Propeller balance is sensitive and can be negatively affected by slight pressure. Simply resting the motor and propeller assembly on the ground after disassembly from a condensing unit can make a propeller unbalanced. This is especially true of original equipment propellers because they are constructed of lighter gauge material. Using an unbalanced or damaged propeller can ruin a motor.
Lau Heavy Duty Replacement Propellers are designed to hold their balance in the toughest applications. It is less expensive to install a new Lau Heavy Duty Replacement Propeller than to replace a damaged motor.
