Calculation Example:
For a computer room with area S=60(m²), ceiling height h=3(m), and occupancy n=10(persons):
If calculated based on fresh air volume per capita, taking q=70(m³/h) per person:
Fresh air volume Q1 = n·q = 10 × 70 = 700 (m³/h).
If calculated based on air changes per hour (ACH), taking p=5 (times/h):
Fresh air volume Q2 = p·S·h = 5 × 60 × 3 = 900 (m³/h).
Since Q2 > Q1, Q2 (i.e., 900 m³/h) is adopted as the parameter for equipment selection.
The performance data below represents our standard model series. However, as a specialist manufacturer, we understand that every project is unique.

The fresh air ventilator is an innovative environmental appliance designed to ensure a continuous supply of clean, oxygen-rich air by mechanically forcing the circulation of fresh air indoors. It forms an independent air exchange and purification system that simultaneously expels indoor pollutants when treating incoming fresh air through processes such as filtration, heating and oxygen enrichment.
With its high-efficiency internal heat recovery system and various types options, this ventilator is ideal for residential, commercial and industrial spaces ranging from15 m² to 1100 m². It works quietly, consumes low energy, and requires minimal maintenance, making it a cost-effective solution for improving indoor air quality and energy savings.

To ensure safe delivery and smooth installation, every fresh air ventilator is carefully packaged with proper packages. The ventilators are typically shipped fully assembled, allowing for quick setup at the project site. To prevent moisture, damage and handling wear, every ventilator is wrapped in waterproof protective film and stabilized with strong wooden pallets or reinforced crates.
We provide flexible packaging solutions according to customer requirements including custom logos, export-grade reinforced crates, and stackable layouts for optimized container loading. The packaging is specifically designed for international shipping by sea, air or land to ensure the maximum safety and space efficiency. Every shipment includes a packing list, detailed installation manual, and user-friendly handling instructions to support smooth and accurate on-site installation.
