Mine-use double-resistant positive pressure air duct utilizes seamless heat-sealing technology, offering long-distance air delivery. What is positive pressure and negative pressure? Positive and negative pressure are concepts related to airflow in equipment. Understanding the differences between positive pressure air ducts and negative pressure air ducts requires learning and practical application—it's not something that can be grasped by mere luck or a few touches.

Because recognition is truly important; it allows our products to receive favorable reviews. Differences in air ducts: Positive pressure air duct: one steel ring at both the front and the end. Negative pressure air duct: the frame is on the outside, typically one every 25 cm, totaling about 30-40. Extraction air duct: the frame is inside, made of spring steel frame, one every 10-15 cm, totaling about 66-100.

Types of air ducts: Air ducts are categorized by coated fabric material into rubber-coated negative pressure air ducts, plastic-coated negative pressure air ducts, and rubber-plastic-coated negative pressure air ducts.
