The positive pressure explosion-proof technology utilized in this series is a leading innovation. The motor adopts a highly reliable ventilation and leakage compensation system to ensure maximum safety. Before startup, the system effectively replaces any explosive gas within the motor cavity; the device sends an interlocking signal only when it is safe to proceed.

During operation, the compensation system automatically maintains appropriate pressure in the inner cavity to prevent explosive gas from entering the shell. If the outlet pressure drops or normal leakage compensation cannot be guaranteed, the system automatically triggers an alarm or cuts power. This achieves a perfect combination of automatic control and comprehensive protection.
