WHAT IS IT? The Model AD is an aeration pad or diffuser that is used to provide a means of introducing low pressure air into a dry bulk material that has become compacted due to settling. The air will help restore the material's natural ability to flow.
WHY IS IT NECESSARY? The Model AD aeration pad helps restore material flow without the sometimes damaging effects of vibration or more expensive and complicated flow systems. The pads use a minimum amount of air (typically 6.5 cfm at 3 psi).
