Abstract

An apparatus and a system is provided that may be utilized to determine air flow through an air filter and/or a plurality of air filters. The present invention utilizes a demonstration apparatus to illustrate the differences in air flow and air restriction between a plurality of different air filters and filtration media. The apparatus and system utilizes a common plenum which subjects the plurality of air filters to the same differential pressure. The air flows through a first side of the air filter and is measured on the second side of the air filter by utilizing a wind meter or similar device to gauge the amount of air flow velocity of the second side of the filter. Additionally, the apparatus and system utilizes a display means to illustrate the differing air velocity through the second side of the air filter.

Claims

1. An apparatus for measuring air flow through filtration media, the apparatus comprising:

a container means having at least a side portion, a top portion, and a bottom portion, the top portion including a top plate comprising a handle configured to pivot the top plate relative to the top portion;

an accommodation portion including at least including a first opening configured to accommodate a first air filtration media and a second opening configured to accommodate a second filtration media, wherein the first air filtration media and the second air filtration media within the accommodation portion, and wherein the top plate is configured to display the first air filtration media and the second filtration media;

one or more blowers configured to direct air flow through at least one of the first air filtration media or the second air filtration media; and

at least one anemometer to measure the air flow through at least one of the first air filtration media or the second air filtration media.

2. The apparatus of claim 1, wherein the accommodation portion holds a plurality of air filtration media including the first air filtration media and the second air filtration media.

3. The apparatus of claim 1, wherein the top plate extends away and allows access to the accommodation portion when in an extended position.

4. The apparatus of claim 1, wherein the apparatus has a plurality of anemometers connected to the accommodation portion.

5. The apparatus of claim 1, wherein the apparatus has a plurality of anemometers, each configured to collect air flow data from above at least one of the first air filtration media or the second air filtration media and report the results to a viewer.

6. The apparatus of claim 1, wherein at least one of the first air filtration media or the second air filtration media is a vehicle air filter.

7. The apparatus of claim 1, wherein the container means has at least one transparent portion configured to permit a viewer to observe an interior portion of the container means.

8. The apparatus of claim 1, further comprising:

a plurality of air filtration media is accommodated in the accommodation portion; and

a common plenum configured to subject each of the plurality of air filtration media to the same differential pressure.

9. The apparatus of claim 1, wherein a front portion and the top portion of the container means are constructed of clear Plexiglass™

.

10. The apparatus of claim 1, wherein the anemometer measures a total velocity exiting a plurality of air filtration media and displays the results of the total velocity on a display means.

11. The apparatus of claim 1, wherein the anemometer is positioned above at least one of the first air filtration media or the second air filtration media whereby upon air exiting the at least one of the first air filtration media or the second air filtration media, air velocity data is collected by the anemometer to determine velocity of exiting air from the at least one of the first air filtration media or the second air filtration media.

12. The apparatus of claim 1, wherein a plurality of anemometers are positioned in substantially the same position on the accommodation portion such that each anemometer is subject to a set of parameters including only the air flow velocity leaving each air filtration media.
