125mm Solid Ducting & Accessories
Shop 125mm solid ducting and accessories at Order Electrical for building efficient rigid ventilation routes using compatible 125mm (5 inch) extractor fans and ventilation equipment.
Sitting between the commonly used 100mm and larger 150mm systems, 125mm rigid ducting provides additional airflow capacity while retaining a relatively compact duct diameter. This makes it a useful option for ventilation systems where 100mm ducting may not provide the required capacity.
Also known as 5 inch ventilation ducting, this size can be used for extraction from kitchens, utility rooms, larger bathrooms and other domestic or light commercial spaces, subject to the airflow requirements of the installation.
A complete 125mm duct route can be assembled using compatible straight duct sections, bends, elbows, connectors, couplers, tees, reducers and termination accessories. These components allow the system to be configured around walls, ceilings and other building features.
The smooth internal surface of correctly installed solid or rigid ducting can provide an efficient airflow path between the extractor fan and discharge point. Careful route planning can further improve performance by avoiding excessive duct lengths and unnecessary changes in direction.
Reducers and adaptors can be particularly useful where a 125mm system needs to interface with ventilation components of another size. However, changing duct diameter can affect airflow performance, so the complete system and fan specification should be considered rather than selecting fittings solely by connection size.
When planning a 125mm ventilation system, check the fan spigot diameter, required airflow, duct length, number of bends and compatibility of all fittings. Condensation and insulation requirements should also be considered where ductwork passes through lofts, roof spaces or other colder areas.
