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

Built for standing compaction work in foundries, casting facilities, and floor-level sand preparation, the Ingersoll Rand 241A1M Air Percussive Floor Sand Rammer delivers a 4" piston stroke and 1,590 blows per minute to help compact sand molds and prepared material with consistent percussive force. The floor configuration uses a long handle for upright operation, allowing the operator to work from a standing position while the rammer’s repeated impact action consolidates material below the butt.

With a 1.31" bore, 3" butt diameter, and 26.88 lb tool weight without accessory, the 241A1M is sized for more substantial compaction work than a bench sand rammer while remaining manageable for controlled floor operation. A front-end seal, plated piston, round piston rod, and dual-action sand wiper help protect the tool from dirt and grit in abrasive sand environments.

Type: Air Percussive Floor Sand Rammer | Model: 241A1M | Stroke: 4" / 102 mm | Bore: 1.31" / 33 mm | Blows Per Minute: 1,590 BPM | Air Consumption @ Load: 29 CFM / 821 L/min | Butt Diameter: 3" / 76 mm | Weight w/o Accessory: 26.88 lb / 12.2 kg | Length w/o Accessory: 52.75" / 1370 mm | Air Inlet NPT: 1/4"

Features:

• Floor-style rammer configuration supports standing operation for sand compaction tasks at floor level.
• 4" piston stroke provides repeated impact travel for compacting prepared sand and similar foundry materials.
• 1,590 blows per minute delivers fast percussive action for efficient material consolidation.
• Front-end seal helps protect internal components from abrasive sand, dirt, and grit during operation.
• Plated piston supports durability in harsh compaction environments where contamination can shorten tool life.
• Round piston rod and dual-action sand wiper help keep debris out of the barrel.
• 3" butt diameter is standard on the 241A1M for floor sand rammer applications.

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

Applications:

• Foundry sand mold preparation where controlled compaction is needed around larger floor molds.
• Casting facilities compacting prepared sand before pouring operations.
• Maintenance and pattern shop environments where pneumatic sand ramming is preferred over manual tamping.
• Floor-level compaction tasks that require upright tool handling instead of bench-style operation.
• Industrial shops working with abrasive sand materials where sealing and debris protection matter.

FAQs:

• Q: What is a floor sand rammer used for?
  A: A floor sand rammer is used to compact sand molds and prepared sand materials at floor level, especially in foundry and casting work. The long-handle configuration allows standing operation while the tool delivers repeated percussive blows into the material.
• Q: How is the 241A1M different from a bench sand rammer?
  A: The 241A1M is a floor sand rammer with a longer 52.75" length and standing-use configuration. Bench sand rammers are shorter tools intended for smaller mold work at a bench or table.
• Q: What air supply does the 241A1M require?
  A: Manufacturer data lists 29 CFM air consumption at load, a 1/4" NPT air inlet, and a 3/8" minimum hose size. As with most pneumatic construction tools, the air system should be sized to maintain proper pressure during continuous use.
• Q: What does “blows per minute” mean on this tool?
  A: Blows per minute, or BPM, is the number of percussive impacts the tool delivers in one minute. The 241A1M is rated at 1,590 BPM, giving it rapid repeated impact action for compacting sand.
• Q: Does this rammer include alternate butts?
  A: The listed manufacturer data identifies a 3" butt diameter for the 241A1M. Accessory butts may be available separately, but included accessories should be verified before ordering.
