Model AH Acoustic Horn
Precision-Engineered Acoustic Cleaning for Industrial Dust Removal
EnviroCare’s Model AH Acoustic Horn is a precision-engineered device that produces high-pressure sound energy at low frequencies to effectively remove dust and particulate buildup from industrial equipment.
EnviroCare pioneered the application of sound energy for cleaning reverse air fabric filters, transforming what had been a hit-or-miss technology into a reliable, engineered solution. Today, EnviroCare remains the leader in custom acoustic cleaning systems. Applications include: reverse air fabric filters, electrostatic precipitators, spray towers, silos and bins, heat exchangers, fan housings and multiclone collectors. In addition to the AH-20 and AH-30 Series horns, EnviroCare designs and manufactures horn bells tailored to specific applications.
How The System Works
Sound Generation
A corrosion-resistant diaphragm cycles rapidly to create powerful pressure pulses at frequencies between 80–160 Hz.
Wave Amplification
Pulses pass through our uniquely designed horn bell, which amplifies sound energy to optimal cleaning power levels.
Dust Removal
High-intensity sound waves penetrate dust deposits, inducing vibrations that shear particles from surfaces without causing structural damage to concrete, steel, fabric or refractory linings.
