Mist coolant spray

A rough sketch of the purchased spray, not to scale, is presented here. The spray operates based on venturi effect, where oil flows inside a tube within Loc-line and exits via an atomizer at the end, while compressed air fills Loc-line and escapes around the atomizer's opening. However, there's a concern that the compressed air leaks significantly through the Loc-line hose, creating an unpleasant noise during operation.
