The Elta 018 – 150-DAMPER is a 150mm circular backdraft damper designed to stop the reverse flow of air when a fan is inactive. Housed in a robust galvanised sheet steel casing, it uses spring-loaded aluminium blades that automatically close when airflow ceases.
This damper is ideal for maintaining system efficiency and preventing unwanted air infiltration in ventilation systems. It is easy to install and ensures reliable operation in both residential and commercial ductwork applications.
