Flexible duct system REC Flex System

Why Choose a Flexible Duct System?

Flexible duct systems are rapidly gaining popularity in new construction and renovation projects due to their clear advantages over older technologies. These aren't just pipes – they are an engineered solution solving key ventilation problems.

1. Space Saving and Compactness

One of the biggest advantages of the REC Flex System is its incredibly low profile. Standard ducts are only 75 mm or 90 mm in diameter. This allows them to be easily concealed:

• In minimally lowered suspended ceilings (requiring only ~10-12 cm space);
• Inside concrete floors (screed);
• Within timber frame partitions.

This is the ideal choice for spaces where preserving maximum ceiling height is a priority.

2. Exceptional Sound Insulation (No "Crosstalk")

In traditional systems, sound often travels from one room to another via the main trunk duct. The REC Flex System uses a manifold (radial) layout: each air supply or extract point has its own separate duct running directly from the central manifold. This means:

• No sound transmission between rooms (crosstalk effect);
• Manifolds with sound insulation (e.g., LFT-I series) additionally dampen fan noise;
• The smooth inner surface of the duct reduces airflow noise (whistling).

3. Hygiene and Healthy Microclimate

The ventilation system is the "lungs" of your home, so hygiene is critical. REC Flex HDPEA ducts are made from high-quality, virgin polyethylene and feature:

• Antistatic properties: Dust does not adhere to the duct walls, keeping the system cleaner for longer.
• Antibacterial coating: The inner layer prevents the growth of bacteria, mold, and fungi, ensuring that only clean air enters your rooms.
• Certified quality: The materials are odorless and safe for human health.

4. Fast and Airtight Installation

The REC Flex System is designed to minimize installation errors and speed up the work:

• Flexibility: Ducts are easy to bend around obstacles, eliminating the need for numerous elbows or fittings that increase resistance.
• "Click" system: Components connect simply and reliably. Using rubber gaskets (RE) ensures the highest airtightness class, so you don't lose pressure or energy.
• Simple balancing: Airflows are easy to balance using dampers in the manifolds or ducts.

How Does the REC Flex System Work? Key Components

For the system to run smoothly, it is important to choose the right components from our wide range:

• Flexible Ducts (REC Flex HDPEA): The main "vessel" connecting the manifold to the room. Available in 75mm and 90mm diameters.
• Air Distribution Manifolds (Boxes): The central hub distributing air from the heat recovery unit to individual ducts. We offer insulated and non-insulated versions with various numbers of branches.
• Diffuser Boxes (LDL/LDL-P): The element connecting the flexible duct to the visible diffuser in the ceiling or wall. Available in plastic and metal variants.
• Accessories: Sealing gaskets, end caps, couplings, and dampers – everything needed for a professional installation.
