Product Description
🛡️
Explosion-Proof Design (Key Advantage)
The motor is completely isolated from methane-saturated air, eliminating the risk of ignition from electrical sparks. A friction copper ring design prevents sparking when the impeller contacts the casing, and the grounding system protects against leakage currents in accordance with coal mine safety regulations.
💨
High-Efficiency Ventilation
Powerful negative-pressure extraction effectively removes methane and hazardous gases from tunnels. High static pressure performance is suitable for long-distance tunnel ventilation, with a flat airflow pressure curve to adapt to various resistance conditions and extended air delivery range.
🔇
Low Noise & Eco-Friendly
A dedicated noise-reduction design keeps noise levels below industry standards, improving working conditions for miners. Complies with national environmental regulations and reduces health risks for workers.
⚙️
Reliability & Durability
Compact and rugged construction withstands harsh underground conditions. Designed for a service life of ≥5 years, providing ≥13,000 hours of safe operation before the first major overhaul. Easy maintenance with simple disassembly for repair.
