4inch Plastic Ducting 90 Degree Elbow Bend Joint, a perfect solution for managing your ductwork around obstacles along walls and ceilings. This white plastic 90-degree elbow bend offers a combination of superior performance and long-lasting durability, outshining flexible alternatives.
The male spigot of this elbow bend comfortably fits into the 100mm Round Pipe or the 102mm Flexible Hose. We advise using minimal bends in your duct run to minimize any potential loss of pressure and the same principle applies when connecting smaller to larger ducting.
Remember to avoid narrow ducting when supplying air through a powerful fan as this may lead to increased air noise, potential fan damage, and possible vibration. It offers a static pressure drop in Pascals of 15 l/s = 5.60 Pa – 30 l/s = 21.10 Pa – 60 l/s = 33.10 Pa.
Our elbow bend is designed for ease of installation and durability. It simply requires a push-fit duct and fittings assembly. It can withstand a Max / Min Temperature range of +60°c / -15°c and is compatible with any female part of the 100mm ducting range.
This product’s airflow performance has been independently tested by BSRIA or BRE, ensuring its suitability for compliance with Part F Building Regulations. It’s crafted from high-quality white Polystyrene/Polypropylene plastic Material, ensuring its longevity.
