FITFIRE® Vent:
for the rehabilitation of ventilation ducts
FITFIRE® Vent is the inflatable thermosetting liner developed for the non-destructive rehabilitation of old ventilation ducts. In other words, an efficient, non-invasive and fully Made in Italy solution to restore entire ventilation systems, even complex ones, without replacing pipes and without demolition.
Designed for residential and industrial applications, FITFIRE® Vent transforms existing ductwork into modern, certified and compliant systems. The composite material from which it is made, developed by Beca Engineering experts, perfectly adheres to the duct walls, even in the presence of bends or irregularities, restoring a high-performance monolithic structure without joints or leakage points.

How FITFIRE® Vent
Definitive, custom and demolition-free solution in 5 steps
1. Video inspection > 2. Application of the lower and upper sleeve with pressure gauge > 3. Forced air injection > 4. Steam injection > 5. Cutting of excess liner.
And the ventilation ducts are ready for use!
Installation of FITFIRE® Vent is simple and fast: the liner is inserted into the existing ventilation duct and inflated with air and high-pressure steam.
In this way, the thermosetting composite material perfectly adheres to the internal surfaces and polymerises, forming a new continuous ventilation duct without weak points where leaks could occur.
The entire process is completed in just a few steps and does not require specific masonry work or invasive interventions: the result is a renewed ventilation system that is compliant with regulations and ready for use within a few hours.
