The challenge

The company was experiencing quality issues in the final stage of their process, which consisted of “blowing off” large blocks of cheese before being packaged and shipped to food processing companies.

They contacted Total Filtration Services to help determine a solution for their quality issues, as they were finding metal flakes on the blocks of cheese, which had already caused them to throw away a large batch of product. Failure to resolve this issue would result in thousands of dollars in wasted product, as well as damage to their brand reputation.

The TFS solution

After surveying the area of concern, TFS found the particles (metal flakes) were coming from the metal separators on the HEPA filters. Because the separators weren't necessary in this application, TFS proposed switching to a similarly performing filter without the metal separators. Due to strong relationships with manufacturing partners, identifying the replacement filter was a short process.


The results

The customer embraced the recommended solution to replace the existing HEPA filters with a new brand and model without the metal separators. The customer was satisfied to learn that the quality issue went away and that TFS brought a technical solution which solved a problem causing product loss costing $100,000. Shortly after resolving the quality issue, TFS was asked to supply the new customer with several other types of filtration products for applications throughout their facility.
