Our smallest horn used to fluidize material inside hoppers and bins or inside Boilers. Cleaning distance is up to 15' and up to 6' diameter. 220 Hz frequency, 149 dB Sound pressure level.

Acoustic horns are designed to produce low frequency, high volume sound waves for the purpose of moving dust or soot particles. In practice one or more horns are inserted into a vessel and the dust or soot particles are subjected to sound blasts frequently enough to not allow heavy deposits to form.

For successful acoustic cleaning several requirements must be met:

* The build up has to be dry and powdery.

* The interval between sound blasts must be short enough to ensure that a significant buildup of dust or soot has not occurred, and that the duration of the sound blast is long enough to fill the whole vessel and break the particles adherence. Usually the starting point for most applications is 10 second duration every 10 minutes.

* The horns require between 40-80 SCFM of air at 70-90 PSI. The volume and pressure must be at these levels or greater to ensure that the horns emit sound efficiently.

* The vessel the horns are being installed on, must be clean and free of deposits. The goal of the horns is to have a short enough interval to keep the vessel clean.
