KAIR 100MM ROUND 90 DEGREE BEND
90 degree bends can be used to run your ductwork around obstacles along walls and into ceilings and offers superior performance and durability over flexible alternatives. Total space requirement: 136x136x103mm.
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.
We always recommend to use as few bends as possible in your duct run to reduce any loss of pressure, this also applies when connecting smaller to larger ducting.
When supplying air through a powerful fan, ensure that the ducting is not too narrow as this could lead to an increase of air noise, damage to the fan and potential vibration.
Through the use of adapters, multiple connections to all other systems are possible.
Our system 100 is commonly used in bathrooms or to branch out from larger systems to smaller rooms.
Here at i-sells.co.uk we stock a large range of galvanised products including 90 degree and 45 degree bends. We recommend our 'safe seal' galvanised bends, which are available in a huge variety of sizes from 63mm up to 1600mm.

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.

Hi Can I connect 150 mm Semi Rijid Aluminium Ducting to 150 mm Round 90 Degree Bend also can I connect a 150 Round 90 Degree Bend to 150 mm Round Plastic Ducting
Thank you for your question. Yes you can fit the semi rigid ducting to the bend and use a quick release worm clip to secure the bend to the ducting and the bend will fit into the plastic duct just seal the joint with some duct tape.
