Compressed air is costly and often in short supply in manufacturing plants. According to US company, Spraying Systems Co., their 707 and 727 series air control nozzles can cut the annual consumption of air by up to 55%, compared with open pipes, and reduce noise levels by up to 60%, depending on the model. Applications for the nozzles include surface drying, product cooling, air knife cutting, and material cleaning and conveying, in a broad range of industrial processes.
