Wallner Expac is a 100% employee-owned company and North America’s largest manufacturer of light gauge expanded metals for filter media backing.

In 1975 we introduced expanded metal as a replacement for the more expensive welded wire used in pleated filters. This innovative solution positioned us as leader in the filtration industry.

After much R&D and listening to our filtration customers' feedback, Wallner Expac introduced X-Mesh®. It’s a patented light-gauge expanded metal specifically developed for filter media backing that is favorable for pleating, and is the industry standard for residential, commercial, and industrial applications.

THE X-MESH ADVANTAGES
◊ U.S. Patent No. 8,696,781
◊ Optimum filter performance as a result of pleat uniformity
◊ Improved airflow through a larger area due to strand reduction
◊ Increasing the strands by over 15% results in a stronger pleat back
◊ Consistent pleat height increases contact points between the die cut and the filter media
◊ Innovative design increases structual stability
