How do our ODM type dust collectors work?


The good quality of air at working place is of vital importance not only for the health and safety reasons concerning the employees, but also in terms of good maintenance of the processing machines and production lines. One of the most multifuncitonal and effective solution for dust collecting are our ODM type dust collectors. How do they work?

The structure of the ODM dust collectors

Our ODM dust collectors are of modular structure made of continuously galvanized and cold formed carbon steel sheets. The adequate selection of high quality materials is a guarantee of a top performance of our dust collectors and their resistance to various conditions. Additionally, the structure of the ODM dust collectors is additionally sealed with silicon at the so called key points. The standardized filter modules can be combined together and this way it is possible to extend the filter by next modules adapting the device to the individual needs of the given production plant.

How does it work?

The rule is pretty simple, the device is designed to separate the dust (such as sawdust, chips or cement particles etc) from the air – once the dirty air goes through the filtrating process and is cleaned, it is returned to the working area. The whole process begins with the dirty air being delivered to the dust collector into the filtration chamber, where the filtration takes place. In our ODM dust collectors we use filter cartridges – pleaded (patrons) or cassette types – selected individually for each dust collector in terms of their dimension, filtrating surface, efficiency, etc. The filter cartridges are produced of woven fabrics which stop the particles of dirt. The dust and all other particles of dirt fall down into the discharge hopper from where they are disposed of. Meanwhile, the filtrated, now clean air is directed into the outlet ducts and returned into the production hall.

Filter cleaning

Each filter (dust collector) has limited capacity, which means they need to be regularly cleaned – otherwise they do not work properly or efficiently. In the ODM dust collectors we use automatic cleaning system with the use of compressed air. The cleaning is controlled by a programmed controller which measures the pressure difference inside the filtration chamber and initiates the cleaning process when the pressure drop is bigger than the set value. The frequency of cleaning depends on the dust type and the ODM load. The separated dust and dirt can be removed from underneath the dust collector directly into bins or with the use of a rotary valve, or a screw conveyor connected to a rotary valve – it all depends on individual needs.

Explosion decompression panels

An important component of the ODM dust collectors are the explosion decompression panels (also called explosion vents) compliant with the ATEX directive. Their task is to relieve (decouple) the explosion. In case of fire and explosion of combustible dust inside a dust collector, decompression panels open immediately and the pressure and flame of the explosion is vented outside the dust collector together with the burnt and not burnt waste. It is crucial to make sure the area into which the explosion is to be directed into is clearly marked and that no person enters it.

Application of the ODM dust collectors

These dust collectors are widely used in various industries, among them are:

  • cement industry
  • metal processing
  • wood processing
  • chemical plants
  • plastic processing

Summarizing, our ODM dust collectors are not only efficient and multifunctional devices, but they also provide failure free, highly efficient and simple operation. You are welcome to contact us – our specialists will advise you on the tailored made selection of dedusting system for your needs.
