Leakage cfm is high in many machinesArrest leakages in Loom machine periodically2,00,068₹9,10,309₹100002.5
Pressure setting in looms is high around 5.5 bar. Recommended for cotton is 4.8 to 5 bar and for polyester 5 to 5.2 bar.Adjust regulator so that 0.2-0.4 bar pressure can be decreased which will give minimum 3 cfm savings per machine.81,846₹3,72,399₹02.5
