Rockmore International’s new A-Series DTH hammer line, designed for more efficient use of compressed air, makes the hammers compatible with a wider range of compressors.
Smaller compressors rated less than 1,000 SCFM may be utilized to reach the hammer’s peak performance. Larger air compressors may be regulated back to lower settings without experienceing loss in penetration rates.
