Filter Systems


A good industrial filter system is an indispensable component of every manufacturing plant. With an industrial air purifier system you can reliably remove chips, dust and abrasion from the air in your plant. As processing residues, these fine particles always represent a high risk for the health of your employees, for the service life of your machines and for the quality of your products in every craft and industrial enterprise. In addition to health and fire hazards, unnecessarily long tool life and quality complaints for NESTRO® filter systems speak for various types of dust. Wood, paper and corrugated board, metal, plastic and leather are just a few examples. We offer industry air filter systems for all these areas. By using innovative technologies, our filter systems help to reduce energy consumption and promote sustainable production processes. They help to minimise the consumption of resources and reduce environmental pollution. We offer customised filter systems that are precisely tailored to your individual needs. Our experienced team is on hand to support you in selecting and implementing the optimum filter system.

How do filter systems work?

In simple terms, filter systems extract so-called raw gas (air with dust, chips, punching residues, etc.) from the processing machine, filter out the substances for further processing and return so-called clean gas (air with a residual dust content of less than 0.1 mg/m³) back into the workshop. This makes the air cleaner than the outside air!

What are the components of a filter system?

A filter system always consists of machine connections, piping, fan, filter unit with cleaning, discharge and return air duct.

What do you have to look out for in filters?

 The overall solution must fit your operation and your specific application. It is usually not about a single product, but a complete system. In any case, let us advise you.

Do filter systems need to be cleaned?

Like all machines, filter systems must be monitored regularly in accordance with the operating instructions. However, cleaning of the filter bags or cartridges is done automatically via motorised vibration or by means of compressed air pulse cleaning (JET). The discharge empties the filter and feeds the material to its further use.
