Cleaning sheet steel with air jets
January 2007
Pneumatics & Hydraulics
The problem: galvanised steel sheets must be cleaned of zinc particles during the final rolling operation. An air manifold consisting of 42 1/8" (3,2 mm) open pipe nipples were installed across the sheet, blasting it with compressed air at 80 psig (550 kPa). While this scheme produced a satisfactory end product, both noise level and air consumption were unacceptably high.
The solution: EXAIR MODEL 6013 High Velocity Air Jets were installed in the existing nipples. Compressed air consumption was reduced by approximately 30% and noise level reduced to 90 dBA - a 300% reduction in sound pressure level.
Comment: if you are looking for major cost saving opportunities on the production floor, chances are your compressed air system is a good place to start. Energy is a substantial cost factor in most plants and compressed air cost is often at the top of the list. 'Air abuse' can be eliminated in a number of ways - plugging leaks; repairing or replacing faulty valves and filters; cycling air whenever possible; and replacing noisy, energy wasteful open jets with quiet, energy efficient EXAIR Air Jets.
