PRIMASONICS® recommended the installation of an Acoustic Cleaner Model PAS-75 to be mounted on top of the hopper. The company took advantage of the Primasonics® new Rental Plan whereby by a customer may rent the acoustic cleaner on a monthly basis until they are fully satisfied with its performance. One month after installation the company was fully satisfied that the Primasonics® Acoustic Cleaner had totally eliminated the gypsum build-up problem within the hopper – and so proceeded to purchase the horn.
