Patent number: 8277735Abstract: This document describes a high intensity air purifier (HAIP), a super oxidation purifier, and a controller for controlling operation of any of various purification systems. In some implementations, a HAIP includes an air purifier system coupled within a housing having an air inlet and an air outlet. The air purifier system includes a pre-filter coupled to the air inlet, an axial fan for receiving and forwarding air from the air inlet. The air purifier system further includes a UV reaction chamber having a UV-light source for providing UV light to the forwarded air from the air inlet and a reflective lining to reflect the provided UV light, to provide UV purified air from the UV reaction chamber. The air purifier system further includes a chemical catalyst cartridge for receiving the UV purified air from the UV reaction chamber, for further purifying the UV purified air, and a post filter coupled to the air outlet.Type: GrantFiled: September 12, 2011Date of Patent: October 2, 2012Assignee: Blutec, LLCInventor: Rolf Engelhard
