Product Details
What Is a Ventilate Sandwich Panel?
This insulated panel incorporates an airtight return-air path and a low-level stainless-steel outlet, reducing external ductwork and system complexity. Metal or composite surfaces support clean airflow. It pairs with our FFU ceiling grid and cleanroom sandwich panel range.
Airflow Engineering — How It Works
FFU ceiling supply directs clean air downward toward filtered low-sidewall returns. This follows particle settlement and helps carry contaminants away from work surfaces.

Ventilate Panel vs Stainless-Steel Outlet
| Feature | Ventilate Sandwich Panel | Stainless-Steel Return Outlet |
|---|---|---|
| Core function | Unified airflow direction | Energy saving & condensation resistance |
| Material | Modular sandwich structure | Premium stainless steel |
| Key features | Air renewal, eliminates static electricity | Corrosion-resistant, clean appearance |
| Best application | General cleanroom workshops | Medicine, chemical industry, etc. |
At steady indoor loads, mixing return air with fresh air at the AHU can reduce cooling energy compared with conditioning 100% fresh air.

Technical Insights & FAQ
Where should the return air outlet be located?
Place outlets low in the wall to guide settling particles toward the return and away from the work zone.
At what height should the low outlet sit?
Keep the outlet’s upper edge below the approximate 0.7 m work-area line, with roughly 0.2 m floor clearance, to limit airflow across worktops.
How does this system prevent cross-contamination?
Fresh-air circulation and suitable return filtration help limit pollutant transfer between workshops.
How does it save energy?
The AHU mixes recirculated return air with fresh air, reducing the energy needed to condition an entirely fresh-air supply.
What are the main advantages of the modular ventilation panel?
The modular panel simplifies installation and cleaning, supports static control and directs dust toward the return through a space-saving internal air path.
Can it be customized for different industries?
Yes. We tailor panel size, outlet style and airflow capacity to room volume and cleanliness targets. Corrosion-resistant stainless-steel outlets suit pharmaceutical and chemical facilities.
