Large air blowers (51, 131, and 273 CFM) are intended for use only in large commercial grade refrigeration units or walk-in coolers. This is because such blowers are large in size, and they generate considerable heat which residential grade and small commercial grade refrigerators simply do not have the cooling capacity to overcome.
