Wide Range of Suitable Environments:
High-temperature or odorous workshops (e.g., heat treatment plants, foundries, plastic factories, aluminum profile factories, shoe factories, leather factories, electroplating plants, chemical plants).
Labor-intensive enterprises (e.g., clothing factories, assembly workshops, internet cafes).
Horticultural greenhouses and livestock farms for ventilation and cooling.
Locations requiring both cooling and humidity (e.g., textile factories such as cotton mills, wool mills, linen mills, weaving mills, chemical fiber mills, knitting mills, silk mills, and hosiery factories).
Warehousing and logistics facilities.
Types of Negative Pressure Fans:
Negative pressure fans are primarily categorized into two types based on their structural materials:
