Baskar; Dr. C. Prajitha; Dr. S. Deepa; and Dr. K. P. Sridhar, Coimbatore, Tamil Nadu, on March 2, for 'metal engraver fume extraction and filtration device.'
Inventor(s) include Dr. S. Baskar; Dr. C. Prajitha; Dr. S. Deepa; and Dr. K. P. Sridhar.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to metal engraver fume extraction and filtration device designed to efficiently capture, filter, and purify hazardous fumes generated during metal engraving. The device has a funnel-shaped structure (100) configured to maximize the suction of fumes directly from the engraving zone. The funnel has an integrated honeycomb airflow stabilizer (101) that converts incoming centrifugal and turbulent air motion into a laminar flow, thereby improving filtration efficiency. The laminar air stream is directed toward a primary pre-filtration stage consisting of a mesh filter (102). The partially filtered air then moves to a secondary filtration unit comprising a reusable filter (103) in the form of roller is positioned in the form of a continuous spinning roller assembly. The reusable filter (103) absorbs fine pollutants, micro-particulates, and chemical residues from the incoming air stream. The reusable filter (103) is rotationally driven by DC motor (104). A controller unit (105) continuously monitors the pollutant saturation level and usage position of the reusable filter. If the filter is completely filled with dust particle, the controller sends a signal to actuate the DC motor (104), rotating the roller to expose a fresh, unused filter section to the airflow. If the roller reaches the end of the roll, the controller issues a maintenance alert indicating that the reusable filter needs to be removed, cleaned, and reinstalled. The fully filtered air is expelled through an air outlet port (106), ensuring safe discharge of clean air to the environments and the person working."
