Electrostatic Precipitator Efficiency Calculator

An electrostatic precipitator (ESP) is a filterless device that removes fine particles, such as dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.

Deutsch-Anderson equation:
η = 1 e ( W A / Q )


η = fractional collection efficiency
W = terminal drift velocity
A = total collection area
Q = volumetric gas flowrate

Note that any consistent set of units can be used for W, A, and Q (e.g., ft/min, ft2 , and ft3 /min).
