Thanks to our system pipes, the times of subsequent incorporation of a backflow flap are a thing of the past.
A backflow flap is only recommended for use with mechanical extract ventilation systems. At FLECK, if necessary, the backflow flap is already integrated in the system pipes for the 4-in-1 flat roof vent. There is no additional cost and effort for the subsequent installation. The system pipes are delivered preassembled. That not only saves transport and installation time but also time spent searching for and procuring the materials. The time gained can be optimally used for other work. Together with the FLECK 4-in-1 flat roof vent, an unbeatable symbiosis results. On request, the system pipes at FLECK are also available with thermal insulation.
Due to its modular design, the 4-in-1 flat roof vent has innumerable advantages such as multiple possible uses, smaller space requirement, faster working or the more precise-fitting installation.
The system pipes with backflow flap belong to the optional 4-in-1 flat roof system from FLECK. The 4-in-1 flat roof vent is the preferred vent of roofers and the favourite for new build, modernisation and renovation. The coordinated components make sure that the installation is easier, safer and faster. The vent can be optionally used as:
The 4-in-1 flat roof vents with integrated KWA (German: Kondens-Wasser-Abschneider – condensate separator) has particularly proven its worth. The condensate formed on the inside is intercepted by the KWA optionally integrated in the upper pipe and is discharged onto the roof via a hole. This prevents the condensate from flowing back into the pipe and thus damaging the motor connected to the ventilation.
