WindJet Air Knives powered by energy-efficient regenerative blowers provide excellent performance in drying and blow-off operations and eliminate the need for costly compressed air. Operating costs can be reduced by as much as 95 percent when the packages are used in a wide range of operations including debris and dust blow-off, removal of excess water and moving products.

WindJet Air Knives feature a unique 1/8″ leading edge along the length of the knife to direct a consistent and controlled air stream that retains its integrity further downstream and eliminates spotting and blotching. The air stream produced by the knives entrains ambient air to increase the total volume of air and maximize drying and blow-off efficiency.

Unlike other blower types, the regenerative blowers included with the packages are rugged, reliable and require infrequent, minimal maintenance. Plus, no sound enclosure is needed because the blowers provide low noise operation. Each air knife package is customized for the application. Air knives are available in lengths from 6” to 36” and two air slot sizes, .040” and .060”. Regenerative blower assemblies are available from 5.5 to 30 HP. Packages include pressure relief valve, pressure gauge, air inlet filter, filter monitoring gauge, vibration dampener, fittings and mounting adapter.
