Self-cleaning bag filters – DUSTdown^®

The DUSTdown® bag filter separates the solid particles in suspension from the air flow to be treated through the use of a physical filtering element. It is a self-cleaning filter, i.e. it is equipped with a system which is capable of removing the dust deposited on the filtering bags periodically. The use of this type of technology makes it possible to treat fine and ultrafine dust, thus achieving very high filtration efficiency levels.

Depending on the characteristics of the production process and on the dust that is present, the DUSTdown® bag filter can also be manufactured in the following versions:

• ATEX: DUSTdown® ATEX bag filters are used for flammable and explosive dust and for areas at risk of fire;
• High Temperature: DUSTdown® High Temperature filters are used in the presence of high temperature air flows.

• it is manufactured and configured according to the specific use in your business, taking into consideration quantity of dust and size of its particles, temperature and volumetric flow rate;
• it can be designed to achieve very high levels of efficiency: even more than 99.9% of dust can be removed;
• it allows the separated solid residue to be reused;
• it does not present any particular level of complexity and it is tested, reliable and cost-effective;
• it can be designed with proper dimensions for both limited and very high flow rates, as it is fully scalable and modular;
• it is suitable for ATEX certification, if dusts classified as explosive or flammable are to be handled;
• various possible discharge systems (manual, automatic or customised) can be provided in combination with the hopper;
• it is equipped with a ladder and railings which offer easy access to the filter roof for the replacement and maintenance of the filtering elements.

Over the years, we have developed bag filters for the filtration of fine and ultrafine dust in different contexts. They include:

• processing of special metals in Poland;
• grinding and recovery of disused household appliances;
• production of chemical agents;
• production of adhesives and detergents;
• herbicide production;
• paint production.

Tecnosida® also plans regular ordinary and extraordinary maintenance. This service is also available for DUSTdown® High Temperature and it ensures:

• proper functioning of the filter;
• high pollutant filtration efficiency;
• waste reduction (both in economic and energy terms)
