The use of forward and backward centrifugal fans

The composition and application of the backward inclined centrifugal fan:

The fan is composed of an external rotor asynchronous motor, plastic/aluminum impeller, etc. The low temperature rise of the motor has the unique advantage of ventilation, heat dissipation and self-cooling. Thereby extending the reliability of fan life. The fan is a backward-curved impeller, which has the characteristics of compact structure, large air volume, high static pressure, low vibration, low noise, and convenient installation. It is mainly used for purifying workbenches, purification units, ventilation duct dust removal, purification of air conditioning systems, environmental protection and pollution control and other supporting refrigeration equipment.

The composition and application of the forward-inclined centrifugal fan:

This series of fans is composed of an external rotor motor, a plastic forward-bending or metal forward-bending impeller, and a plastic or metal volute. It has the characteristics of compact structure, small size, light weight, and convenient installation and use. Widely used in automatic control devices, forced ventilation of electronic equipment and indoor pipeline dust removal, exhaust, heat removal, environmental protection, air purification and pollution control and other occasions.

The centrifugal fan with forward tilt and backward tilt mainly refers to the different blades of the assembled fan. The forward tilt type is generally called a blower, and the backward tilt type is generally called an induced draft fan. The difference is the length of the impeller rung and the edge of the impeller.

The forward tilt is parallel to the edge of the impeller, and the impeller outlet angle is greater than 90 degrees. The forward tilt impeller is also called the forward tilt impeller. The forward tilt impeller is mostly high pressure. The backward tilt is not parallel to the impeller, and the difference between the length and the edge of the impeller is a few centimeters or a few millimeters. It means that the outlet angle of the impeller is less than 90 degrees. The backward tilt impeller is also called the backward tilt impeller.
