AMCA, CE / UL Certified Round Axial Jet Fans
Unidirectional / reversible, high temperature-rated, CE / UL certified, silent operation, impulse jet fans for ductless ventilation for road, railway tunnels, underground parking, garage, service tunnels, warehouses etc.
High efficiency, dual speed motor, high temperature rated for 300 deg / 400 deg for 2 hrs, with AMCA sound and air performance certification, UL / CE / TUV certified motors, suitable for ductless ventilation in basement carparks, service tunnels, road & railway tunnels, bunkers, warehouse etc.
Round Jet fans, also known as axial jet fans, impulse jet fans, are used for ductless ventilation and air flow movement. Due to their high thrust force, they form train of invisible, ductless air jets to remove or dilute smoke, toxic gases, temperature, hot air inside enclosed areas, like basement car park, garage, service tunnels, road and railway tunnels.
Round axial jet fans reduce duct cost, requirement of high static fans, high-capacity motor, thus drastically reduce operating cost. It also improves available drive-way space, reduce security cameras block-area. Jet fans are available in single and double / dual speed motor options.
We can supply high performance jet fans of esteemed manufacturers like Systemair, Greenheck, Krueger, Nicotra, Airflow, Witt, Fantech, Novenco, Wolter, Fanair, Maico, Woods, Zetron, Flakt.
We also offer Centrifugal Jet fans for smoke and hot air exhaust in low lying ceiling installation.
