An improved powder delivery system for use in dispensing powder to a printing press. The improvements include an agitator system for the powder reservoir, a wiper block for use with a curved feed roller, a split air flow amplifier which is openable for cleaning, a flow-through rotary manifold for distributing powder to press and an improved powder spray block. The foregoing elements minimize the flow restrictions and enhance air and powder flow through the system. A control panel is provided at the operator\s console which is remote from the mounting position for the powder delivery apparatus. The control panel provides for, among other things, the delivery of powder at a fixed rate regardless of press speed or in accordance with variations in press speed. For example, in accordance with a factory determined linear relationship or an operator entered relationship. Such data can be stored for future reference and use.
