Abstract
A fan filter device with one or more fan blades substantially comprising a filter media coated or impregnated with a fluid for removing particulates, such as dust and other pollution, from airflow in a wide variety of environments. The fluid has evaporation and viscosity characteristics suitable for maintaining the filter media in a wet condition at the desired speed and temperature of operation.
Description
- The present application claims priority to and the benefit of the filing date of U.S. Provisional Patent Application Ser. No. 61/329,621 filed Apr. 30, 2010, which is incorporated herein by reference.
- The present invention pertains to the filtering of air by fan rotors or fan blades constructed air filtering material to eliminate or reduce pollution from airflow.
- Air pollution can be a detriment to both persons and machines. Polluted air negatively affects health, and it can clog or overheat machines and electronics. Improved systems are needed to filter out air pollutants.
- To answer this need, in one embodiment of the invention a fan blade comprises an air filter material to remove pollutants from the airflow. In embodiments, the air filter material may be coated or impregnated with a moistening substance, such as fluid compositions, to provide improved filtering results, including binding particulates, such as fine and ultrafine dust particles, to a fan blade individually or together with other fan rotor components made of filter material.
- In certain embodiments, fan blades comprised of filter material may be individually replaced as part of the fan rotor. In other embodiments, a combination of fan blades together with one or more of the hub and other fan rotor components coupled to such blades may all be constructed of filter material.
- In embodiments of the invention, the filter material components of the fan may be removed for cleaning or may be disposable and replaceable. The filter material may also be recyclable.
- The particular features and advantages of the invention as well as other objects will become apparent from the following description taken in connection with the following drawings in which:
-
FIG. 1 is a front perspective view of one preferred embodiment of the fan filter device of the present invention. -
FIG. 2 is a rear perspective view of the fan filter device ofFIG. 1 . -
FIG. 3 is a front perspective view of an alternate preferred embodiment of the fan filter device of the present invention. - As illustrated in
FIG. 1 , the device of the present invention is directed to a fan filter device orfan 10 having a plurality offan blades 11 spaced about the periphery of therotor body 12. In the present invention, one or more of said plurality offan blades 11 substantially comprise or are substantially made of a porous filter material or filter media that filters pollution (particulates and the like) from airflow. Alternately, one or more selected components of therotor body 12, such ashub 23,peripheral side wall 13,top 14, orhub surfaces 15 connectingside wall 13 andtop 14, may also be substantially made of filter media that filters pollution from airflow. - Airflow may include intake, exhaust and circulating air. A
fan filter apparatus 10 of the present invention may be sized to large or small environments, ranging by non-limiting examples to afan 10 that filters air to/from a room or building to afan 10 that filters air in small electronics (not shown) such as computing devices and office machines. - In one embodiment, a
fan device 10 of the present invention includes fan blades 11 (or, including thefan blades 11, one ormore components rotor body 12, or the entire fan 10) made of a filter medium substantially comprising polyethylene. A polyethylene having PE, XM-1834, Hydrophop, pore size from 180 to 320 μm, pore volume of less than 35% has been found suitable for use in the present invention. In one preferred embodiment, such polyethylene is manufactured by Porex Technologies GmbH (Aachen, Germany). - The filter media of the
fan blades 11, and, as desired, selectrotor body 12components surfaces select surfaces rotor body 12components - A fluid for maintaining the filter media in a wet condition may be coated or impregnated in the filter media to contact, bind and filter particulates and other pollution. Preferably such fluid keeps the filter media of the
fan 10 wet for longer periods of time, such as not drying out for several months or years, even during substantially continuous use throughout such period. The aforementioned polyethylene filter media construction has been found preferable for maintaining thefan blades 11 in wet condition. - In one embodiment, a preferred fluid for maintaining the filter media in a wet condition comprises a silicon liquid, such as XIAMETER® PMX-200 Silicone Fluid, from 5,000 to 60,000 cSt (manufactured by Dow Corning Corporation (Midland, Mich.)). However, depending on the speed of the circulating blades 11 (RPMs) and/or temperature of the airflow environment, other liquids with different evaporation and viscosity characteristics may be more suitable to a particular filtering application.
- The viscosity of the fluid is important to avoid the fluid from draining from the filter media of the fan blades 11 (and/or other
selected components other rotor body 12components - In other embodiments, special-purpose liquid chemicals for reacting with gases or other compounds in an airflow environment may be provided on the filter media of the
fan blades 11 and any applicable selectedrotor body 12components fan blades 11 and applicable selectedrotor body 12components - The lifetime of the
fan filter 10 depends on the amount of pollutants in the air and the volume of particles which build up on therotor body 12,other components blades 11. As the fan blades 11 (and selectedrotor body 12components hub 23 and/or other selectedrotor body 12 components) are removable for cleaning and re-application of fluid in alternate embodiments of the invention, such asfan blades 11 being releasably affixed to thehub 23. - In another embodiment, the
filter media components fan 10, or theentire fan 10 itself, may be disposable or recyclable. In some embodiments, thefan 10,fan blades 11 and/orother fan components fan blades 11 andcomponents -
FIG. 2 illustrates a rear perspective view of a preferred embodiment of thefan 10 of the present invention.Hub 23 ofrotor body 12 may be adapted to accommodate any conventional means for rotatingfan 10 as is well known in the art. -
FIG. 3 illustrates a perspective view of an embodiment of thefan filter device 30 of the present invention suitable for use in connection with small electronics, such as computing devices or office machines (not shown).Fan rotor body 32 offan filter device 30 is carried by ahousing 33 comprising one ormore plates such plate more screw holes 36, or other conventional fastening means, such as being sized to slide within a preformed slot (not shown), or the like. - In another embodiment, one or both
plates - While the invention has been described with reference to the structures and methods disclosed, it is not confined to the details set forth, but is intended to cover such modifications or changes as may fall within the scope of the following claims.
