The process is founded on the deposition of particles (fogs, dust, bacteria,...) contained in the air and gases, by a system of ionization and electrofiltration. The flow of air charged with particles crosses a cylindrical tube. An electrode ionizes the particles which then are collected and trapped by a metal knitting in periphery.
This principle makes it possible to purify, cleanse, recycle and deodorize the ambient air of public spaces, or industrialists (Industries of treatments of waste, of refining, the iron and steel industry, the nuclear plants, the tunnels, the undergrounds, the offices, the hotels, the restaurants, the hospitals, agribusiness industries, the diesel engines....).

According to the Ecomesure study realized in 2007, ACOFILTRE-Atec makes it possible to destroy 99.9% of the toxic particles contained in the ambient air and in particular in confined spaces. This electrostatic precipitator can collect particles lower than 0. 03 Microns. (study at disposal)

Contrary to the other systems, ACOFILTRE-Atec is not stopped and requires a cleaning only every 2 years, without change of parts nor necessary particular technical skills. It functions with low as at high temperature, until 900°c. (For example, the power stations of treatment of air competitors function only until 100°c!). In addition ACOFILTRE-Atec makes it possible to treat great flows without pressure loss thus generating serious energy saving. This system is incorporated very easily in ventilation ducts.
