Ingersoll Rand 2940B2 Heavy Duty Air Impact Wrench | 1" Drive Size | 5000 RPM | 2000 (ft-lbs) Max Torque

Built for large fasteners that require substantial pneumatic impact power, the Ingersoll Rand 2940B2 combines a 1" square drive with a D-handle configuration for controlled two-handed operation in industrial maintenance, heavy equipment service, and demanding bolting applications. The tool operates at 5,000 RPM free speed and is part of the 2940 Series, which delivers 2,000 ft-lbs of maximum torque, providing the output required for large threaded connections where smaller impact wrenches may not provide sufficient capacity.

The 2940B2 uses a finely tuned twin hammer impact mechanism (two hammers delivering balanced blows to the anvil) designed to reduce vibration while supporting durability. Its 1,000–1,600 ft-lbs forward torque range, 850 blows per minute, inside-trigger actuation, and pressure-fed mechanism lubrication make it well suited to repetitive heavy bolting work. A cast iron hammer case and metal housing provide protection in demanding working conditions, while the bronze end plate adds corrosion resistance for exposed environments.

• 2,000 ft-lbs of maximum torque provides the output needed for demanding large-fastener applications.
• Cast iron hammer case and metal housing withstand harsh working conditions and repeated drops.
• D-handle configuration provides a stable two-handed grip for controlling the tool during heavy bolting operations.
• Inside trigger places tool actuation within the primary handle for convenient operation.
• Bronze end plate increases durability and provides corrosion resistance for outdoor and exposed working environments.
• Pressure-fed mechanism lubrication supplies lubricant to the impact mechanism during operation.
• Reverse bias motor supports fastener removal work, while the integral muffler helps manage exhaust noise.

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

Applications:

• Heavy equipment maintenance: loosening and installing large fasteners on construction, mining, agricultural, and material-handling machinery.
• Industrial MRO: servicing substantial bolted connections on plant machinery, presses, processing equipment, and mechanical assemblies.
• Fleet and commercial vehicle service: handling large fastening tasks on trucks, trailers, and heavy transportation equipment.
• Manufacturing operations: supporting repeated high-torque bolting tasks that require a 1" square drive and pneumatic power.
• Field equipment repair: removing stubborn large fasteners where adequate compressed-air capacity is available.

FAQs:

• Q: What size drive does the Ingersoll Rand 2940B2 use?
  A: The 2940B2 has a 1" square drive and should be used with compatible 1" drive impact-rated sockets selected for the fastener and application.
• Q: What is the torque range of the 2940B2?
  A: Ingersoll Rand lists a forward torque range of 1,000–1,600 ft-lbs (1,360–2,170 Nm) for the 2940B2. The 2940 Series is rated for 2,000 ft-lbs of maximum torque.
• Q: How much does the Ingersoll Rand 2940B2 weigh?
  A: The manufacturer lists the 2940B2 at 22 lbs (9.98 kg). Its D-handle configuration provides two-handed control when positioning and operating the tool.
• Q: What air supply does the 2940B2 require?
  A: The manufacturer specifies a 1/2" air inlet, a minimum 3/4" (19 mm) hose size, and 90 PSI operating pressure. The compressed-air system must provide adequate airflow through properly sized hose and fittings for the tool to perform as intended.
• Q: What is the difference between the 2940B2 and other 2940 Series models?
  A: The 2940B2 combines a D-handle, inside trigger, and 1" square drive. Other models in the series use different drive types, actuation arrangements, or handle configurations, so the model number should be matched carefully to the required setup.
