1. Special structure design reduces energy consumption, meantime, its drilling speed is faster than ordinary high air pressure DTH Hammer.
2. Adopt fine alloy steel and apply hardening treatment on the spare parts, which prolongs DTH Hammer lifetime and lifts reliability.
3. Valveless air distribution makes it more stable.
4. Simple and compact structure reduces wearing between spares and facilitates maintenance.
5. Multiple thread to connect sub and drive allows easy disassembly .
6. With the options with foot valve or without foot valve. With foot valve design, it helps prevent dust or water entering into the inside of hammer, especially for water well drilling or deep hole drilling. Without foot valve, it helps avoid the fault caused by its breakage and damage or due to temperature changes and which improves productivity.
