Abstract
Air purification or filtration unit having a triangular housing, with the open front face being the hypotenuse of the triangle. The unit is particularly adaptable for use with conventional sized high efficiency particulate air, or HEPA filters and low penetration air, or ULPA filters, to create a highly filtered clean air environment. The unit includes a circulating fan within the housing to draw air through the filters and housing and to exhaust the air through the top housing wall for recirculation, and can also be ducted to exhaust filtered air from the environment, either in whole or in part. A germicidal ultra violet light may be placed within the housing for additional air purification.
Claims20
A room air filtration unit comprising:
- a triangular housing having a triangular base, triangular top wall having an exhaust opening therein, and rectangular side walls wherein the housing defines a substantially open front face;
- a high efficiency particulate air filter mounted over the open front face of the housing to cover the front face;
- and
- a fan assembly mounted within the housing for drawing unpurified air into the housing through the filter and exhausting substantially purified air through the top wall opening, wherein the fan assembly has a rated pressure loading at least equal to the pressure drop rating of the high efficiency particulate air filter.
