Improved Engine ProtectionA certified upgrade is now available to replace the 30-year-old PUREair design. The new and improved unit provides a dramatic increase in dust separation efficiency and hence significantly increases the MTBUR for engine erosion.
The performance enhancements were achieved without any negative effect in terms of weight or power penalty compared to the previous equipment. In-service experience has demonstrated the superior performance of the PUREair system over other filtration devices that demand regular maintenance and cleaning.
