Centrifugal Blowers

Material Options & Operating Temperature Ranges :

Centrifugal blowers are fabricated using different material combinations based on chemical exposure, operating temperature, and structural requirements.

• PP (Polypropylene Copolymer) : Used for general ventilation and mildly corrosive fumes. Suitable for ambient to moderate temperatures up to 80–90°C, with good impact resistance and fabrication flexibility.

• PPH (Polypropylene Homopolymer) : Offers higher rigidity and chemical resistance than PP. Commonly selected for chemical exhaust systems operating up to 90–100°C.

• PVDF (Polyvinylidene Fluoride) : Preferred for highly corrosive gases and aggressive chemical vapors. Provides excellent chemical resistance with reliable performance up to 120–150°C, depending on design.

• HDPE (High-Density Polyethylene) : Suitable for low-pressure air handling and moist environments. Recommended for ambient temperature applications up to 60–70°C, especially where abrasion resistance is required.

• PVC (Polyvinyl Chloride) : Used for low-temperature corrosive gas handling. Performs well up to 60°C, commonly applied in ventilation and scrubber exhaust systems.

• FRP (Fiber Reinforced Plastic) : Used where higher structural strength is required along with corrosion resistance. Suitable for ambient to moderate temperatures, depending on resin system.

• PP–FRP Lined Construction : Combines the chemical resistance of polypropylene with the structural strength of FRP. Used for larger blowers handling corrosive fumes at moderate temperatures.

• HDPE–FRP Lined Construction : Provides abrasion resistance of HDPE with added stiffness from FRP backing. Suitable for ambient temperature air handling in corrosive environments.

• MS–FRP Lined Construction : Mild steel provides mechanical strength, while FRP lining protects against corrosion. Used for heavy-duty blower housings operating at ambient temperatures with corrosive gases.

Key Advantages :

• Excellent resistance to corrosive fumes and vapors.

• No rusting, scaling, or chemical degradation.

• Stable airflow and pressure performance.

• Lower operating and maintenance costs.

• Custom material selection based on process conditions.

Applications & Industries :
