摘要：Article presents the researches performed in order to achieve an air filter based on the ultrasonic cavitation phenomenon. This filter can be used in purification of polluted air from the highly polluting processing technology of an industrial shop (paint shops, foundries, welding constructions, forging, etc.). Practical realization elements of ultrasonic filter based on cavitation phenomenon and experimental results are described and presented. Experimental researches have shown an increased efficiency of using this type of filter (retention of microparticles larger than 1.0 μm, smoke retention and increase of duration of filter operation more many years). Besides these, advantages of using ultrasounds in the pollutant air filtration and purification process and an ultrasonic filter designed are presented.
