A filter assembly configured for acoustic dampening for use with compressor assemblies such as oxygen concentrators including a compartmented housing member having an inlet opening, an outlet opening, a filter member, and a plurality of noise attenuating members positioned and located therewithin. The configuration of the compartmented housing member in conjunction with the positioning and location of the filter member and the noise attenuating members therewithin all contribute to absorb and dissipate any sound waves generated within the housing member due to air flow movement therethrough. This substantially reduces and minimizes noise associated with the present filter assembly.

Filter assembly with noise attenuation

A filter housing assembly including a substantially frusto-conical shaped housing member having an open end portion and a substantially closed dome shaped portion, the housing member being adaptable for receiving a filter member therewithin and having at least one opening extending through the dome shaped portion for allowing air to enter therewithin. A first end cap member adaptable for engaging one end portion of a filter member is receivable within the housing member, and a second end cap member adaptable for engaging the opposite end portion of a filter member is engageable with the housing member. The second end cap member includes an opening for allowing air to exit the housing member. The housing member includes a centering mechanism engageable with the first end cap member for facilitating centering of the filter member within the housing member when the first end cap member is positioned within the housing member.
