Negative Pressure Ventilation Duct φ600-10

📌Negative Pressure Ventilation Duct φ600-10 Product Overview

The Mine Negative Pressure Ventilation Duct φ600-10 (with 4×4 m fabric panels) is made from premium flame-retardant, anti-static PVC knife-coated fabric reinforced with high-strength polyester filament. It is manufactured using high-frequency heat welding or double-thread sewing to ensure excellent airtightness and durability.

Specially designed for underground coal mine exhaust systems, this negative pressure duct is used to extract methane gas, harmful gases, dust, hot and humid air from the heading face, coal mining face, or auxiliary roadways—ensuring a stable and safe working environment.

The fabric is cut into single panels of 4m × 4m, which reduces seams, improves structural strength, and enhances airtightness—ideal for heavy-duty negative pressure ventilation systems in coal mines.
