Robust Design for Harsh Chemical Environments

The Centrifugal Corrosion-Resistant Fan is a heavy-duty industrial solution specifically engineered for conveying corrosive gases and chemical fumes. Designed and manufactured in compliance with stringent standards including GB/T 13275, GB/T 2888, and HG/T 20696, this fan also incorporates material selection guidelines from ISO 12944 for corrosion environment classification. Every component is fabricated from corrosion-resistant materials and sealed using advanced technologies to withstand long-term exposure to strong acids, alkalis, and organic solvent vapors commonly encountered in chemical processing, electroplating, pickling, and wastewater treatment plants. Its design prioritizes not only aerodynamic efficiency but also long-term structural integrity and leak-free operation.

Engineered Performance with Verified Durability

This centrifugal corrosion-resistant fan delivers reliable and consistent performance under demanding conditions. With a rated airflow of 8,000 m³/h and a total pressure of 2,200 Pa, it maintains high efficiency in real-world operation. Post-installation measurements confirm stable performance, with actual airflow ranging from 7,800–8,200 m³/h, total pressure between 2,100–2,300 Pa, and static pressure of 1,700–1,900 Pa. Full-pressure efficiency reaches 76–79%, ensuring energy-efficient operation in harsh environments. Key components, including the impeller and housing, are constructed from PP, PVDF, FRP, or fully welded and passivated 316L stainless steel. The shaft is protected by a corrosion-resistant sleeve, while dual mechanical seals with buffer fluid systems or fluorocarbon lip seals effectively prevent toxic fume leakage.

Ideal for Critical Fume Extraction Systems

In applications such as electroplating workshops, the Centrifugal Corrosion-Resistant Fan plays a vital role in maintaining environmental safety and operational continuity. It is typically installed upstream of scrubber towers to extract acidic and alkaline fumes collected through enclosed hoods and PP ducting. Its all-nonmetallic or surface-treated metal construction provides excellent resistance to chemical attack, while precision sealing ensures that no hazardous emissions escape into the workplace. Built for years of reliable service in aggressive atmospheres, this fan is an essential component of modern industrial ventilation systems where corrosion resistance is critical.
