Founded in 1948 in Dallas, Texas, Butler Engineering began with Mayfair kitchen range ventilation hoods, laying the foundation for a dedicated team and strategy. Relocating to Mineral Wells in 1956 enabled expansion to meet housing market demands. Under the Ventamatic brand, the company grew rapidly, introducing innovative ventilation products such as Power Ventilators, Whole House Fans, and Portable Barrel Fans, broadening its reach across residential, commercial, and retail sectors. Now employing over 400 staff and spanning over 435,000 sq. ft. across six facilities, Ventamatic's products are available in 15,000+ locations throughout North America. Committed to quality, community, and ethical standards, Ventamatic unifies its offerings under Maxx Air®, continuing its legacy of enhancing comfort and energy conservation.
