Reliable shut-off control, ergonomic handling, and repeatable assembly performance.
The Atlas Copco LUM PR family is built for controlled fastening in industrial assembly lines where repeatable torque accuracy matters.
With straight-body handling, push start operation, and button reverse, it fits assembly stations that demand productivity, durability, and consistent tightening results.
How do I choose the right LUM PR model?
Step 1: Define the torque range required for the joint.
Step 2: Match the speed to the assembly cycle and fastening behavior.
Step 3: Check the tool length and weight against the workstation layout.
Step 4: Confirm the air connection and hose setup for your line.
When should I choose a higher-speed model?
Choose a faster model when the application calls for higher cycle speed and the joint can be fastened quickly while staying within the required torque range.
Are all models suitable for the same workstation?
Not always.
The right choice depends on torque demand, speed, tool length, weight, and how the operator reaches the fastening point.
What is the benefit of push start and button reverse?
It simplifies repetitive assembly work.
The operator can start fastening quickly and reverse the tool with a simple button action.
What maintenance does a pneumatic screwdriver like this need?
Keep the air supply stable, inspect hoses and connections regularly, and follow routine plant maintenance practices to preserve consistent performance.
What is included when ordering a LUM PR model?
Orders are placed by model and ordering number.
It is best to confirm the exact supplied configuration and any included accessories for the selected model.
