In 2011, a client in Bangladesh proposed that their country is very hot all year round, so fans they need must be different from those in other countries.

According to the requirements of the client, we made corresponding modifications to the fan motor, a two- pole motor was designed, which could run at an ultra-high speed of 2700 rpm, which was twice as high as our conventional 1200 rpm.

At the same price, the air volume could be increased by 43%, which not only met the client’s requirements for high speed but also met the client’s demand for product cost performance.
