AAF works with Panasonic's Tesla EV Battery Production Facility

AAF helps find air filtration solutions to control the emission of contaminant gases, ensuring compliance with local regulations.

The Filtration Situation


Volatile organic compounds (VOCs), such as N-methyl-2-pyrrolidone (NMP), are widely used in the production of lithium-ion batteries. These compounds play a key role in dissolving binding materials used in electrode manufacturing.

The client needed to remove VOC emissions from the air before exhausting from the facility. Initially, our competitor proposed a large system that consumed significant facility space. When the client consulted AAF, we developed an alternative, space-efficient solution tailored to their requirements after comprehensive analysis and discussions.

The AAF Solution


AAF provided two 7 x 12 ft (2.1 x 3.7 m) non-powered (passive) vertical Deep Bed Scrubber (DBS-V) units, and a large capacity system equipped with mist eliminators and particulate filters at the inlet. The package also included SAAFCarb media, featuring high-performing gas-phase pelletized carbon, and the VariCel Merv 14 particulate filter, renowned for its high capacity, extended surface, and supported filtration capabilities.

The DBS-V was specifically designed to minimize job site footprint while excelling in VOC removal. To reduce the footprint of the equipment on site, AAF proposed customized vertical deep bed scrubbers (DBS-V units) with a large amount of our high performing SAAFCarb Media along with mist eliminators at inlet.

The Results

Testing was conducted by a third-party laboratory to evaluate the performance of the chemical media in both DBS-V units. Three trials were performed at each outlet to ensure consistent and reliable results.

The results demonstrated outstanding VOC removal efficiency, achieving greater than 99.9% performance across all tests. The SAAFCarb media, selected for its high adsorption capacity and proven reliability, effectively removed the VOCs from the exhaust stream.

These results confirm that AAF’s deep bed vertical scrubber (DBS-V) using our SAAFCarb gas-phase media provides highly effective VOC control, ensuring clean air discharge and validating its suitability for demanding industrial applications.
