As much as 20% to 60% of the energy used to operate compressed air systems is wasted! This is primarily due to operating more compressors than necessary, operating compressors in bypass and/or maintaining elevated system pressures. 

Well known is the fact that compressed air, stored at higher pressures, can provide a capacitance effect for sudden hign volume demands. Less known is that higher pressure storage, that is not properly controlled and managed, will result in not just the additional energy to compress to a higher pressure, but also significantly higher air consumption from all compressed air users!
