Efficient blowoff of zinc particles

Pneumatics & Hydraulics

January 2006 Pneumatics & Hydraulics

Galvanized steel sheet need to be cleaned of zinc particles during the final rolling operation. Initially an air manifold consisting of 42 mm open pipe was installed across the sheet, blasting it with compressed air at 550 kPa. While this scheme produced a satisfactory end product, both noise level and air consumption were unacceptably high.

Exair Model 6013 high velocity air jets were installed in the existing pipe nipples. Compressed air consumption was reduced by 30% and the noise level reduced to 90 dBA - a 300% reduction in sound, reduced compressed air consumption.

Companies looking for major cost saving opportunities on their production floors, chances are their compressed air systems are a good place to start. Energy is a substantial cost factor in most plants and compressed air is often at the top of the list. 'Air abuse' can be eliminated in a number of ways - plugging leaks, repairing or replacing valves and filters, cycling air where possible and replacing noisy, energy wasteful open jets with quiet and efficient air jets.
