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 difference between positive pressure air ducts and negative pressure air ducts requires learning and application—it's not something you can grasp by mere luck or a few touches.

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

Types of air ducts: Based on coated fabric materials, air ducts are categorized into rubber-coated negative pressure air ducts, plastic-coated negative pressure air ducts, and rubber-plastic-coated negative pressure air ducts.

Packaging and storage of positive and negative pressure air ducts:

1. Compress the negative pressure air duct axially to less than 700 mm in length, secure it with ropes or cloth strips at 3-4 points, and then package it with high-quality materials;

2. During transportation, avoid mechanical impact, friction, direct sunlight, and rain;

3. Negative pressure air ducts should be stored in a well-ventilated warehouse. Stacking height should not be excessive to avoid affecting quality. Used air ducts should be rinsed, air-dried, and then folded for storage. Avoid contact with substances that damage rubber and plastic, direct sunlight, and rain. Storage temperature should be between -15°C and 35°C, with relative humidity between 45-75%, and kept at least 1 meter away from heat sources.
