KT7C high pressure down the hole drill rig for open use is
an advanced drilling device integrating down the hole drilling
system and screw air compression system, typical of compact
structure, excellent integrity and mobility.
Permanent magnet variable frequency screw air compressor can maintain high motor efficiency at any speed, so the energy-saving effect is much better than that of ordinary screw air compressor.
The cooling system design is especially suitable for high temperature and high humidity environment in Asia. It has excellent vibration isolation technology and noise reduction measures.
