FIF, FC and FIF-FC ionite vent filters are designed for air purification, ventilation emissions and gases from gaseous and aerosol admixtures in chemical, engineering, electronic, metallurgy, pulp-and-paper, glass, and plating industries, agriculture and other industries as well as for air purification from bad-smelling substances during communal wastewaters treatment.

Due to universality and simplicity ionite filters are easily built into inlet, exhaust ventilation systems and the systems for final purification of technological gases.
