Corrosion-proof fans employ impellers and housings crafted from FRP, PVC-lined steel, or specialty alloys (e.g., Hastelloy) to resist aggressive chemicals, salt spray, and acidic vapors. They excel in chemical plants, desalination, and wastewater treatment.
Flow capacities range from 5,000 to 100,000 CFM at pressures to 4 kPa. Protective coatings—epoxy, PTFE, or rubber linings—further extend service life. Bearings and fasteners are selected for chemical compatibility.
Variable speed control enables demand-based ventilation, adjusting airflow to process requirements, reducing energy use and wear. Corrosion-proof fans deliver reliable airflow where standard materials fail.
