PPH Fan

The PPH fan of China Xinda Chemical is specially designed for highly corrosive ventilation environments. The core components of the fan are made of high-crystallinity polypropylene homopolymer (PPH) through high-pressure injection molding and hot air welding processes. They can withstand the vast majority of corrosive gases such as acid mist and alkali mist for a long time, completely solving the problem of easy rusting of metal fans.

This fan operates smoothly with low noise, and its weight is only about one-third of that of a steel fan of the same specification. It is more convenient for transportation, installation and daily maintenance. It is widely used in chemical workshops, electroplating production lines, laboratories, and industries such as metallurgy and pharmaceuticals. While providing reliable ventilation capacity, it significantly reduces long-term maintenance and replacement costs.

Working principle and structural composition

PPH fan operates based on the principle of converting kinetic energy into potential energy: the high-speed rotating impeller accelerates the gas. Through changing the direction of the gas flow and the deceleration process, kinetic energy is converted into pressure energy. The increase in pressure mainly occurs in the impeller, followed by the diffusion process. Its core structure includes an air inlet, impeller, air outlet, drive device (motor and transmission system), etc. The impeller is made of PPH (polypropylene) to ensure stable operation in corrosive environments.In the single-stage fan, the gas enters the impeller from the axial direction and then flows radially. In the multi-stage fan, the air is pressurized step by step through the reflux.

Performance advantages

Strong corrosion resistance: PPH material (polypropylene modified material) can withstand acid, alkali, organic solvents and other corrosive media, suitable for chemical, sewage treatment and other strong corrosive environment, and high temperature resistance is better than the traditional PP, PVC materials.

Low noise operation: low noise during the operation of the equipment, will not interfere with the surrounding environment and personnel, suitable for laboratories, food processing plants and other occasions with high requirements for quiet environment.

High efficiency and energy saving: By optimizing impeller design and air flow path, it can reduce energy consumption while achieving high pressure and large air volume, which is an ideal replacement product for boiler and induced draft fan.

Flexible structure: It supports two types, right-rotating (the impeller rotates clockwise) and left-rotating (the impeller rotates counterclockwise), and can be selected according to installation requirements to adapt to different pipeline layouts.
