VB vibrating bin aerators combine product aeration under pressure up to 6 bar with slight vibration on silo walls. The aerators improve mass flow of powders and granular materials without damaging silos. Compressed air is introduced through a silicon lip adhered to the silo wall. Varying operating pressure from 2 to 6 bar changes the vibration intensity of the silicon lip. Air consumption is low due to interval operation up to 5 seconds.
