Solutions
This plastic packaging workshop ventilation solution Ho Chi Minh City project was designed for a plastic packaging workshop in Vietnam where the main production problem was not a single hot corner, but a combination of heat from sealing and film-processing equipment, humid indoor air, and weak local exhaust near the machines. POPULA proposed a combined ventilation layout using DFS series large industrial ceiling fans for wide-area air circulation and DF series multi-wing centrifugal fans for localized ducted exhaust around key heat and odor sources.
Plastic packaging workshop ventilation solution Ho Chi Minh City application scenario
The workshop was used for plastic film packaging, heat sealing, and related light manufacturing operations. During long production hours, operators worked close to machines that released continuous heat. Because the building relied mainly on general wall ventilation and small local fans, airflow was uneven across the workshop.
In the production area, warm air tended to stay around the sealing and film-processing lines. Near some machines, the customer also wanted better removal of process odor and moisture-heavy air. Simply adding more small fans would not solve the issue, because the workshop required both large-space circulation and targeted extraction at the source.
The project therefore needed a practical ventilation solution that could improve overall air movement without rebuilding the workshop structure, while also giving specific machine areas a stronger exhaust path.
Why choose DFS industrial ceiling fans and DF series centrifugal fans
For this application, the DFS industrial ceiling fan and DF series centrifugal fan were selected as complementary products instead of competing options.
The DFS series large industrial ceiling fan is suitable for workshops with high ceilings and wide working areas. Its role is to move a large volume of air slowly and evenly, helping reduce stagnant zones and improving air circulation across the production floor. In a plastic packaging workshop, this is useful because workers are distributed across several machines, packing tables, and material handling areas.
The DF series multi-wing centrifugal fan is more suitable for point-based ventilation. It can be connected with ducts, hoods, or local exhaust points to move air from a specific machine area toward a controlled discharge path. For heat sealing machines, printing-related sections, or plastic equipment that requires local cooling or exhaust, the DF fan provides the pressure needed for a more directed airflow route.
By combining both products, POPULA avoided a one-size-fits-all approach. The ceiling fan handled workshop-wide circulation, while the centrifugal fan focused on machine-side ventilation where airflow resistance and duct connection mattered more.
How POPULA arranged the airflow layout and solved the problem
The proposed layout divided the workshop into two ventilation layers. The upper layer used DFS industrial ceiling fans installed above the main production zone. Their purpose was to keep air moving through the larger working area, reduce stagnant heat accumulation near the roof and machine aisles, and help distribute fresher air more evenly.
The second layer used DF series centrifugal fans for localized ventilation. Instead of trying to exhaust the entire workshop from one point, the system focused on the areas closest to heat sealing, film processing, and odor-generating operations. Local ducting and collection points were arranged near these sources so warm or humid air could be removed before it spread through the workshop.
This layout also considered practical installation conditions. The workshop needed to keep production running, so the solution avoided major civil work. Ceiling fans were positioned to cover the wider production area, while duct routes for the DF centrifugal fans were planned along existing walls and equipment lines where possible.
Actual value for the plastic packaging workshop
After the ventilation plan was applied, the workshop gained a clearer airflow structure. General circulation was no longer dependent only on wall openings, and machine-side ventilation was no longer treated as a broad-area problem. This made the system easier to understand, operate, and maintain.
For production managers, the practical value was mainly reflected in four areas:
- More even air movement across the main plastic packaging workshop
- Better local exhaust support near heat sealing and film-processing equipment
- Reduced stagnant warm and humid air around machine aisles
- A ventilation layout that could be installed without changing the entire building structure
This type of solution is especially suitable for factories in humid regions of Southeast Asia, where heat, moisture, and long operating hours often appear together. For similar packaging, printing, plastic processing, or light manufacturing projects, POPULA can review the workshop layout, identify heat and odor sources, and recommend a practical combination of large-space circulation and local ducted ventilation using POPULA fan products.
