Abstract
Perfeccionamientos en los aparatos para filtrar una corriente de aire, a través de una batería o banco de filtros, dotados para comprobar la fuga de partículas de una granulometría predeterminada a través o alrededor de cualquiera de los filtros, caracterizados porque el aparato tiene capacidad de permitir la identificación inmediata de un filtro que adolece de fugas en el banco y porque el aparato comprende una carcasa adaptada para formar parte de un sistema de conductos de aire a través del cual pasa una corriente de aire.
