Low Pressure CIR90 DTH Hammers Drilling Hole for water well and
blasting
CIR90 DTH hammers are designed to operate effciently at low air
pressures and medium air pressures,using BR series bits. With professional manufacturing experience in DTH hammer
production, our factory can supply you with high pressure and
medium to low pressure DTH hammers. It strictly matches with API
standard and other Chinese industry standards.It is durable for
being produced with advanced craftwork and good material.
| Lengtgh(Without bit) | Weight(Without bit) | External diameter | Bit Shank | Hole Range | Working Pressure |
| 800mm | 20kg | ɸ80mm | CIR90 | ɸ90mm-ɸ100mm | 0.5-0.7 |
Main Features:
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.
