● Long air delivery distance with large airflow: Air volume reaches above 18,000 m³/h, satisfying ventilation requirements of large-area workshops
● Excellent air purification: Integrated ventilation, air exchange, purification and odour removal. It exhausts odorous, dusty and stuffy indoor air and brings in fresh outdoor air. Filtration efficiency for dust particles larger than 1μm exceeds 80%
● Remarkable cooling performance: Achieves temperature drop of 4℃ to 10℃ with rapid cooling response
Functional Section Introduction
● Pre-filter section: Uses non-woven panel pre-filter to preliminarily capture large particles in fresh air, meeting internal hygiene requirements and reducing the load on medium filter section.
● Medium filter section: Uses non-woven bag filter to remove secondary dust generated through ducts and the unit, further reducing filter load and improving supply air cleanliness.
● Fan section: Adopts low-noise centrifugal fan with low sound level and high static pressure. Variable frequency control is available upon customer request.
● Cooling coil section: Cooling coil face velocity ≤2.5 m/s, constructed with hydrophilic flat fins, delivering good heat transfer performance while resisting dust accumulation and bacterial growth, without water carry-over.
● Heating section: Hot water heating, steam heating or electric heating available. Electric heating adopts smooth stainless steel tubes without fins, featuring corrosion resistance, low dust accumulation and easy cleaning.
● Humidification section: Dry steam humidification is available, ensuring no residual water inside the humidifier after shutdown to eliminate bacterial growth.
