Explosion-Proof Design
KEY ADVANTAGE
The motor is completely isolated from methane-saturated air, eliminating the risk of ignition from electrical sparks. The friction copper ring construction prevents sparking when the impeller contacts the housing, and the grounding system ensures protection 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 characteristics are suitable for long-distance tunnel ventilation, providing extended air delivery range with a flat airflow pressure curve to adapt to various resistance conditions.
🔇
Low Noise & Eco-Friendly
Special noise-reduction design keeps noise levels below industry standards, improving working conditions for employees. Complies with national environmental regulations and reduces health risks for workers.
⚙️
Reliability & Durability
Compact, robust 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.
