Designed for agricultural ventilation systems in poultry, dairy, and swine facilities, these kits allow installers and maintenance professionals to replace outdated fan components with reliable Multifan technology. Each kit includes a high-quality AC motor, impeller, and mounting system engineered to fit a wide variety of existing tube constructions.
