Tunnel production is a complex and challenging process that requires various tools and machinery for drilling, blasting, ventilation, and material handling. Many of these works depend on pneumatic tools that need constant compressed air. In tunnel production, one of the vital pieces of equipment is a screw type compressor that delivers constant compressed air in drilling, blasting, ventilation, and many more. Let’s take a look in depth at how a rotary screw type air compressor plays an essential role.
