ROOF EXTRACTOR – CENTRIFUGAL TYPE
A Centrifugal Roof Extractor is a roof-mounted ventilation system designed to efficiently remove stale, hot, humid, and contaminated air from industrial and commercial spaces. Its centrifugal impeller provides reliable air extraction while the roof-mounted design saves indoor space and supports continuous ventilation.
