Spray Suppression System (3S) Rainflaps consists of unique surface formed by multiple tuffs / grass blades with a strong and sturdy backing. This surface contains the water spray and reduces the pulverization of water thus limiting formation of water spray. It absorbs the kinetic energy and guides the water downwards.

The containment of spray improves visibility considerably when the trucks move on wet roads thus making travel safer. The 3S performance meets the norms of ECE / EEC (European) standards in addition to AIS 013 (Indian) norms.
