📌 Mining Negative Pressure Ventilation Duct φ600-10 Product Overview
The Mining Negative Pressure Ventilation Duct φ600-10 is a specially designed flexible exhaust hose for underground coal mine ventilation systems. It is intended for negative pressure air extraction, efficiently removing dust, harmful gases, and hot humid air from the working face to the surface.
The φ600 diameter fits most medium-sized negative pressure ventilation systems, often used for auxiliary roadway exhaust, temporary ventilation, and heading face negative pressure extraction systems.
✅ Mining Negative Pressure Ventilation Duct φ600-10 Key Features
-
Negative Pressure Design: Built-in reinforcement ribs or steel rings prevent collapse and deformation under suction.
-
Excellent Safety Performance: Flame-retardant and anti-static properties ensure safe underground operation.
-
Standard Length 10m: Fewer connection points for improved sealing and reduced air leakage.
-
Coal Mine Dedicated: Exclusively designed for mining exhaust systems (not for general engineering ventilation).
-
Compliance with China Coal Safety Standards: Test reports and technical certification available.
-
Multiple Connection Options: Quick coupling, sewn ring, plug-in type, or zipper connections.
