Pneutorque® Pneumatic Multipliers
What is a Pneutorque® Pneumatic Wrench?
The Pneutorque consists of a robust air motor driving a Norbar
multiplier with three or more stages of epicyclic gearing.
Torque control is achieved by adjustment of the air pressure. An air
pressure versus torque graph and a calibration certificate is supplied with
each tool and allows specific torque values to be set. For more critical
applications, Pneutorques can be fitted with a torque transducer and the
precise torque output displayed.The tool can then be shut off at the
desired torque either manually or automatically using suitable control
circuitry.
Air pressure graph supplied with each tool.

The Lubro Control Unit, 16074, is Norbar’s filter / regulator /
lubricator. It is supplied with 3m of high quality steel braided air
hose and a 100mm pressure gauge for accurate setting.

The Twin Lubro, 16075, allows for a quick change of air pressure
or direction by virtue of a two direction switch on the side..

The Multi Channel Lubro, 60290, offers an ideal solution for
customers wishing to use a Pneutorque or other pneumatic tool
on multiple applications without having to refer constantly back
to air pressure graphs.

Why use Pneutorque® Pneumatic Wrenches?
Hand operated torque multipliers are ideal for low volume or intermittent use or when
there is no power source available. However, for production lines or whenever a large
number of bolts is involved, a powered multiplier will save a considerable amount of time.
Pneutorque operation is quiet – less than 85dB(A) with absolutely no impacting.These
two factors make Pneutorques comfortable for the operator to use, reducing fatigue
and consequently increasing safety.
Pneutorques provide accurate torque control – on a given joint they will stall repeatably
to within ±5%. Using electronic shut off, this repeatability can be improved to ±2%.

Summary of Pneutorque® Advantages
• Sound pressure level does not exceed 85dB(A) when tested in accordance with
ISO3744:1994.
• No impacting means less damage to the tool, socket and bolted assembly.
• Less operator fatigue, results in increased safety.
• Powerful – models available up to 300,000 N.m (220,000 lbf.ft).
• Repeatability of ±5% for accurate torque control.
• A wide range of attachments and accessories make Pneutorques adaptable to
many applications.
