A self-contained heavy duty continuously rated collector with everything needed to begin collecting dust, this unit comes complete with fan, a reverse jet pulse cleaning system, explosion relief panel and control panel.

Operating Principle

  • The fumes emitted from cutting operations are aspirated and conveyed through ducts to the dust collector through a pre-chamber, favouring the separation of coarse particles by decantation.
  • With the remaining lighter particles in suspension, the flow passes through the cartridge compartment, depositing the pollutant outside the cartridges.
  • The clean air can thus be expelled from the dust collector head via an exhaust fan.
  • An electric panel controls the cleaning of the cartridges. The dust falls and collects in the hopper below.

Construction Features

  • Lower support structure.
  • Collection hopper for the collected dust with automatic membrane discharge.
  • Filter body for containing the filter cartridges.
  • Filter cartridges made of heat-sealed non-woven polyester fabric (PES).
  • Full-immersion type washing air distribution manifold with built-in solenoid valves and banks of nozzles.
  • Centrifugal fan for fume intake and clean air expulsion.
  • Electronic cleaning cycle regulation panel with Delta p detector and economizer.
  • 50 Litre dust collection bucket.


  • 'Sovem' Motor 7.5kW, 10 Hp. 
  • 14 Amps.
  • 2900 rev/min.

Design Features

  • 6 Cartridge filters a total of 126m² filter area.
  • Air outlet: 300 x 300mm approx.
  • Air Inlet: Ø300mm
  • Versatility to suit a variety of dust collection applications.
  • Easy maintenance.
  • Quick-release bucket levers allow for easy removal and maintenance of the bin.
  • Inlet deflector knocks down larger particles into the hopper, reducing bag abrasion and increasing bag filter life.
  • Heavy-duty cartridge filters, DRC1023.

How do Dust Extractors Work?

Dust collection systems work in a variety of different ways but all have general principles in common. They draw process dust and particulates from the air through a filter that first captures and separates the matter, and then discharges decontaminated air back into the workplace or environment.

Dust extractors are used in many different and varied industries and so different demands are made of them; however all have common components such as a blower (or fan), dust filter, filter cleaning system, dust container and dust removal system.

Five common types of dust collection equipment are fabric filter baghouses, inertial separators (like mechanical cyclones), cartridge collectors, wet scrubbers, and electrostatic precipitators.

Importance of Dust Extractors

Dust in the workplace can affect product quality and employee´s health. Having a dust-free environment is essential to the health and safety of the workforce. Not only does it affect the health of employees but the dust covers the equipment affecting production processes and quality of the products. 

Capturing the dust at the source prevents it from spreading, done by using a dust extractor system to facilitate the important housekeeping to avoid it from accumulating.

Importance of Explosion Panels in a Dust Extractor

As extraction systems suck in air in concentrated volumes, the risk of explosive dust igniting is greater; therefore precautions are required to control the risk. A dust extractor with explosion panels installed will have these panels located in the areas where the dust is most likely to combust, controlling the explosion so it ignites in the area that has been constructed to withstand the impact without damaging the extractor itself.

What are Reverse Pulse Jet Dust Collectors?

Reverse Pulse Jet Dust Collectors use a jet of air to clean dust from the collector's filters. Commonly used in pleated filter cartridge units, the filters are cleaned by a series of rapid, high-pressure air jets which sends a blast or shock of air through the reverse side of the filters. In effect this shakes the collected dust from the filters into the dust collection system. The rapid reverse pulse of air allows for continuous operation with the fan running and has high collection efficiencies.

Reverse Pulse Jet Dust Collectors are the most common type of industrial dust collectors and can handle a wide range of temperatures and pressures. They are commonly used in manufacturing environments where large volumes of solids are processed, such as mineral production, food processing and metal fabrication industries.

A control unit sets the variables such as time duration between pulses, length of pulse and pressure.
