ABSTRACT:
Embodiments herein comprise a compact dust abatement apparatus that includes at least one manifold shaped to fit next to a belt or drum of a printing engine, at least one blower/fan positioned within the manifold, and at least one air duct connected to the manifold. The manifold has a vacuum opening adjacent the belt or drum and an exit opening where the air duct connects to the manifold. The blower is positioned inside the manifold, between the vacuum opening and the exit opening, such that the blower draws air and particles from the vacuum opening toward the exit opening. Thus, the blower creates a vacuum at the vacuum opening. The air duct directs air and particles from the manifold to a location away from the sensitive components. The inclusion of the blower inside the vacuum manifold provides for compactness without sacrificing performance.
