Activated carbon bag filter City Flo
I. Product Introduction
The "City Flo" Activated Carbon Bag Filter is a high-capacity, energy-efficient gas-phase filtration solution designed for urban air purification systems. Featuring a deep-pleated bag design with impregnated activated carbon, it effectively removes VOCs, odors, and toxic gases from commercial and industrial ventilation systems.
II. Product Advantages
Can be used to upgrade existing installations
Robust metal header frame
Removal of solid and gaseous contaminants in one filter stage
Ideal for filtering moderate concentrations of most external and internal source pollutants
The broad spectrum carbon operates with a Rapid Adsorption Dynamics (RAD) mechanism that is specifically designed to be highly efficient against the multiple chemicals that are typically present in low or moderate concentrations in city-centre buildings or other locations.
The City-Flo filter provides particle filtration in classes F7 or F9 according to EN 779:2012. A high media area ensures high efficiency, long life and low pressure drop.
