01 Background
Project Background
A complex multi-scene project covering training workshops, teaching buildings and a canteen. High-pressure cabinets and centrifugal fans extract workshop dust, while water-cooled fresh air units supply classroom fresh air. The high-pressure cabinets carry air over long duct runs, the centrifugal fans continuously extract training dust, and the fresh air units improve classroom temperature and humidity. Powerful, durable equipment withstands long high-load operation, with zones focused on dust extraction, fresh-air cooling and canteen fume control respectively.
Fresh air, exhaust and fume-extraction equipment configured for classrooms, canteens and activity venues, based on on-site space and operating duty.

05 Installation Process
Installation Process
Silent cabinets are placed in teaching-plant rooms, fresh-air units on rooftops or platforms, and canteen exhaust cabinets connected to hoods and ducting, all on vibration-isolation bases with zoned ducting for easy service.
06 Results
Results
Continuous fresh air in teaching areas, markedly less stuffiness, smooth canteen exhaust without odor spread, and quiet operation that does not disturb teaching, clearly improving air quality and comfort.
