The YORK® CLD belt driven unit offers a wide range of sizes with capacities extending over 17,000 CFM. Units are low and inconspicuous, with a unique design that features motor mounting beside the wheel rather than atop the wheel. Large wheels turning at moderate speeds provide quieter operation and airstream cooling for the motors and bearings. Units float on vibration isolators. Ball bearing motors, sheaves, belts and self-aligning ball bearings are all standard brands of national manufacturers. All components are selected for durability, efficiency and value.
