Description
Ingersoll Rand 441A2 Backfill Tamper is a professional-grade pneumatic tool designed for the fast and effective compaction of soil, clay, and gravel in the most demanding construction applications. With a larger bore, higher BPM, and heavier construction than other models, this tamper is built for heavy-duty work, ensuring a solid and stable base for all types of construction.
The 441A2 is engineered to deliver a precise combination of force and speed, with a 2-inch bore and a long 4-inch stroke length that generates a powerful 1750 blows per minute (BPM). This high-frequency and high-impact combination ensures rapid and uniform compaction, which is essential for meeting rigorous construction specifications and preventing costly settling and rework.
Equipped with a standard 6-inch diameter butt, this tamper is ideal for covering a large surface area quickly and effectively. Its durable construction and optimized air consumption make it a reliable workhorse for continuous, heavy-duty use in demanding industrial environments. The tool's extended length allows the operator to work comfortably from a standing position, minimizing fatigue while maximizing productivity.
