Overview

Antistatic Mining Negative Pressure Ventilation Tubing, also known as the antistatic mining negative pressure ventilation hose, is a high-performance ventilation conduit designed specifically for high-risk operating environments such as mines and tunnels. Its core mission is to safely, efficiently, and reliably deliver fresh air to the work surface while powerfully extracting pollutants such as dust, harmful gases (such as methane), and smoke. This fundamentally improves underground air quality and protects the lives and health of miners. It is an indispensable key piece of equipment in modern mine safety production systems.

Product Features

Excellent anti-static properties (surface resistivity typically within the 10³ to 10⁶ Ω range) fully comply with MSHA standards, providing crucial safety assurance for operations in gas environments.

Its built-in high-quality steel spiral supports offer exceptional negative pressure resistance, capable of withstanding negative pressures from -2500Pa to even higher while maintaining its shape, ensuring uncompromised ventilation.

Lightweight and Flexible: Despite its sturdy structure, the tube itself is lightweight and extremely flexible. It can be easily bent and coiled to navigate complex underground obstacles, significantly reducing the labor intensity of transportation, installation, and recovery, saving time.

Wear-Resistant and Durable: The outer material exhibits excellent aging, acid, alkali, and abrasion resistance, ensuring a long service life even in harsh underground environments, offering excellent value for money.

Efficient Ventilation: The smooth interior provides an extremely low drag coefficient. With a main fan of equivalent power, it can deliver a greater volume of fresh air over a longer distance, helping to reduce fan energy consumption.
