This silencer for domestic use is a special project of which we are particularly proud. From the idea to the drawings, planning, solutions, prototyping, development and production, every step has been managed by MPE. The benefits of the product are obvious, such as noise reduction and reduced heat loss in the home. It is made up of a tube and a helical fan in porous expanded polypropylene, also known as open-cell polypropylene (P-EPP), and is ideal for air intakes on perimeter walls. P-EPP is always preferred for its sound-absorbing properties and durability, two aspects that ensure that air quality is not compromised.
