CSIR-Central Mechanical Engineering Research Institute, Durgapur unveiled the CSIR-CMERI developed Outdoor Air Purifier at its residential campus in Durgapur (West Bengal). Prof.(Dr.) Harish Hirani, Director, CSIR-CMERI said that Air Pollution due to industries and automobile is the major cause of concern these days. Particularly during the pandemic COVID period, it was especially noticeable on account of more getting an environment free from pollution as well as microorganisms, bacteria, and viruses, etc.

Prof. Hirani briefly explaining about the technology of the product, said that Indoor Air Cleaner and purifiers are available in the market but it is an outdoor one which has a radial range of 5 meters. With its help air pollution can be reduced by 50% depending on the environment and pollution level. A customized adjustable timer can be set for the most pollution period say 8 AM to 6 PM.

The machine is very cost-effective and has a low maintenance cost. We can clean it with a vacuum cleaner. These air purifiers have been installed on the street light poles focusing the narrow lanes of the campus and the machine also runs on solar power. Considering the comprehensive features, used components, and materials, the existing cost of a unit comes to 25 thousand rupees which may go up to 30 thousand rupees inclusive of taxes. This cost can be well reduced when the steel sheet body is replaced by plastic and the UV lamp is removed or customized as per requirement.

Pradip Kumar Das, Joint Director, Br. MSME-DI, Durgapur, Govt. of India on this occasion appreciated the role of CSIR-CMERI and its continuous R&D innovations towards self-sustenance, import-substitution, and for the Atmanirbhar Bharat. He described the product as a very innovative one and requested the MSMEs to come forward for mutual benefits with the technological developments and innovation of the Institute. Shri Das pleaded that in this virtual global environment the availability of MSMEs on Government e-Marketplace (GeM) is very low which needs to be improved for providing skill and employment opportunities to the youths of this region also.
