DOWIN T series breakers are very powerful and productive thanks to the cylinder embedded control valve system.
DOWIN T series breakers are designed to harmonize the long piston stroke with the nitrogen cushion on the top of the piston,creating less shock and vibration than competing breakers. Superior quality alloy steel provides excellent durability and longer life. Box Type breaker was developed to minimize the noise during operation, with use of soundabsorbing materials and noise reducing frame design, very useful in the job site of urban area. DOWIN T series provides a variety of selections with diversified 14 models.
