High-pressure dust extraction system

Suction systems with high pressure and high head filters are necessary in a company when the residual material to be extracted is large, such as coarse dust or chips. In these cases it is necessary to achieve a strong concentrated suction, which is capable of extracting even heavy materials. High-pressure extraction systems can also be designed for cleaning surfaces or workstations.

These plants are characterised by small-diameter pipes and high-speed air flows, capable of transporting chips and heavy dust. To learn more about this topic, read the article here where we discuss the differences between extraction systems for suspended dust and high flow extraction systems.

High-pressure filter for dust

As a manufacturer of air extraction and filtration systems, with over 40 years of experience, we were contacted by a big company in the Modena area (Italy), a leader in the pharmaceutical industry, for the supply of a new high-pressure filter to be installed inside a dust extraction system.

After an inspection and a detailed analysis by one of our specialist technicians, we decided to supply our Poljet filter unit model F100/10 with circular construction. The air flow extracted within the company, laden with dusty material, reaches the Poljet F at high speed, where it is filtered through 100 highly efficient filtering bags. The clean air is then released into the atmosphere via a properly dimensioned exhaust chimney.

The dust retained by the high-pressure filter is discharged into the hopper and collected in a Big Bag, positioned inside a sealed metal container.

The high-pressure filter is also equipped with an overhead guard with a canopy, so that inspections and maintenance can be carried out in complete safety.

Filter clogging control systems

The Poljet high-pressure filter for dust is equipped with two digital control units for monitoring and cleaning the filtering bags.

• The GCS6P pressure gauge is used to check the clogging status of the bags and, in case of occlusion, it signals the need for maintenance.
• The Eco-Compact APC automatic cleaning unit, on the other hand, manages the compressed air cleaning system of the bags: a compressed air tank is installed in the filter lung, which, by means of timed air jets, causes the dust to detach from the filtering fabric of the bags and fall into the collection bag.

For the Poljet high-pressure filter, we have also provided a hopper fluidification system: by means of an auger and a timer, jets of compressed air are blown into the hopper to prevent the build-up of material that would obstruct the proper discharge of the filtered dust.

Why choose a high-pressure extraction system?

High-pressure extraction systems are the ideal solution for handling heavy dust and chips, typically produced during machining operations or in industrial environments where coarse materials are used.

The main applications include:

• machining with large rejects;
• cleaning workstations and machinery with heavy residues;
• localised suction at specific points in the production process.

Due to their ability to generate a strong concentrated extraction and to transport materials through small diameter pipes, these systems are a strategic choice to ensure a safe and compliant working environment.
