Professional Components for Heat Recovery Systems

High-quality mounting materials are the foundation of a durable, quiet, and energy-efficient ventilation system. Even the most expensive heat recovery units and ductwork cannot function correctly if air leaks occur at the joints or if vibrations are transmitted to the building structure. The use of specialized seals, sleeves, and tapes prevents working pressure loss and protects the system from hidden defects behind suspended ceilings or within floor screeds.

We offer a carefully selected range of professional accessories for assembling plastic flexible ducts and distribution manifolds. All elements are calibrated to the standards of modern heat recovery systems, ensuring fast and reliable "push-fit" connections.

Complete Range of Elements

Our catalog features all the necessary parts for the neat and technologically correct installation of ventilation routing:

Connection & Sealing

Sleeves and seals: Rigid plastic and elastic rubber sleeves, as well as EPDM rings. They guarantee tight pipe connections and a high airtightness class.

Fixing & Blanking

Brackets and caps: Components for securely fixing duct runs to ceilings/floors and hermetically sealing unused ports in distribution boxes.

Professional Tapes

Aluminum and perforated tapes: Heat-resistant self-adhesive tapes (reinforced and smooth) for joint insulation, and steel tapes for suspending main ducts.

Regulation & Filtration

Dampers and filters: In-duct acoustic dampers for airflow balancing and conical pre-filters to protect anemostats from dust.

Professional Tools

Specialized cutters: Tools for perfectly straight cutting of corrugated pipes (SK10). Eliminates damage to sealing rings during assembly.

Advantages of Specialized Accessories

  • High compatibility: All caps, sleeves, and seals strictly correspond to the fitting dimensions of flexible ducts (63, 75, 90 mm), minimizing the risk of assembly errors.
  • Accelerated installation: Thanks to glue-free connection technology (push-fit) and the use of professional cutters, routing time is significantly reduced.
  • Reliability for concealed mounting: The materials are resistant to the pressure of concrete mixtures, corrosion, and temperature fluctuations, ensuring the integrity of utilities hidden in floors or ceilings.

Important Mounting Aspects

Duct Preparation (Cutting)


To ensure an airtight seal, the end of the corrugated pipe must be cut strictly at a 90-degree angle. Using a specialized cutter prevents burrs that can damage the rubber gasket when connecting to the manifold.

Port Blanking


All unused ports on distribution boxes must be securely closed with appropriate caps (plastic or honeycomb rubber). This is critical to maintain the calculated working pressure within the system.

Joint Sealing


Reinforced or smooth aluminum tape is used for the final fixation of elements and protection against micro-leaks. Before taping, ensure that the surfaces of the plastic parts are dry and free from construction dust.
