The Fogchina dust suppression system filters dust from the air in mining environments or on building sites. It is rotatable by 320 degrees horizontally and by 40 degrees vertically and has a reach of 200 metres. The searchlight simplifies operation at night. A form that tapers towards the back makes the device look less bulky and simultaneously increases the air outlet surface. It can be operated manually, automatically or via remote control using a cloud system.
