PP Fan

PP fans are an important category of corrosion-resistant fans or plastic fans. While not entirely made of PP, the core motor part is still metal, but the "wet section" of the fan – that is, all parts that come into direct contact with the conveyed gas – are all made of PP material, formed through injection molding or welding. This allows them to resist corrosion from the vast majority of acids, alkalis, and organic solvents.

High strength and wear resistance:

• With reasonable structural design (such as stiffeners) and high-quality PP material, the PP fan boasts sufficient mechanical strength and rigidity, while the PP material itself also features certain wear resistance.

Smooth operation, low noise:

• The PP impeller has been dynamically balanced, ensuring smooth operation at high speeds with relatively low noise and vibration.

Economical and practical

• At the same corrosion requirements, its manufacturing cost is significantly lower than that of stainless steel or glass fiber fans, offering an excellent cost-performance ratio and is the preferred choice for handling medium to low concentration corrosive gases.

PP Centrifugal Fan

Operating Principle: Utilizes a high-speed rotating impeller to accelerate the gas, then converts the kinetic energy into static pressure within the spiral casing, thereby expelling the gas. Its feature is the high wind pressure produced.

Application: This is the most common type, mainly used in ventilation systems with pipes, where it is necessary to overcome the resistance of pipes and purification equipment (such as scrubbers, activated carbon boxes). For example, as a matching power fan for fume hoods, PP ventilation cabinets, and PP scrubbers.
