The DCE Tornado Mk II Dust Collector is a compact high-performance reverse jet cartridge dust collector, specifically developed to meet the highest industry standards. Designed to handle process dust from varied industry sectors the DCE Tornado MK II is constructed in modular form for ease of installation. Comprised of 4 high-performance filter cartridges specifically tailored to suit individual dust & fume particulate.

Working Principle

  • In normal working operation, dust laden air enters the filter through the gas inlet box or open base of the unit dependent upon model designation and coats the outsides of the filter elements. The filtered air flows through the centre of the cartridges into the clean air plenum where it exits the filter via the fan set & acoustic silencer (fan ventilator type) or through a side outlet grille with cowl (vent type).
  • The filter elements are automatically cleaned with an electronic circuit board that activates the remote solenoids mounted on the end of each diaphragm valve. Upon activation of the solenoid the diaphragm valves open allowing a certain volume of compressed air through a blow tube with jet nozzles directing compressed air down the inside of each filter element.
  • The compressed air pulse - with the induced air added to it - flows through the filter element and filter media in the opposite direction to the normal airflow. The result is that the dust built up on the outer surface of the filter elements is blown off and falls into the collection hopper.
  • The air pulse lasts approximately 80-200 milliseconds after which the diaphragm valve closes and the filter elements become back online.


  • 4kW fan.
  • Extraction rate of 3,240M³/h.
  • With high cartridge performance and low noise levels, the DCE Tornado MK II is ideal for installations where the footprint is restricted.
  • Discharge silencer.
  • Furnished with 250mm dia Stuvex ATEX ST2 non-return valve. 
  • Rotolok rotary valve above the bin, 0.37kW.
  • 100 Litre dust collection bucket.
  • 4 New cartridges fitted.

What are Cartridge Dust Collectors?

Cartridge Dust Collectors a type of filter unit which is predominantly used in environments where space is at a premium. They can often maintain airflows which remain comparable to larger baghouse units.

Cartridge units provide larger fabric filter areas into a smaller place, use less filters and can be changed from the outside of the extractor, rather than having to access the unit internally, thus reducing filter replacement times and less environmental contamination issues for maintenance staff.

They are ideal for commercial and industrial environments, whose processes produce very fine-to- moderate dust-like powders, metalworking, woodworking, fume collection, thermal spraying, among other processes.

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. 

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.

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.
