Renson EasyFlex Semi Rigid Duct system

Easyflex is a semi-rigid, corrugated air duct made out of polyethylene with an external diameter of 140x64mm and an equivalent inner diameter of 90mm. The smooth inner surface of the double walled air duct is treated with anti-static and antibacterial additives to prevent dust accumulation and bacteria outbreaks.

Thanks to its size, an airflow of 57m³/h is achieved at a design speed of 2,5 m/s. A high airflow combined with a low air speed guarantees a silent air duct system.

The limited height of the Easyflex air duct allows it to be installed easily into false walls/ceilings, in concrete or screed.

To Ventiate

Ventilation is an essential part of our current way of living. It protects your home against moisture, mold & unpleasant smells and it allows you to enjoy fresh air in a controlled and safe way.

On the one hand a ventilation system needs to comply with a number of technical demands such as achieving the required airflows per room. On the other hand it also needs to comply with certain comfort demands, e.g. limiting the sound production of the system.

Your guarantee on airflow, sound, air tightness & hygiene

Airtight
The unique linking system ensures an almost perfect airtightness. The connection piece with integrated rubber sealing is pushed into the semirigid duct and clamped off with a quick release, making the connection completely airtight. The quick release can be fastened to the surface so that the connection cannot move.

Guarantee on airflow
A large diameter was purposely chosen when designing the Easyflex semi-rigid ducts, allowing the system to transport large airflows (57m³/h) at low air speeds (2,5 m/s). This dimensioning combined with an excellent airtightness ensures you that the designed airflows for each room will be achieved (when the installation instructions are respected).

Acoustic comfort
The big dimensions of the air duct system also impacts the acoustic comfort of the system seeing as the chance on flow noise due to high air speeds is drastically reduced. Furthermore it is possible to equip the extraction grills in rooms with an required airflow of ≤50m³/h with an acoustic damper to limit any possible noise at the level of the extractiongrills. The shape of the connection pieces for the extraction grills also contributes to the acoustic comfort. Passing from the flat semi-rigid duct to the extraction grill (Ø90 ” Ø125mm) a pressure drop is created, resulting in an extra low air speed over the extraction grill.
