Camfil Data Center Expert Council Releases New Video - How Low Resistance Air Filters Save Energy in Data Centers

Virtual Masterclass by Adam Wiggins, Data Center Segment Manager, Camfil USA

Camfil USA, a leader in clean air solutions, continues to provide valuable insights into how advanced air filtration technologies can contribute to significant energy savings in data centers. In a recent video interview, Adam Wiggins, Data Center Segment Manager at Camfil USA, discusses how filters with low resistance to airflow require less fan energy to maintain the required volume of air in HVAC systems.

Engineering Innovation for Energy Efficiency

During the interview, Adam explains that all air filters exhibit some resistance to airflow, and as a filter loads with dirt, it becomes more challenging for air to pass through. However, innovative engineering techniques have allowed Camfil to design filters with less drag as air moves through and with greater media surface area that results in reduced airflow resistance while still effectively capturing contaminants. This approach is akin to advancements in the aviation industry, where reducing drag on aircraft has been a critical focus.

Adam highlights the impact of these low-resistance filters in HVAC systems equipped with variable frequency drives (VFD). "In a VFD system, the fan speed increases as the filter resistance rises to maintain the required airflow, leading to higher energy consumption," Wiggins explains. "However, a filter designed to operate at a lower resistance can supply the necessary air volume with a slower fan speed over a longer period, ultimately saving energy." Watch the video.

Camfil's latest video series explores various aspects of energy efficiency in data centers, emphasizing the importance of air filtration in reducing operational costs and environmental impact. The easy-to-digest videos are available on Camfil’s YouTube channel, providing essential insights for facility managers, engineers, and decision-makers in the data center industry.
