Air cannon is a de-clogging equipment composed of two main elements : a pressure vessel (storing air pressure), and a triggering mechanism (high speed release of compressed air). They are permanently installed on silos, bins and hoppers walls for all powdery form of materials, thus preventing caking and allowing maximum storage capacity.Air cannons do not require any specific air supply. Available plant air is sufficient with a minimum of 4 bars air pressure (60 psi), although 5 to 6 bars are preferred for better results (75 to 90 psi). The average air consumption is moderate, and depends on the number of firing per hour, size of the pressure vessel, and number of air cannons installed. For instance, a 50-liter air cannon consumes 0.60 Nm³/hour at 6 bars air pressure (90 psi), with 2 firing per hour.
