Shock Absorber – DTH
Pneumec Down-the-hole (DTH) Shock Absorber is a strong and flexible equipment designed to provide maximum protection of your complete drill string. It connects right above the DTH Hammer, and no matter what the depth of the hole, it always provides the maximum absorption of the shock waves created by the DTH hammer, resulting in less adverse effect to the drill rods and rotators above it. Top and bottom connections of the DTH Shock Absorbers are standard API, or they can be tailor made to your specification.
