Designed for demanding industrial bolting applications in hazardous-area environments, the Ingersoll Rand 3955B2TiEX ATEX Air Impact Wrench delivers 5,000 ft-lbs of maximum torque with a 1-1/2-inch square drive configuration and 2,750 RPM free speed. This super duty pneumatic impact wrench is engineered for heavy equipment maintenance, oil and gas service, and industrial applications where high torque output and ATEX-rated operation are required. Its Titanium hammer case helps reduce tool weight while maintaining the durability needed for severe working conditions.
The 3955B2TiEX features a TwinHammer impact mechanism (a dual-hammer system that delivers balanced impact energy for consistent torque output) and a pressure-feed lubrication system to support reliable operation during repetitive heavy-duty fastening tasks. The 1-1/2-inch drive provides compatibility with large impact sockets, while the ATEX configuration is designed for applications requiring equipment suitable for potentially explosive atmospheres. The supplied catalog confirms the ATEX model designation and core performance specifications; additional ATEX certification details should be verified from the manufacturer documentation if required.
