Food manufacturer doubles filter life with AAF filtration

How did AAF help a food plant lower filter changeouts?

The Filtration Situation

Every two weeks, a $15 billion food manufacturer was switching out filters on its main production air handling units – thanks to sugar particles from breakfast cereals plugging up the filters. The plant was using a competitor’s headerless rigid bag filter. AAF completed an audit to uncover solutions for helping reduce costs and maintenance hours.

The AAF Solution

AAF recommended replacing the plant’s current filters with the AAF DriPak® 2000 filter with a header.

The DriPak 2000 filter has a unique, ultrasonically welded pocket design to allow complete inflation and eliminate crowding and leakage. Reinforced pocket support frames eliminate flexing or buckling, even in turbulent operating environments.

Using DriPak 2000 filters with a longer pocket size would allow the plant to extend the time between changeouts. The customer agreed to install the DriPak 2000 filters in one of the six AHUs on a trial basis.

Total Cost Benefits

Switching to AAF DriPak 2000 filters extended the life of the filters from two weeks to five weeks — two-and-a-half times the prior service life. The results convinced the customer to replace all the existing filters with AAF's DriPak 2000. The result was product cost savings of $23,720 for the six AHUs.

Also, the plant calculated additional maintenance and freight savings using the new filters. That added up to a total cost benefit of $25,175 per year.
