Impact Wrench Pansam A533161 1/2" Drive, 7 bar Air Pressure

Pansam A533161 is a pneumatic impact wrench with a 1/2" drive designed to deliver repeated high-torque impacts for fastening and loosening nuts and bolts. Specified for operation at 7 bar air pressure, the tool uses an internal hammer mechanism to convert compressed air into powerful rotational force while enabling fast socket changes and continuous operation in workshop and service environments.

Advantages

The impact wrench provides consistent pneumatic torque output at the specified 7 bar working pressure, enabling efficient removal and installation of threaded fasteners. Its 1/2" square drive supports a wide range of sockets for automotive and industrial tasks. The hammer mechanism ensures repeated impactful blows for improved loosen-up performance compared with manual or slower power tools, and the pneumatic design provides high power-to-weight ratio for prolonged use.

Suitable for

• Automotive wheel and suspension maintenance
• General workshop fastening and disassembly tasks
• Assembly and production line operations requiring rapid torque application
• Maintenance tasks where pneumatic tools and compressed air are available

Key specifications

• Drive size: 1/2" square drive for standard sockets
• Operating medium: compressed air
• Recommended working pressure: 7 bar
• Impact mechanism: internal hammer-style impact unit
• Primary use: fastening and loosening of nuts and bolts in workshop and service settings

How to use

Connect the impact wrench to a clean, lubricated compressed air supply set to the recommended 7 bar working pressure and use an appropriate air hose and fittings rated for that pressure. Fit a compatible 1/2" socket to the square drive and select the correct socket size for the fastener. Hold the tool firmly, position the socket on the fastener, and apply short bursts of trigger input to control torque application while loosening or tightening. After use, disconnect air supply, wipe the tool clean, and follow the manufacturer's maintenance guidance such as periodic lubrication of the air inlet and inspection of the impact mechanism.

Usage recommendations

Use personal protective equipment such as eye and hearing protection when operating the impact wrench. Ensure the air supply is regulated to the recommended 7 bar and include an inline filter and lubricator to prolong tool life. For controlled tightening, consider using a calibrated torque wrench to verify final torque values after initial pneumatic fastening.
