A global semiconductor company needed to improve energy efficiency in one of its newest manufacturing facilities in the U.S. In particular, the customer focused on a new fab with 5,800 4'x4' fan filter units (FFUs) with glass media filters installed. Within other cleanrooms in similar facilities supporting wafer manufacturing, the traditional glass media drove energy costs up due to its relatively high-pressure drop. Additionally, it was prone to damage during filter installation, maintenance, changeouts and storage.
To achieve the required energy savings in the new fab, AAF recommended:
AAF became involved through the general contractor overseeing the project, whose primary mission was to supply a more energy-efficient alternative at a competitive price. For the customer to fully understand the value that the MEGAcel II ePTFE ULPA membrane media filters provide, it was imperative that AAF work with them directly. AAF presented a total cost of ownership (TCO) summary to the customer to demonstrate the long-term energy, labor and material cost savings achieved by switching to membrane media ULPA filters. After reviewing the side-by-side comparison of glass vs. membrane ULPA filters, the customer purchased 5,800 MEGAcel II ePTFE ULPA filters for the facility.
Installation of all MEGAcel II ePTFE ULPA filters was completed in February 2022. Energy cost savings for this project are anticipated to be $1.3M over a five-year period. Additionally, whereas other facilities in their portfolio had been keeping hundreds of glass media filters in inventory due to installation damage, this facility eliminated the need to maintain a similar inventory due to the durability of the membrane media. This added benefit offers substantial labor and material cost savings, plus it frees up square footage.
A thorough air filter audit of your HVAC systems is the first step that AAF takes to provide you with HVAC energy analysis for cost savings. In this way, we identify how your filtration system can optimally perform. Contact us to find out more about lowering your HVAC cost.
This is an ultra-high efficiency and ultra-low resistance ePTFE membrane ULPA filter. ePTFE media provides superior benefits, including inert chemical properties, more uniform fiber distribution, and smaller fiber diameters and pore sizes. This reduces resistance, creating higher filtration performance to achieve substantial energy savings.
Targeted to your HVAC total cost of ownership, TCO Diagnostic provides clear insight to find the best filtration options and tailor to your specific needs for a comprehensive clean air solution – improving air quality, energy savings, and operational flexibility while reducing your life cycle costs.
