Ingersoll Rand 3940B2Ti 1-In. 2,500 ft-lb Air Impact Wrench
Product Overview
The Ingersoll Rand 3940B2Ti 1-In. Air Impact Wrench is a heavy-duty pneumatic impact tool designed for demanding maintenance, automotive, fleet, construction, and industrial applications. With a 1-inch square drive and up to 2,500 ft-lb of maximum torque, it is built to handle large fasteners that require significantly more power than standard impact wrenches.
Its pneumatic design makes it well suited to professional service environments where high torque, durability, and dependable operation are important.
Key Features
- 1-inch square drive for large impact sockets.
- Up to 2,500 ft-lb maximum torque.
- Pneumatic operation for professional heavy-duty use.
- Designed for demanding fastening and removal applications.
- Suitable for automotive, fleet, construction, and industrial maintenance.
- Heavy-duty construction for professional environments.
- Compatible with appropriately rated impact sockets and accessories.
- Designed for applications involving large, difficult-to-remove fasteners.
High-Torque Performance
The 3940B2Ti is designed to deliver substantial torque for demanding fastening and removal work.
Its 2,500 ft-lb maximum torque rating provides the force required for applications involving large fasteners commonly found on:
- Heavy trucks
- Buses
- Construction equipment
- Agricultural machinery
- Industrial machinery
- Trailers
- Large mechanical assemblies
The maximum torque rating should not be treated as a universal tightening specification. For critical fasteners, always follow the equipment manufacturer's specified torque and use a calibrated torque wrench or approved torque-control system for final tightening.
1-Inch Square Drive
The 1-inch square drive accommodates large impact sockets intended for heavy-duty fastening applications.
Compared with smaller 1/2-inch and 3/4-inch impact wrenches, the 1-inch drive format is designed for larger fasteners and higher-load applications.
For safe operation, use only impact-rated sockets and accessories that are correctly sized for the tool and fastener.
Pneumatic Design
The 3940B2Ti operates using compressed air, eliminating the need for batteries or an integrated electric motor.
Performance depends on the quality and capacity of the compressed-air system. Maintaining adequate air pressure and airflow at the tool is essential for achieving consistent torque.
Factors that can affect output include:
- Air pressure
- Available CFM
- Hose diameter and length
- Coupler and fitting restrictions
- Air-line leaks
- Fastener condition
- Tool maintenance
For professional use, the compressor and air-distribution system should be sized to meet the tool's requirements during actual operation.
Recommended Applications
Heavy-Duty Automotive Service
The wrench is suitable for large vehicle fasteners encountered during truck, trailer, bus, and commercial vehicle maintenance.
Fleet Maintenance
Useful for service departments working on commercial fleets where technicians regularly encounter large and stubborn fasteners.
Construction Equipment
Appropriate for maintenance of heavy equipment such as loaders, excavators, cranes, and other machinery.
Agricultural Equipment
The high torque capacity can be useful for servicing tractors, combines, implements, and other agricultural machinery.
Industrial Maintenance
Suitable for heavy mechanical assemblies and industrial equipment where large fasteners require substantial torque.

Air Supply
A high-torque pneumatic impact wrench requires an appropriately sized compressed-air system.
For reliable performance:
- Use a compressor capable of supplying the required airflow.
- Maintain the recommended operating pressure.
- Use an appropriately sized air hose.
- Avoid restrictive fittings and undersized couplers.
- Inspect the air system for leaks.
- Use clean, dry compressed air.
- Maintain the tool according to the manufacturer's recommendations.
Important: Compressor tank capacity alone does not determine tool performance. The compressor's delivered airflow and the amount of pressure maintained at the tool are more relevant.
Fastening and Removal
The 3940B2Ti is particularly useful when removing heavily tightened, corroded, or seized fasteners.
For final tightening of safety-critical fasteners:
- Use the impact wrench to run the fastener into position.
- Avoid relying on the impactool's maximum torque as the final tightening value.
- Finish tightening with a calibrated torque wrench when specified.
- Follow the equipment manufacturer's torque requirements.
This procedure helps prevent over-tightening and potential damage to fasteners or components.
Maintenance
Regular care helps maintain reliable performance and extend tool life.
Recommended practices include:
- Lubricate the impact wrench as specified by Ingersoll Rand.
- Use clean and properly conditioned compressed air.
- Inspect the air inlet and connections.
- Check the square drive for excessive wear.
- Inspect sockets before use.
- Keep the tool clean.
- Check for unusual vibration, noise, or air leakage.
- Have worn internal components serviced by qualified personnel.
Safety Features and Best Practices
Because this tool can produce extremely high torque, proper handling is essential.
Always:
- Wear appropriate eye and hearing protection.
- Use properly rated impact sockets.
- Never use damaged or worn sockets.
- Keep hands clear of the rotating drive.
- Secure the workpiece before operating the tool.
- Disconnect the air supply before maintenance.
- Do not exceed the manufacturer's recommended air pressure.
- Follow the tool manufacturer's operating instructions.
High-torque pneumatic tools can cause serious injury or equipment damage if used incorrectly.
Why Choose the Ingersoll Rand 3940B2Ti?
The Ingersoll Rand 3940B2Ti 1-In. Air Impact Wrench is designed for professionals who need considerably more torque than a conventional shop impact wrench can provide.
Its combination of a 1-inch square drive and 2,500 ft-lb maximum torque makes it a strong choice for heavy trucks, construction machinery, agricultural equipment, industrial machinery, and other applications involving large fasteners.
Its pneumatic design also makes it well suited to professional workshops and maintenance facilities that already have a suitable compressed-air system.
What's Included
- 1 × Ingersoll Rand 3940B2Ti 1-In. Air Impact Wrench
Impact sockets, air hose, couplers, compressor, lubricants, and other accessories are not included unless specifically stated by the seller.
Important Torque Note
The 2,500 ft-lb figure represents the tool's maximum torque rating and should not be interpreted as the recommended tightening torque for every application. Actual torque can vary according to air pressure, airflow, hose and fitting configuration, fastener condition, and operating technique. Always use the equipment manufacturer's specified torque values for critical fasteners.
