    Valveless air distribution hammer, more reliable of air distribution.

     

    Good sealabIlity, no water, and cuttings entering into hammer in water exist drilling.

     

    High Air Pressure DTH Hammers Without Foot Valve Advantages:

     

    1. Out of the trouble of foot valve fracture and expansion and contraction.

    2. Lower energy consumption and higher impact frequency.

    The drilling speed is 15-30% higher than the one with foot valve.

    3. Simple structure, reliable parts, long life span, easy and cheap maintenance.

    4. Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.

     

     

    QL Series DTH Hammers Features:

     

    1. Valveless air distribution, more reliable.

    2. The simple design of the piston. Long life span.
