Blast Fans
Your Best In Value and Customer Support
55" & 72" Arctic Blast Fans
Our louvered fans provide quiet, energy-efficient operation and can reduce
heating and cooling costs by up to 50%. They help de-stratify air in winter,
improving airflow and preventing stagnant pockets. Designed for high airflow,
these corrosion-resistant fiberglass fans direct air to cow level, reducing heat
stress and boosting cow health, milk production, and pregnancy rates. Built
with balanced blades and durable hardware, they feature easy-to-maintain
quick-change belt drive motors and variable speeds for optimal control
and air circulation in barns, holding areas, and parlors.
