Designers of Madok heat exchangers, stainless steel pressure blowers, induscr draft ventilators, force draft ventilators, leader ventilators, high pressure centrifugal blowers, high CFM axial fans, high air flow ventilators, dust collecting fans, radial pressure blowers, vacuum blowers & fans, pneumatic conveying, material handling fans and blowers, stainless steel ventilation fans, air handling fans, airhandling blowers, FRP pressure blowers, SST pressure fans, oven & dryer circulation fans, drying blowers. Aerofoil design of fan impellers ensures higher efficiency, lower noise levels & less power consumption. The aerodynamically designed impellers of fans, fabricated by composite material can be an excellent alternative to ensure enhanced efficiency & appropriate energy savings apart from a wide gamut of critical advantages. In a blower, it has an opposite effect on the same motor driving a fan blade. For instance, the load on the motor decreases when the motor is driving a squirrel cage blower. As the system becomes clogged, the blower speeds up. On the other hand, the load on the motor increases and the fan slows down as the airflow system becomes clogged with fan blades.
