The present invention is related to preventing dust agglomeration on a sharp electrode which is used for generating corona. According to certain aspects, the invention includes a dust shroud which decreases or prevents dust accumulation on the sharp electrodes. The dust shroud changes the gas flow path so as to reduce the amount of gas passing near the sharp electrode. An advantage of the shroud is that it prevents dust from building up on the electrodes. The shroud is a simple, passive addition to the electrostatic pump, such that the pump is otherwise able to operate normally throughout its life. In embodiments, the shroud can be used to protect a corona electrode used in heat sink applications especially in electronics cooling. It can also be used in electrostatic precipitators for cleaning dust or chemical or microbe particles from air.
