Fan blades help circulate warm and cold air in your kitchen equipment. When your fan blade breaks, your ovens will fail to get up (and maintain) high temperatures. But it's your refrigerators, coolers, and freezers that are more at risk. If your equipment can't maintain a cold environment, it'll put your product at risk for safety. Save yourself the cost of an expensive service visit, and swap out your restaurant equipment fan blades quickly and easily yourself.
