Overpressure

  • The fan which extracts and transports the chip loaded air is installed before the filter,deduster or dust extraction under overpressure.
  • Dirty air fans rarely reach an efficiency factor over 50%.
  • The use of dirty air dedusters is not allowed in commercially used working places, because in the case of slightest leakage the dusts are blown immediately into the working range.
  • In a business, a stationary dirty air filter unit is only allowed to be installed and used in a separate filter room.
