This coupling piece is part of Renson’s EasyFlex duct system. The unique coupling mechanism provides an almost perfect airtight seal. The piece is equipped with rubber seals on both sides. Thanks to these seals, the EasyFlex system falls under airtightness class D, which results in up to three times less leakage compared to class C. The connection can be reinforced with PVC tape, although this is not strictly necessary.

We had a great experience with Monsif and his team. With the Duco Energy Premium WTW-all-in-one package we were given all the information we needed. They inspected our house and came with an complete tailored solution for our house. We now have a quiet and really affordable wtw installation.
Their service is terrible, they do not comply with the delivery time, their work is not organized, I was very dissatisfied and their prices are quite expensive, I do not recommend it
we hired Moncif (wtw.nl) to advise and install a Zenhder Q in our place. Very knowledgeable and carefull on the details. Took care of many details to guarantee the optimal flow and low noise. We had few issues with timelines but Mocif was aways available and went beyond to guarantee all is perfect and in place. Definitely recommend and thank you for the great service.
