The FDA-12, FDA2-12 FDA-BU are round, rectangular and butterfly fire dampers designed for use in general ventilation systems to seal off smoke and fire between adjacent fire partitions. Fire dampers are classified according to EN 13501-3+A1:2010P. The fire resistance was tested as per PN-EN 1366-2:2015. The entire manufacturing process meets the requirements of EN 15650:2010.

Fire dampers can be installed in horizontal and/or vertical fire partitions to provide fire resistance of up to EI 120 (ve ho i↔o) S (which may depend on the actual fire resistance of the partition). All fire dampers have a torsion spring trip (T) or a return-spring actuator coupled with a thermal trip (M). The spring-action versions can be provided with optional limit switches.

Airflow CAV and VAV regulators are used to automatically regulate the airflow in the ventilation system. The task of the airflow regulators is to maintain the required airflow rates, allowing to set the optimal climate conditions for each room in the building. The airflow can be regulated both in the supply and exhaust ducts.

Types of airflow regulators:

• constant flow regulators with a fixed set point,
• air flow regulators with switching between two preset values (V ̇min, V ̇max,),
• constant air flow regulators with variable airflow setting,
• VAV variable air flow regulators.

The SPIRAL®system is a proven system of quick-coupled spiral ducts and fittings provided with factory-installed EPDM gaskets. The gaskets provide leak-proof and durable joints between SPIRAL®system components. The system components are available in a full range of diameters from Ø80 to Ø1600 mm and in different materials (galvanized steel, stainless steel and aluminum). SPIRAL system meets the requirements of PN-EN 12237 for air tightness class D (Certificate no. 0103/07 from RISE).

The high-quality of workmanship and factory-installed rubber gaskets enable easy and quick assembly of ventilation ductwork. Ductwork based on SPIRAL®system components guarantees long and leak-proof service life and requires no additional sealants.

EPP ducting is a system of prefabricated ducts and fittings that exploits the advantages of expanded polypropylene. The most important features of the product are stiffness of construction, lightness, ease of installation and good thermal insulation.

EPP ducts are used e.g. as intake and extraction sections in household heat recovery systems. They do not require additional insulation (as the material itself is already an insulator), which significantly reduces installation time.

Each piece can be fastened easily and quickly as no additional fasteners or screws are required. Additionally, foamed polypropylene is easy to cut with hand tools. The system also eliminates the formation of thermal bridges. Due to the low weight of the elements, a suspension system is practically unnecessary.

Advantages of EPP system:

• Simple installation (no additional mounts, tapes, screws, etc.),
• Assembly requires little expertise - EPP elements are simply push-fit to connect; ducts can be cut to match our needs using a knife or a saw,
• The system consists of just a few pieces - only 3-4 (a pipe, bend 45o, bend 90o, connector or a t-piece),
• A lightweight, durable design.
