What is Dust?

Dust formed during a variety of applications where dry materials are processed. For example durign welding, laser and plasma cutting, dry grinding, sanding or varnishing. Dust consists of airborne particles up to 100 microns, which is equivalent to one tenth of a millimeter. Larger particles that not airborne are also considered to be dust particles.

How is it handled?

When we design a dust filter system, there are many things that we have to take into consideration. What airflow needed? What dust content do we have? Is it explosive? etc. The process will be the most energy-efficient and effective if it is encapsulated. We at Absolent are happy to help with this.

Absolent has the solution!

An Absolent filter unit for dust filtration contains several filter cartridges and is based on the latest and most efficient filter technology. The Absolent filter units with automatic compressed-air cleaning function is especially well suited for continuous operation.

How does it work?

The particles will follow the air stream into the filter unit. The heaviest dust particles fall directly into the dust container. Other particles follow the air and stick to the outside of the cartridges we’ve placed hanging in our dust filter units. The dust formas a thick cake on the cartridge whcih also works as a filter. It is important that the particles do not penetrate into the filter material. When the cake of dust has become thick enough our automatic pressure monitor  send out a pneumatic shock from the inside out through the cartridge. The dust falls down toward the dust-tub. This is what we call down-flow. Then filtered air can be led back into the room or outdoors. The airflows assoisated with dust filtration are often relatively large. Therefore it is common to pass the air through a heat exchanger before it is led out in order to reduce energy consumption. The cartridges can usually be washed before they need to be replaced.
