Did you know that a single 3-mm hole consumes as much compressed air as a Super Air Knife model with a length of 152 mm (6″)? Additionally, an air knife offers a low noise level (below 70 dBA given an unobstructed blow-off path) and does not have a dead end (safety at work).

The amortisation period if you replace holes with optimised blow-off nozzles is less than 6 months.
