MUMBAI, India, July 7 -- Intellectual Property India has published a patent application (202621055982 A) filed by Rizwan Ahmad on May 02, 2026, for A System And A Method Of Chimney-Style Chemical Fume Purification.
Inventor includes Rizwan Ahmad.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: Disclosed is an invention relating to a system (10) for chemical fume extraction and cooling-neutral air purification configured to perform localized source-level capture, multi-stage filtration, and closed-loop recirculation of air within an indoor environment. The system (10) comprises an adjustable suction hood (24) positioned proximal to a chemical fumes emission zone (14), a flexible suction duct (16), and an air intake section (18) for conveying contaminated air into a purification chamber (34). A multi-stage filtration assembly including a pre-filter unit (26), a HEPA filter unit (28), an activated carbon filter unit (30), and a formaldehyde catalyst filter (32) enables progressive removal of particulates and chemical vapors. An energy-efficient motor (44) generates controlled airflow, while an air quality sensor (40) and a control unit (42) dynamically regulate operation based on real-time conditions.
