Solving dust extraction over a wide area

The build up of dust within the food industry can have serious detrimental effects not only on the product, but also to the health of the process operators and others working in the surrounding area. Often food and bakery processes are such that dust can be generated over a large area, thereby negating the ideal solution of extracting the dust at source.

To overcome this issue the Down Flow Booth from Flextraction Ltd has been engineered not only to contain, suppress and extract dust away from the breathing zone of the operator, but also to return clean air back into the work place. This is achieved by working on a re-circulatory airflow principle, whereby a constant, clean downflow of air is supplied from the ceiling via the HEPA (High Efficiency Particle Arrestor) filters.

Grilles in the lower rear wall capture airborne contaminants and filter the air via three stage filtration. This comprises of primary roughing filters, secondary bag filters and finally HEPA filters discharging over the operator's head, providing a nominal evenly distributed downflow of 0.5m/sec.

The Booth operates with inward airflow, ensuring airborne contamination cannot escape into the external environment and make-up air can only enter the Booth at low level.  Included within the booth are pressure indicating devices to monitor the performance of the extraction together with automatic control of the variable speed fans to maintain optimum operating conditions.   

The booths are of modular design and available in a variety of size from 2m up to 10m in width. They can be supplied with optional extras such as:

  • Internal / External 415v / 230v power supplies
  • Audible Filter Alarm
  • Bag disposal and Compactor
  • Integral vacuum unit
