The client is a leading manufacturer of electric vehicle batteries operating within one of the largest EV battery production facilities in the United States. Their operations highlight the need for effective air filtration solutions that control contaminant gas emissions and support compliance with local environmental regulations.
Volatile organic compounds (VOCs), such as N-methyl-2-pyrrolidone (NMP), are heavily utilized in lithium-ion battery manufacturing. These compounds are essential for dissolving binder materials during electrode production but must be carefully controlled to ensure safe operation and regulatory compliance.
The client needed a solution capable of effectively removing VOC emissions before air was exhausted from the facility. Their team had previously been presented with an option that required a large, space-heavy system, an impractical fit given the facility’s layout and available footprint. When they turned to AAF, we conducted a detailed analysis of their process conditions and developed a compact, space-efficient approach tailored to their operational requirements.
AAF delivered a compact, high-efficiency system centered around two 7 x 12 ft (2.1 x 3.7 m) non-powered (passive) vertical Deep Bed Scrubber (DBS-V) units. To enhance performance and protect the media, the system also incorporated mist eliminators and particulate filters at the inlet.
Each DBS-V unit was engineered to deliver strong VOC removal while minimizing the required footprint, an essential factor given the client's space limitations. The scrubbers were filled with SAAFCarb media, AAF’s high-performing pelletized carbon designed for effective gas-phase adsorption. Additionally, VariCel MERV 14 high-capacity filters were included to provide extended-surface particulate filtration, supporting cleaner operation.
This customized vertical configuration enabled the client to achieve the required emission control performance without the space demands of a traditional, larger-scale solution.
The SAAF Deep Bed Scrubber-V delivers a complete gas-phase filtration solution with a high media-to-air ratio for demanding industrial environments. Built for mission-critical performance, its patent-pending sealing system locks final filters securely in place to ensure maximum protection and reliable operation.
The VariCel particulate filter provides dependable, long-term performance even in harsh operating conditions. Its open-header design prevents dirty air bypass, enhances handling safety, and supports efficient particulate capture for a wide range of HVAC and industrial applications.
SAAFCarb media is a high-quality pelletized activated carbon engineered to remove harmful and odorous gases from the air. Manufactured from a bituminous coal base and UL 900 Classified, it is ideal for applications involving chlorine, hydrocarbons, nitrogen dioxide, and a broad range of VOC contaminants.
