Airfoil Fans

Conventional metal aluminum blades offer a lower lift to drag (Cl Cd) ratio resulting in flow separation and turbulence at the leading edge of the blades causing higher profile loss. ”Parag” provides higher blade twist angle and optimum camber offering the very high efficiency of the fans. Our blade profile, confirming to N.A.C.A. 23012 aerofoil characteristics with high Cl Cd ratio, greater twist, taper, camber and consistent FRP blade shape, can improve total efficiency up to 90% resulting in considerable energy savings or higher air flow for the identical operating conditions (Air Flow, Total Pressure and RPM) in a given system.
