The Defence Research Development Organization has developed the SUMERU PACS, that helps to reduce sweating of Personal Protective Equipment wearers.


The DRDO scientists found that the PPE wearers felt very uncomfortable after wearing them for more than 30 minutes. They start sweating and this worsens the situation.

In order, to solve this problem, personal air circulation system was developed by DRDO. The system is to be used inside the PPE as a small backpack of 500 grams. This has been named SUMERU PACS. They keep the wearer away from sweats.

About the system

The system draws outside air and the moist air goes out through a front face opening. This cools the neck and head area. The system is highly helpful for doctors and medical staffs who are forced to wear PPEs more than six hours in hospitals.
