Abstract
A Precipitator Rapper is disclosed having a non-magnetic tube adjustably attached to a solenoid and a hammer extending through the solenoid and through the tube. The solenoid is adjustable toward and away from the precipitator and the tube has a removal cap on the end remote from the precipitator that can be removed so that an accurate measurement can be made from the hammer to the outer end of the tube. This enables a person to accurately adjust the hammer relative to the tube.
