SK28SR-6 MINI EXCAVATOR
Redesigned SR Series Mini to Reduce Fuel Consumption and Noise Now KOBELCO has taken the next evolutionary step by packing even more digging power and practical performance features into the SR series mini excavators while maintaining a short tail swing. The new Energy Conservation Mode saves even more fuel, and KOBELCO’s proprietary iNDr Cooling System ensures quiet operation, protection from dust, and easy maintenance. It all adds up to enhanced full size performance, short-radius agility and a low-noise environment, with exceptional performance features and full range of value-added functions.
The highly airtight engine compartment and the offset duct contribute to noise reduction. The iNDr filter fitted in front of the cooling system ensures easy cleaning. The iNDr system on the SR series mini excavators features air intake at the front of the machine and air exhaust underneath. It functions in the same way as the iNDr System on the SR series machines.
iNDr Filter The high-performance iNDr filter removes dust from intake air.
