Vane air motor T850 series

boiler tubeATEXcompact

Overview
Designed for precise tube rolling and expansion, the T850 series pneumatic tube rolling drive features a lightweight aluminium body for easy handling. Adjustable torque control with an automatic stop prevents over-rolling when the preset torque is reached. Engineered for consistent, repeatable tube expansion in industrial heat exchangers, boilers and similar systems.

Product Features

• Adjustable speed and torque control for different tube materials and diameters
• Compact design for confined spaces such as heat exchangers and boiler drums
• Automatic stop mechanism to prevent over-expansion once the set torque is reached
• Low maintenance with minimal moving parts
• Explosion-proof execution available for hazardous areas
• Energy-efficient compressed-air operation

Typical Applications

• Tube expansion and rolling in heat exchangers
• Boiler tube expansion
• Industrial tube systems requiring uniform, controlled expansion
