โครงการระบายอากาศห้างสรรพสินค้า POPULA โดยใช้พัดลมแบบแรงเหวี่ยง 4-72 ตัว
POPULA fan shopping mall ventilation project planning started from a typical commercial building problem: the mall’s basement service corridor and food-court back-of-house duct area had weak air exchange during peak operating hours. Warm air and mixed odors were difficult to discharge through the existing duct route, and the maintenance team needed a fan solution that could provide stable pressure for duct ventilation without turning the project into a complex reconstruction. POPULA reviewed the duct resistance, installation space and operating environment, then recommended a 4-72 centrifugal fan solution for general ventilation and air exchange.
POPULA fan shopping mall ventilation project application scenario
This type of application is common in shopping malls, large hotels, restaurants, public buildings and underground commercial service areas. Compared with a simple wall exhaust point, a mall ventilation route often includes elbows, rectangular ducts, dampers, grilles and longer air paths. The fan therefore needs more stable pressure than a direct axial exhaust fan can usually provide. The goal is to move normal indoor air through the duct network and improve air exchange in back-of-house areas without interfering with customer-facing spaces.
The 4-72 centrifugal fan was selected because the product family is designed for general ventilation, air exchange and cooling in factories, mines, large public buildings, restaurants, hotels and shopping malls. According to the product information used for this project, the handled medium should be non-flammable, non-explosive and non-corrosive air, with dust content not exceeding the stated limit and air temperature within the rated range. For this case, POPULA treated it as a commercial ventilation project, not as a fire smoke exhaust or high-temperature emergency system.
Why this 4-72 centrifugal fan product was selected
The main requirement was stable duct performance. In a mall basement or food-court service zone, the fan does not simply blow air into an open space; it must overcome resistance from ducts, bends, grilles and installation distance. A 4-72 centrifugal fan is suitable for this type of general ventilation because its volute housing and impeller design can provide a more useful pressure range for ducted air movement. This makes it a practical choice when the airflow path is longer or more restricted than a direct wall opening.
Noise and maintenance were also important. A commercial building cannot accept a solution that creates excessive vibration or makes daily operation difficult. The 4-72 series is positioned for high efficiency, relatively low noise, stable pressure and general-purpose ventilation. POPULA therefore recommended placing the fan in the mechanical area on a stable base, connecting it to the duct route with proper support, and leaving enough access around the motor, inlet and casing for inspection.
How the layout improved mall duct ventilation
The layout focused on three points: where air was collected, how it moved through the duct, and where the fan could be maintained safely. First, the collection points were adjusted around the service corridor and food-court back-of-house area where warm air and odor concentration were more noticeable. Second, the 4-72 centrifugal fan was connected to the duct route so the airflow could be guided through the intended path instead of leaking or circulating locally. Third, the fan was installed in a serviceable mechanical location rather than a crowded passageway.
POPULA also avoided oversimplifying the problem as “installing a larger fan.” A larger model can still perform poorly if the inlet is blocked, the duct path is too restrictive, or the outlet direction conflicts with building airflow. The project therefore considered duct size, elbow position, fan foundation, vibration isolation, control cabinet access and inspection space. This made the installation easier to manage for the mall’s facility team.
Actual value for commercial building operators
After the ventilation route was improved, the mall operator gained a more reliable way to manage air exchange in the service corridor and food-court duct zone. The value was not only stronger airflow; it was better control of where the air came from, where it moved and how the fan system could be inspected. For commercial buildings with long operating hours, this type of practical improvement can support a cleaner back-of-house environment and more predictable daily facility operation.
The project also gave the maintenance team a clearer equipment management structure. The 4-72 centrifugal fan was installed as part of a duct system with defined access points, so routine checks could focus on motor condition, belt or coupling status where applicable, casing condition, fasteners, vibration, duct leakage and air path cleanliness. This is important in shopping mall projects because the ventilation system must serve the building quietly and consistently while remaining accessible for service.
For similar projects, POPULA recommends collecting site details before final model selection: duct length, duct size, number of elbows, air volume requirement, installation room size, power supply, noise expectation, operating schedule and the type of air being transported. If the air contains grease, heavy dust, corrosive gas, high temperature or fire smoke requirements, the solution must be reviewed separately and matched with the correct product category.
As a ventilation fan manufacturer and project partner, ป๊อปปูล่า can support commercial building ventilation assessment, 4-72 centrifugal fan selection, duct layout review and installation planning. This POPULA fan shopping mall ventilation project shows how product selection and site layout work together to solve a real commercial ventilation problem with a practical, maintainable system.
