KAIR 100MM ROUND 45 DEGREE ELBOW BEND
Rigid 45 degree bends can be used to run your ductwork around obstacles along walls and into ceilings and offer superior performance and durability over flexible alternatives.
This item is part of the Kair Ventilation System 100 Plastic Round Ducting Range (SYS-100). The Kair Round System 100 (SYS-100) ducting provides superior airflow performance compared to rectangular or flexible duct and should always be considered as a first option if space allows. This system is suitable for extractor fans and cooker hoods and is compatible with an extensive range of fittings outlets and grilles.
Kair plastic ducting is lightweight, durable and suitable for commercial and domestic use. It is perfectly suited for ducting your tumble dryer, bathroom or kitchen extractor fan, hydroponics, in-line extract fans, or cooker hood. It can be used as a part of a long ductwork run for a variety of purposes including whole house ventilation, passive stack vent, positive input, air conditioning, HVAC, and heat recovery systems.
If your duct run passes through a particularly cold area, we would recommend considering using our pre-insulated ducting to avoid condensation building up within your ductwork. Click here to view our range of pre-insulated plastic ducting.
