Ductwork branches and tees are fittings used to divide, redirect and distribute air from a main duct run to secondary sections of a commercial ventilation system. This guide explains their purpose, key differences, airflow considerations and selection factors.
Ductwork reducers connect duct sections of different sizes, allowing airflow systems to transition efficiently between main runs, branches and equipment connections. This guide explains their purpose, common types, selection factors and installation considerations.
Galvanised and stainless steel ductwork both have important roles in commercial ventilation systems. This guide compares corrosion resistance, hygiene, cost, fabrication, maintenance and typical applications to help specify the right material.
Flexible ducting is primarily used for short connections in ventilation and HVAC systems where movement, restricted access or awkward alignment makes rigid ductwork impractical. This guide explains common applications, material considerations, performance limitations and when to transition to rigid spiral ducting.
Volume control dampers are adjustable ductwork components used to regulate, balance or isolate airflow within ventilation and HVAC systems. This guide explains how they work, where they are fitted, common types and key selection considerations.
Ductwork access doors provide a controlled opening into a ventilation or HVAC duct system. They enable inspection, cleaning, testing, adjustment and maintenance without dismantling duct sections. This guide explains the main types, applications and selection considerations for commercial ductwork.
Spiral ducting is usually joined using slip-fit connections, collars or flanged connections, then sealed and mechanically secured where required. The right method depends on duct diameter, pressure, leakage expectations, access and the fitting being connected.
Fusible links are heat-sensitive mechanical release components commonly used in fire dampers, fire shutters and related passive fire protection equipment. This guide explains how they work, where they are used, their limitations and the practical considerations for specifying, installing, inspecting and replacing them.
Circular and rectangular ductwork both have important roles in commercial ventilation and HVAC systems. The right choice depends on airflow requirements, available space, pressure, installation constraints, access for maintenance and project budget. This guide compares their practical differences to help buyers, designers and installers select the most suitable ductwork format.
