Description de produit
Low Air Pressure CIR90 DTH Hammer | Central Exhaust Design

The CIR90 Low Air Pressure DTH Hammer is a highly reliable valved down-the-hole hammer featuring an impact mechanism with plate valve, single piston, and central exhaust structure. Engineered specifically for low-air-pressure operating conditions, its robust design ensures stable impact performance at air pressures ranging from 0.5 to 0.7 MPa.

Performance Characteristics
  • High single-impact energy with low energy consumption during rock drilling
  • Optimal weight ratio between piston and drill bit with prolonged effective action duration for improved drilling efficiency and extended tool service life
  • Excellent central exhaust and cuttings discharge capabilities to minimize re-crushing of rock fragments
  • Equipped with check valve assembly for underwater rock drilling operations

Applications
Widely used in mining, quarrying, water well drilling, and engineering blasting applications.
