Applications

The DTH hammers are widely used in open-pit mining, underground mining, anchoring.quarrying, construction, etc.

Features of Low Air Pressure DTH Hammers

1 The operating air pressure are between 0.7Mpa and 1.75Mpa
2 Valveless hammers.
3 Simple structure, easy to assemble and to disassemble, long life span.
4 Higher impact frequency and faster drilling speed.
5 Lower air consumption and lower oil consumption. A hole can be drilled on the check valve to provide more efficient cuttings discharge.
6 Especially suitable for quarrying.
