1. A smoke evacuation assembly comprising:
a filter;
a pump comprising a sealed positive displacement airflow path and an outer shell;
a motor engaging the pump and comprising an outer shell;
a first housing at least partially surrounding the filter and encapsulating the pump and the motor such that the pump and motor are surrounded on all sides by walls of the first housing;
a second housing encapsulated within the first housing such that the second housing is surrounded on all sides by the walls of the first housing, the second housing encapsulating the motor and the pump therein such that the motor and pump are surrounded on all sides by walls of the second housing, the second housing being separate and distinct from the outer shells of the pump and the motor; and
one or more vibration absorption mechanisms, the second housing being mounted to an interior surface of the first housing with the one or more vibration absorption mechanisms disposed therebetween.
