Ingersoll Rand 241A1M Floor Sand Rammer | 4" Stroke | 1590 BPM | 1.31" Bore

Built for compacting large floor molds and foundry casting beds, the Ingersoll Rand 241A1M Air Percussive Floor Sand Rammer delivers 1,590 blows per minute (BPM) with a 4-inch piston stroke and 1.5-inch bore to provide fast, consistent sand consolidation across larger molding areas. The higher blow rate and longer stroke generate the impact energy needed to achieve uniform mold density, helping improve casting quality while reducing manual effort during repetitive floor molding operations.

The 241A1M combines a proven pneumatic valve design (a reliable reciprocating air valve that provides consistent striking action), a plated piston, and a dual-action sand wiper that helps prevent abrasive particles from entering the cylinder. An integrated lubricator supports dependable internal lubrication, while the built-in muffler and side exhaust help create a cleaner, quieter working environment. These features make the tool well suited for foundries and casting facilities requiring reliable pneumatic performance throughout extended production shifts.

Tech Tip: To increase tool performance, extend tool life and lessen repair costs use it with a Filter-Regulator-Lubricator (FRLs)

Applications:

• Compacting molding sand in large floor molds used for iron, steel, and non-ferrous castings.
• Preparing foundry floor molds requiring consistent sand density across broad molding surfaces.
• Pattern shop operations involving large castings and heavy mold preparation.
• Industrial foundries performing production casting with repeatable mold compaction requirements.
• Repairing and reconditioning floor molds before casting operations.

FAQs:

• Q: What is the primary purpose of the 241A1M Floor Sand Rammer?
  A: It is designed to compact molding sand in large floor molds, producing dense, uniform molds that help improve casting consistency.
• Q: Why does this model use a 4-inch stroke?
  A: The longer piston stroke delivers greater impact energy, making it suitable for compacting larger volumes of molding sand than smaller bench rammers.
• Q: How does the dual-action sand wiper benefit the tool?
  A: It helps keep abrasive sand and debris from entering the cylinder, reducing internal wear and supporting dependable operation.
• Q: What compressed air connection does this rammer require?
  A: The tool features a 3/8-inch NPT air inlet, is intended for use with a 1/2-inch air hose, and consumes approximately 23 CFM during operation.
