Industrial Dust Extraction Fan

A substantial volume of fine dust is produced in the industrial processes that grind, cut, crush or handle dry materials. However, the real danger is not limited to the visible dust. Rather, the most harmful particles are those floating fine particles that we can't see with the naked eye. Silica dust from stone and concrete, metal fumes from welding or machining, chemical powders from factories, combustible dusts from grains, wood, and plastics are all under occupational exposure limits (OEL) and environmental emission regulations. Somehow a dust extraction system fails to maintain the correct capture velocity in each collection hood or loses sufficient static pressure in the ductwork and filter units, then those harmful particles can release back to the work environment. This is a serious health risk for workers and also violates legal regulations and creates a major explosion risk as well.

Industrial Dust Extraction Fan is the main driving force in the entire dust collection process. Basically, it generates and maintains the required system static pressure. For this, easily overcome the combined obstructions or resistance of the exhaust ductwork, pickup hood, pre-separator (cyclone) and filter unit (e.g. baghouse, cartridge filter or wet scrubber). Those fans are operating on the dirty air side, they need to face the pressure of abrasive particles. A radial impeller can operate in this condition without clogging or rapid blade wear. Also we use a backward-inclined impeller for those who need to operate on the clean air side. It can work with high aerodynamic efficiency , reduce the noise level and provide a non-overloading power curve. Based on dust collection system architecture and according to local regulatory requirements facilities engineers can choose their unit.

The Industrial Dust Extraction Fan has the same airflow and static pressure as other exhaust fans. An exhaust fan is a core of dust collection systems. This unit is suitable for fine dust particles as micron level, not for large and heavy metals. It maintain static pressure over the system and VFD (Variable Frequency Drive) compatibility allows control of the speed based on system demand. We also recommend our ATEX-certified configuration for the combustible dust applications.
