Upgrading filters to be ATEX approved

  • Bag filter:

  • SimPact 4T-R
  • Application:
  • Aspiration
  • Country:
  • Denmark
  • Product:
  • Potato flour
  • Filter type:
  • 2 pcs. JM 52/30-04 4T-R
  • Filter area, total:
  • 137.28 m²
We supplied our potato flour customer in Denmark with two filters for their factory in 2003. They asked us to upgrade and reconfigure the filters to ensure compliance with the ATEX Directive.

The challenge

As potato flour is an organic, carbonaceous material and potentially explosive, the customer needed to comply with the ATEX Directive (which covers equipment and protective systems intended for use in potentially explosive atmospheres). We conducted a pressure-shock resistance calculation of their existing filters. This included assessing and defining the operating conditions – and calculating the pressure relief – of the filters.

The value

We converted the filters to JM 52/30-04, type 4T-R. They are now designed to operate as aspiration filters with a pressure relief based on a calculation of Kst=91 bar·m·s-1 and Pmax=0.8/2 bar. We supplied the filters in addition to support the customers efforts to issue a CE compliance declaration for the product line.
