Fan Balancing C-Clamps

 

Steel Balancing C-Clamps are used as permanent correction weights on vane axial flow fans and squirrel cage fans.  They have a serrated surface opposite the set screws that provides additional holding power.
 
We offer Double Sided Set Screw Steel Balancing C-Clamps
for harsh environments where additional stability is required.
 Stainless Steel Balancing C-Clamps are used in a few applications such as food and drug handling where non-reactivity is a priority.

 Protanium Balldriver L-Wrenches that withstand high torque and wear are recommended for use with SC-Clamps.

Double Sided Set Screw C-Clamps
These severe-duty balancing correction weight C-clamps are designed for harsher environments or high surface speed.  They have set screws on both jaws making them ideal for use in these situations or where fan blades may be corroded or other wise difficult to secure a weight to.  The set screws on one side of the C-clamp are tightened until the fan blade is locked in between the set screw points and the serrated surface on the other side of the clamp.  The second set of screws on the other jaw are then tightened to further secure the fan balancing weight.
