This PVC coupling with dimensions 195x80 mm x 80mm (oval) features a glue socket connection on both ends that fits directly over a duct, eliminating the need for an additional connector to couple it with the oval cast-in duct.
The oval ducts and fittings have a built-in height of only 90 mm (duct height 80 mm). This makes the system suitable not only for cast-in applications but also for installation in suspended ceilings or other space constraints. The robust impact-resistant PVC makes them durable and capable of withstanding the loads during concrete casting.
Cast-in ducts are ventilation ducts that are integrated into a floor or concrete to enable air distribution or extraction in buildings. These flexible products are designed to be invisible and are commonly used in new construction and renovation projects. Furthermore, a cast-in duct can be used in walls, floors, and/or ceilings. Combined with a straight cast-in duct and various fittings, a ventilation duct can be installed as desired. There are both round and rectangular cast-in ducts. Some advantages of cast-in ducts include: efficient airflow, space-saving, noise reduction, and design flexibility.
The ducts and fittings meet the highest air tightness class, ATC1, as established in NEN-EN 17192:2019. This means that the system is three times more airtight than systems with ATC2, which corresponds to the LUKA air tightness class D. This high air tightness improves both energy efficiency and air quality.
Thanks to the low wall roughness of PVC, there is less dirt accumulation and friction losses are minimal. PVC has the lowest wall roughness of all ventilation ducts, contributing to optimal airflow. Flexible ducts, on the other hand, have the highest wall roughness, although they excel in flexibility.
A unique feature of the system is the presence of additional ribs around the glue socket. These ribs enhance grip and ensure a stronger connection, which is essential during concrete casting.
The ducts are 100% recyclable, contributing to environmentally friendly construction solutions. The use of glue connections makes installation quick and easy, saving both time and costs.
