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 a filtration media, the apparatus comprising:

a container having at least top portion and at least a transparent side area;

an opening for accommodating an air filtration media which is removably placed into the opening and whereby a plurality of air filtration media utilizes the same opening on the container;

at least a blower to directing air flow through the air filtration media;

at least one anemometer positioned above the air filtration media to measure the air flow through the air filtration media.

2. A system of measuring air velocity, the system comprising:

a container having a side and a the top portion that are transparent;

at least an opening on the top portion of the container;

a top plate hinged to the top portion of the container wherein the top plate may extend away and allow access to the opening;

one or more blowers contained within the container to create air flow;

at least an a plurality of air filter media placed in the opening on the top portion of the container; and

a plurality of wind meters associated and positioned above with the at least one air filter, each of the plurality of air filters.

3. The system of claim 2 further comprising:

a common plenum contained within the container means to subject the air filter filters to the same differential pressure.

4. The system of claim 2 wherein the wind meters are positioned above the air filter whereby upon exiting the air filters, air velocity data is collected by the wind meters to determine velocity of exiting air from the air filters.

5. The system of claim 2 wherein the wind meters display the results of measured air velocity through the air filter.

6. The system of claim 2 wherein the wind meters display the results of the measured air velocity through the air filter utilizing a display means.

7. The system of claim 2 wherein the system may be connected to a computer terminal whereby the computer terminal graphically displays and prints a copy of the collected air velocity data from each of the air filter.

8. The system of claim 2 wherein the at least an plurality of openings on the top of the container accommodates a plurality of air filters whereby the air filters are removably placed into the plurality of openings and further wherein the air filters are interchangeable the opening with any of the plurality of openings.
