China factory Xinda Chemical's PPH anti-corrosion fans are designed for highly corrosive gas environments.Fan impellers, shell and other core components are made of high crystalline polypropylene homopole (PPH), which can withstand more than 95% of hydrochloric acid, hydrofluoric acid and other strong corrosion media for a long time, and the working temperature range is wide (-20℃ to 100℃), which solves the corrosion problem of metal fans from the root. The equipment operates smoothly with low noise.
It supports direct connection or belt drive and can be equipped with explosion-proof motors. The Angle of the air outlet can be customized as needed, and the installation is flexible. Its structure is sturdy and durable. In applications of ventilation and exhaust gas removal in highly corrosive environments such as chemical plants, electroplating plants, and laboratories, it has significant advantages in terms of service life and maintenance costs.
Our PPH anti-corrosion fan is a ventilation device that combines PPH material with anti-corrosion design. Its core advantages lie in corrosion resistance and chemical stability. PPH (polypropylene homopolymer) material has excellent resistance to bending fatigue. It can be bent multiple times at room temperature without damage and has good heat resistance. The products can work at temperatures below 80℃ without deformation.
It has outstanding chemical stability and can withstand various corrosive media such as acids, alkalis and salts. The structure of a fan is typically composed of a PPH plastic welded impeller (which has undergone static and dynamic balance tests and operates smoothly), a volute casing, a convergent streamlined air inlet, and a transmission group, etc. Some components may also be made of materials such as fiberglass reinforced plastic (FRP) to enhance anti-corrosion performance.

Chemical industry: Dust collection, exhaust and supply air in processes such as chlor-alkali chemical engineering, non-ferrous metal smelting, rare and precious metal smelting, and the production of ferric chloride/ferric bromide.
Laboratories and special industries: electroplating equipment factories, battery factories, forced air supply in papermaking processes, deodorization in sewage treatment, and other environments containing acidic gases or flammable and explosive substances.
Environmental protection system: It is used in conjunction with waste gas purification equipment (such as PP spray towers, desulfurization towers) for the transportation and treatment of corrosive waste gas.
Eliminating toxic and harmful gases: PPH anti-corrosion fan，by means of the principle of centrifugal force,can discharge the corrosive gases, dust or odors in industrial sites to improve air quality.
Control environmental parameters: Assist in regulating the temperature and humidity in the workshop to create a safe working environment for employees and protect production equipment from corrosion at the same time
