Off-Highway Cooling Fans LS fans for compact equipment

compact equipment engine fan ls5

When it comes to a cooling package for smaller off-highway engines, every bit of space is precious. So Horton took its industry-leading fan blade technology and sized it appropriately.

Using computer-optimized blades for minimized deflection and reduced fan stress, these lightweight fans optimize airflow and efficiency in a wide range of on- and off-highway applications -- particularly those with a smaller engine envelope.
