FIELD: process engineering.
SUBSTANCE: invention relates to air cleaning systems using electric field for particles and materials polarisation and may be used in heating, ventilation and air conditioning systems, etc. Corrugated filtration material comprises multiple parallel conducting bulges to support the material and space folds surfaces apart. High voltage applied to between adjacent conducting bulges induced electrical static field in filtration material.
EFFECT: higher filtration efficiency.
