How does a pneumatic impact wrench work?
Designed for clamping, any precision task will need to be completed with a torque wrench - to ensure a good tightening.
To avoid buying one pneumatic driver for each different diameter, the sockets are interchangeable . Genius!
What are the characteristics of a pneumatic impact wrench?
To avoid damaging these infamous fastener's heads, consult the torque chart to get a better understanding of the torque needed - in comparison to the diameter.
Avoid under-charging the wrench, otherwise you will be finishing the operation by hand.
The impacts per minute determines the tightening speed. The higher the number, the more ttoque is applied to the offending screw or bolt.
The tool's weight is important for better maneuverability;
The anvil's coating;
The ergonomics of the handle;
The spiking speed relative to the impacts per minute;
The sound level, expressed in decibels (dB);
- A Power regulator to accommodate different bolts;
- A variable speed trigger;
The spiking torque - for maximum loosening force;
- An exhaust vent to prevent backlash from the user.
Pneumatic impact wrench and compressors: air flow and pressure
Since the driver operates with an air supply from a compressor, it is crucial to match the energy provided with the requirements of the tool.
To accomplish this, pay close attention to:
- The operating pressure expressed in bars (B) needed by the wrench;
- The required air flow rate expressed in liters per minute (l / min).
Advice on choosing a pneumatic impact wrench
The reservoir's volume will determine the tool's time of use, since it has no engine in need of re-pressurizing the air.
A minimum of 50 liters (l) is required for the smaller of the pneumatic impact wrenches.
Always plan according to the intended task and the recommended boltage settings to be sure to get the right torque, otherwise your pneumatic impact wrench can be over or under-charged and can result in damage or frustration.
