With an airfoil style five-blade design, these fans work hard to circulate efficiency and positively impact many factors within your facility. They balance the internal environment with a gentle mass of air or “floor jet,” which creates a more even temperature to protect product integrity and prevent potential product spoilage. Additionally, your employees will enjoy a more comfortable working environment, your products will maintain a steady temperature and moisture will be reduced in the air, keeping your floors drier and safer.
