Its positive pressure explosion-proof technology is leading in China motor industry. The motor can be made into two explosion-proof types: positive pressure shell type Expx and Expz. Expx explosion-proof type can be used in Zone 1 and Zone 2. Expz explosion-proof type is used in Zone 2.

These two explosion-proof types are suitable for explosive gas environments formed by the mixture of gas, steam or mist explosive gas and air in factories, and the ignition temperature is T1, T2, T3, T4 groups. Positive pressure shell type Expx can also be used for Class I equipment. This series of motors are made of excellent materials. Exquisite manufacturing technology.

It has the characteristics of small size, light weight, high power, high efficiency, low noise, small vibration, safe and reliable operation, convenient use and maintenance, energy saving and environmental protection.

The motor can be customized according to customer requirements to Nanyang brand, Wolong brand, Schorch brand, etc.
