The paper and pulp production processes generate large amounts of dust and other residues, such as edge trimming, which are drawn directly into the process points and conveyed into large sleeve filters. Due to the risk of explosion, sleeve filters are usually installed outside the production facility and require considerable space and resources for replacement. In addition, there are problems with condensation during the cold season.

The air treatment developed for this application is very close to a grey room concept, or an area within environmental and cleaning parameters must be guaranteed, in accordance with the product’s requirements and the accompanying certifications.
Therefore, Canalair designs and sizes the plant using a high efficiency ventilation system complete with heating, cooling and humidification.

This machine is then completed with a network of diffusers at low speeds to supply air conditioning inside the working area and, simultaneously, recover the ambient air through grids and shooting points in strategic areas of the line.
This application is important to ensure an adequate recirculation and, consequently, a high level of cleaning from dust, microdusts and other airborne contaminants.
