How to choose the right low air pressure down hole Hammer?

In the drilling operation in mining, water conservancy engineering, foundation construction and other fields, low air pressure down hole hammer (usually working air pressure range is 0.7-1.4MPa) is popular because of its adaptability and low energy consumption. However, in the face of a wide variety of products on the market, how to choose the most suitable model? The following are the key purchase points:

1. Hole Diameter: Common low air pressure hammer is suitable for 90mm-200mm hole diameter, need to match the drill size.

2. Rock hardness: low air pressure models are suitable for medium hard rock formations (e.g. limestone, sandstone), if used for very hard rock (e.g. granite), high wear-resistant models should be selected.

3. Drilling depth: lightweight hammers are available for shallow holes (<20m); anti-fatigue design and stronger slag discharge capacity should be considered for deep holes (>30m).

4. Air pressure and air volume of air compressor: make sure the air pressure (e.g. 0.8-1.2MPa) and air volume (≥6m³/min) of air compressor meet the demand of impactor.
