Description
Ingersoll Rand 341A2M Backfill Tamper is a professional-grade pneumatic tool designed for the fast and effective compaction of soil, clay, and gravel in trenches, foundations, and other construction applications. Unlike lighter sand rammers, this tamper is built for the demanding task of consolidating backfill to prevent settling and ensure a solid, stable base for future construction.
The 341A2M is engineered to deliver a precise combination of force and speed, with a 1.63-inch bore and a long 4-inch stroke length that generates a powerful 1550 blows per minute (BPM). This high-frequency impact ensures rapid and uniform compaction, which is essential for meeting construction specifications and preventing costly rework.
Equipped with a standard 5-1/4-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.
