4-10 series centrifugal ventilation fan

The 4-10 series centrifugal Fan can be used for indoor ventilation in general factories and large buildings.

It can be used as both an input gas and an output gas. The type of gas transported is air and other non-self-igniting, non-self-explosive, non-surrounding, harmless to the human body and is non-corrosive to steel materials.

4-10 series centrifugal ventilation fan Application

Centrifugal fan is widely used in the cement industry, building materials industry, environmental protection industry, metallurgical industry, power industry projects such as large-scale dust collector, industrial boilers, ventilation systems, cooling.

4-10 series centrifugal ventilation fan Features

When the pressure requirement is met, a large gas flow can be output, and the noise is very low.

The V-belt drive makes your fan to operate at the optimum speed. Installation is simple and does not require the support of professional technicians.

The airflow channel and the impeller are optimized several times, which is more efficient and energy-saving than ordinary large-flow fans.

Made of high quality carbon steel, Stainless steel or other metal materials can also be used according to user requirements.

The impeller is annealed to completely eliminate the internal stress generated during welding, ensuring that the impeller does not undergo creep and cracks.

After the production is completed, all products are tested for running and vibration values for reliable operation.

Installation is simple and does not require the support of professional technicians.
