Remarks:
1, high-pressure water mist in a high-pressure pump power source, which is different from the traditional high-pressure compressed gas to provide a power source in the form of high-pressure water mist bottle (also known as group-type).
2, the high-pressure water mist and low pressure water mist essential difference. In the low-pressure water mist with water spray, water spray are powered centrifugal pump, the system pressure in 2MPa principle of fire, system is still the traditional technology.
