Abstract
A unitary rigid filter that performs multiple contamination control functions within an enclosure for sensitive equipment (e.g., disk drives). The filter incorporates recirculation and adsorbent filtration, along with optional inlet and diffusion functions in a unique rigid filter construction.
Claims54
A filter adapted for removing particulate and vapor phase contaminants from an enclosure comprising:
- a rigid frame comprising a first end having an opening and a second end having an opening and at least one side, the rigid frame defining a volume therein;
- an extension extending adjacent to said rigid frame, the extension including at least one opening therein;
- at least one first filter media covering the opening in the first end and at least one second filter media covering the opening in the second end, thereby enclosing said volume within the rigid frame to form a chamber;
- at least one adsorbent located within the chamber;
- and
- at least one third filter media covering the at least one opening in the extension.
An article comprising a filter adapted for removing contaminants from an environment comprising:
- a rigid frame having four sides, a first open end and a second open end, the rigid frame defining a volume therein;
- an extension extending in a parallel plane to at least one of the first open end and the second open end, the extension having an opening therein;
- at least one first filter media covering the first open end and at least one second filter media covering the second open end, thereby enclosing the volume within the rigid frame to form a chamber;
- at least one adsorbent located within the chamber;
- at least one third filter media covering the opening in the extension;
- and an inlet in one of the four sides with a diffusion tube located over the inlet;
- whereby when the filter is located within the enclosure so that the diffusion tube lines up with a breather vent hole in the enclosure, the filter is capable of removing contaminants from air entering the environment and contaminants which are present within the enclosure.
A filter adapted for removing particulate and vapor phase contaminants from an enclosure comprising:
- a rigid three-dimensional frame having substantially the form of a parallelogram comprising:
- a first open end and a second open end, each opening having a top edge, a bottom edge and two side edges;
- a bottom, two sides each having an opening therein and a top having an opening therein connecting the two open ends;
- and a frame section having an opening therein bisecting the rigid frame and extending from the lower edge of the first open end to the upper edge of the second open end;
- at least one first filter media covering the first open end and at least one second filter media covering the second open end;
- at least one third filter media covering the opening in the bisecting frame section and at least one fourth filter media covering at least a portion of the sides which connect the side edges of the open ends so as to create a chamber below the bisecting frame section;
- and
- at least one adsorbent located within the chamber.
A filter adapted for removing particulate and vapor phase contaminants from an enclosure comprising:
- a rigid frame comprising a first end with an opening and a second end with an opening and at least one side, the rigid frame defining a volume therein;
- an extension extending adjacent to said rigid frame, the extension including at least one opening therein;
- at least one first filter media covering the opening in the first end;
- at least one adsorbent located within at least a portion of said volume;
- at least one second filter media covering the adsorbent to contain the adsorbent within at least a portion of said volume;
- and
- at least one third filter media covering the at least one opening in the extension.
