Round Control Dampers

AMCA, CE Certified Round Impulse Jet Fan

Round Jet Fan 

AMCA, CE-certified jet fan 

Unidirectional/reversible, high temperature-rated, CE/UL certified, silent operation, impulse jet fans for ductless ventilation.

Round jet fans are great for ductless ventilation systems. They work well in tunnels, car parks, garages, warehouses, storage areas, silos, bunkers, and hotel facility tunnels. These fans are very efficient and quiet. They install quickly and perform well. They have a dual-speed mode for energy efficiency and lower costs. They are designed for flexible ventilation needs.

These fans have strong air force to remove toxins, circulate fresh air, and exhaust hot smoke. They cut installation costs by avoiding extra ductwork. They also lower ceiling height needs and make maintenance easier. They do not block CCTV security views.

Jet fans improve visibility, lower spot temperatures, and remove smoke and gases during emergencies.

We offer jet fans from top brands like Systemair, Greenheck, Krueger, Nicotra, Airflow, Witt, Fantech, NOVENCO, Wolter, Fanair, Maico, Zetron, and Flakt.
