Parag axial flow fans have an aerodynamic profile with high blade twist angles and large chord widths that give the world’s best efficiencies. Energy efficiency improvements of 20-40% over earlier fans are not uncommon. Blade twist angles up to 44 degrees ensure airflow is uniform hence preventing turbulence. Parag fans are hollow and lightweight which reduces the moment of inertia. Being seamless and UV protected, Parag fans are extremely durable- even having withstood hurricane winds without need for replacement.
