without an antibacterial coating are gray.

The FDA212 square 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 of construction products and building elements). The fire resistance was tested as per PNEN 1366 22015 (Fire resistance tests for service installations — Part 2 Fire dampers). The entire manufacturing process meets the requirements of EN 156502010. The FDA212 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 sizes 160x160 – 1000x500 mm. All fire dampers have a torsion spring trip (in FDA212T) or a returnspring actuator coupled with a thermal trip (in FDA212M).
