BirnePower Connecteur avec Clapet Anti-Retour pour Gaine Plate 204x60 mm en ABS. Manchon de Raccordement Ventilation Hotte et VMC. Blanc (1 Pièce)

EFFECTIVE PROTECTION: The large BirnePower flat duct connector (model KP204-22) is equipped with an integrated check valve. This clever valve opens only in the direction of the exhaust airflow and closes automatically to effectively prevent the intrusion of cold drafts, unpleasant odors, or insects from outside. HIGH-QUALITY ABS MATERIAL: Unlike simple PVC fittings, this connecting sleeve is made from premium, high-strength ABS plastic. This makes it extremely dimensionally stable, shatterproof, durable, and resistant to temperature fluctuations. PRECISION-FIT DIMENSIONS: The connector is precisely tailored to wide rectangular ventilation ducts measuring 204 x 60 mm (System 204). It ensures a seamless, secure, and airtight connection between two large flat ducts within your high-performance ventilation system. EASY INSTALLATION: The fitting is designed as a practical plug-in system (socket). During installation, the 204x60 mm flat ducts are simply inserted into the connector on both sides. For maximum airtightness, we recommend additional securing with standard ventilation tape. VERSATILE USE: This accessory is essential for the energy-efficient installation of exhaust systems with high airflow. Ideal for connecting high-performance range hoods, air conditioning units, and ventilation systems in large kitchens, windowless rooms, or commercial spaces.
