Abstract
The present invention relates to an air filtration system and a method for making a photocatalytic oxidation substrate by powder coating a photocatalyst onto a metal substrate.
Claims18
A method for applying a photocatalyst onto a substrate useful in a photocatalytic oxidation air filtration system comprising the steps of:
- a. mixing a metal oxide photocatalyst with a polymeric resin to form a photocatalyst-resin mixture;
- b. electrically charging the photocatalyst-resin mixture;
- spraying the photocatalyst mixture onto the substrate to form a metal oxide powder-coated substrate;
- and
- c. heating the photocatalyst powder-coated substrate.
2 more elements
An air filtration system comprising:
- a. a particulate filter;
- b. a motor fan for propelling airflow;
- c. a substrate powder coated with a photocatalyst;
- and
- d. a UV light source for irradiating UV light on the substrate.
2 more elements
An air filtration system comprising:
- a. a particulate filter;
- b. a substrate powder coated with a photocatalyst;
- c. at least one UV light source for irradiating UV light on the substrate;
- and
- d. at least one reflector positioned adjacent the at least one UV light source for reflecting UV light toward the substrate.
