The POPULA Solution: 4-72 Series Centrifugal Fan

Instead of dealing with intermediate agents, the plant’s engineering team contacted POPULA, a 100% Direct Source Manufacturer with 30 years of expertise in industrial ventilation.

After analyzing their workshop dimensions and environmental data, our technical team recommended the 4-72 Type Centrifugal Fan (Model 12A).

Why this specific model?

• Massive Volume Capability: According to our performance curves, the 12A model equipped with a 132kW motor delivers an impressive air volume of 69,881 to 97,813 m³/h with a total pressure of up to 4611 Pa. This was perfectly aligned with the client’s need for rapid air replacement in a massive space.

• Stable & Low Noise Operation: The 4-72 series is specifically engineered for high efficiency and a steady pressure curve, which drastically reduced the aerodynamic noise that was plaguing the factory floor.

The “Direct Manufacturer” Advantage: Customization

Because we design and manufacture entirely in-house, we didn’t just sell them an off-the-shelf product. We provided critical factory-direct customizations:

• Wear-Resistant Treatment: Knowing the transferring medium contained abrasive cement dust (strictly kept under the 150mg/m³ limit for optimal operation), we applied a specialized wear-resistant coating to the impeller to extend its lifespan significantly.

• Climate Adaptation: We ensured the motors were tropicalized to handle the humid Vietnamese climate, operating flawlessly under the maximum allowed gas temperature of 80°C.

The Results: Enhanced Efficiency and Zero Downtime

The installation of four customized POPULA 4-72 (Model 12A) centrifugal fans completely transformed the workshop environment:

• 35% Improvement in Ventilation Efficiency: The high-volume air circulation effectively cooled the workshop, creating a safer and more comfortable environment for the workers.

• Zero Unplanned Downtime: After 12 months of continuous operation, the fans have shown no significant wear and have maintained steady pressure without the extreme noise levels of the previous system.

• Cost Savings: By purchasing directly from a 100% source manufacturer, the client saved over 20% on procurement costs compared to local distributors, while receiving superior after-sales technical support.
