The T BIO-GAS filter is an advanced, modular, continuous-cycle air purification system for AHUs or with integrated autonomous ventilation that can be used in all air-conditioned buildings with the presence of pollutants (VOCs e.g. formaldehyde in buildings with wood and formica processing, ethylene in fruit and vegetable processing).
It uses an innovative method for air purification with particular attention to people's safety, avoiding the use of technologies that are harmful to health (ozone, UV, oxidative peroxides, etc.). An effective, safe and certified solution for the abatement of polluting gases.

This AHU filter has insertion characteristics such that it occupies the entire usable space in the HVAC section and at the same time possesses characteristics of lightness of construction and ease of installation.
Tonali E.A. also tested and certified that the filter's loading rate was low enough (<100Pa) not to impact the performance of the original aeraulic system.

For the realisation of this filter, special LEDs were chosen (to induce photocatalysis) that guarantee the lowest energy consumption. Innovative plastic materials were selected, which, in addition to the aforementioned characteristics of lightness and flexibility of installation, ensure high industrial circularity and maximum reduction of environmental impact with easy disposal.

By focusing on new technologies and innovative materials, Tonali E.A. has created a product that is easy to handle and position in the HVAC sector, which at the same time avoids the costly VMC and makes indoor environments healthy in a very short time, thus also avoiding labour disputes in the workplace.
