Abstract: A method and system for treating objects, the objects are conveyed through a treatment cabin and treated in a treatment space. During treatment solvents are released. Cabin air flows through the treatment space, which absorbs solvents and is discharged as process air from the treatment space. At least one proportion of the process air charged with solvent is recycled in the treatment space and at least one proportion of the process air can be discharged as exhaust air. Fresh air is fed to the treatment space, which contributes to the cabin air, such that the cabin air includes a circulating air proportion and a fresh air proportion. The solvent concentration is captured in the cabin air and/or in the process air and/or in the exhaust air and the circulating air proportion and the fresh air proportion of the cabin air are regulated as a function of the captured solvent concentration.

Abstract: A synthetic jet driven cooling device includes at least one synthetic jet actuator to generate and project a series of fluid vortices.

The air amplifier includes an air intake oriented perpendicular to the connecting pipe and an air outlet positioned opposite the air intake, with a venturi section positioned between the air intake and air outlet that has a diameter smaller than the air intake diameter. A low pressure region in a center of the venturi section entrains a surrounding air in through the air intake to generate a secondary air stream that combines with the primary air stream to generate a combined air flow that flows through the venturi and exits the air outlet.
