DRDO develops CO filters for submarines

Like any automobile, submarines generate a lot of harmful gases like carbon-mono-oxide (CO). India was importing special room filters for submarines which could absorb CO as well as other gases.

To ensure safety of the Naval staff, the Defence Research Development Organization (DRDO) has not only developed its own CO filters called 'CFKIII room filters' but also room filters that can absorb over 40 different gases, at almost one fifth of the imported cost.

The information on CO filter is on display at the three-day AXIS technical festival organized by students of the Visvesvaraya National Institute of Technology (VNIT). In fact, India is the first country to develop a CO filter which can work for indefinite period even in heavy moisture conditions as compared to the Russian filter costing about Rs1 lakh.
