Ducon Cartridge Dust Collector

The cartridge dust collector Kompac Air by MDSJ is a dry filtration system used to purify air from suspended solid particles.

Advantages

The installation of the cartridge dust collector Kompac Air allows treatment of a wide range of pollutants, by ensuring the quality of the air in the production environment and protection for workers. Filter elements cleaning is managed by pressure drop reading, favouring a lower compressed air consumption and an increased life for cartridges. The cartridge dust collector Kompac Air has a high filtering surface, it is compact, easy to handle and transport and quick to install.

How it works

The dusty air is conveyed to the cartridges from the outside to the inside, depositing the impurities on the external part of the filter elements and in the collecting hopper. A compressed air jet, stored in a special tank, is injected cyclically in the cartridges, creating a wave of shaking able to detach and topple the particles deposited on the external part of the cartridges.

Standard equipment for all configurations

  • Filtration chamber

  • Hopper with support legs

  • Maintenance door

  • Cleaning pneumatic system of the cartridges controlled by differential pressure switch

  • Optional equipment for all configurations


Staircase and walkway to access the maintenance door

  • Tank cover

  • Control panel cover

  • Pressure regulator

  • Electrical panel

The cartridge dust collector Kompac Air is modular in its main parts directly by the costumer according to specific needs and type of use. The different configuration in the catalogue comes from the mix of the following variants:

Type of inlet of dirty air (presence or not of pre-filtering chamber for the collection of the biggest dust, it has the task of protecting the cartridges from excessive load of pollutant) Type of dust discharge (collection bin; rotary valve for continuous discharge; combined action of screw and rotary valve) Means of access to the maintenance door and its placement Possibility to use in ATEX area (presence or not of components suitable for potentially explosive mixtures)

Cartridge Dust Collector

Configuration with dirty air inlet directly into the hopper, frontal extraction system of the filtering elements, dust discharge in a special bin placed under the hopper.

Optional equipment for the configuration

Deflector in hopper

Fan + soundproof box to lower the noise produce by the engine (on the top or on the ground)

Operating Principle

  • Dirty air enters the unit and passes through purpose-woven filter bags that capture the dust.
  • Particulates are held on the outside of the bags while clean air is sent to atmosphere or to a recovery line.
  • Once differential pressure reaches the set point, solenoid valves fire a brief burst of high-pressure air into each bag (the jet-pulse effect); the shock wave drops the dust cake into the hopper.
  • Cleaning rotates by compartment - one cell cleans while others continue filtering; airflow is uninterrupted.

  • Polypropylene (PP) - acid-resistant, ≤90°C, for chemical environments.
  • Acrylic - humid and acidic conditions, ≤125°C, food and fermentation.
  • Nomex (m-Aramid) - high temperature, ≤200°C, cement clinker and metal processes.
  • P-84 (Polyimide) - hottest gases, ≤260°C, fly ash and waste incineration.
  • PTFE (Teflon) membrane - chemical resistant + clean release, ≤280°C, pharma and precision lines.
  • Fiberglass - high temperature (≤280°C), aggressive gas environment.
  • Anti-static media - explosive dust risks (ATEX compliant) - aluminum, magnesium, organic dust.

Industries Served

  • Cement and gypsum - clinker, raw mill, coal mill filtration.
  • Iron-steel and foundry - furnace emissions, cupola, casting ladle dust.
  • Metallurgy and aluminum - smelting furnace, slag handling.
  • Food and feed - flour, sugar, coffee, grain dust (ATEX compliant).
  • Chemicals and pharma - reactor outlet dust control, precision lines.
  • Mining crushing/screening - ore and aggregate plants.

  • Plastics and recycling - PVC, PET, granule drying lines.

Advantages

  • High efficiency: up to 99.9% dust capture, including very fine particles.
  • Continuous operation: bag cleaning runs while production continues, minimizing downtime.
  • Low operating cost: long-life filter bags and optimized compressed-air consumption.

Frequently Asked Questions

What is a jet-pulse filter?

A jet-pulse filter (baghouse) captures industrial dust on filter bags and cleans them automatically with bursts of compressed air. It delivers 99.9% efficiency with online cleaning that does not stop production.

Is a jet-pulse filter the same as a baghouse?

Baghouse is the family term; jet pulse is the most common automatic pulse-jet cleaning architecture in that family. Other baghouse types use reverse-air or shaker cleaning.

Which bag media should I choose?

Polyester for standard (≤135°C), polypropylene for acidic conditions, Nomex for high temperature (≤200°C), P-84 or PTFE membrane for hottest gases (≤260°C), anti-static media for combustible dust.

What is the capacity range?

DUCON KM series is modular from 1,000 m³/h up to 1,000,000 m³/h. Filtration area scales between 10 and 12,500 m².

What is the difference between polyester and Nomex bags?

Polyester ≤135°C, most economical, ideal for dry dust. Nomex ≤200°C, high-temperature resistance, preferred in cement clinker and metal processes. Cost difference is typically 3-5×.

When does the system clean itself?

When differential pressure reaches the set point (typically 100-150 mmH2O) solenoid valves auto-trigger pulse cleaning. Production never stops — one cell cleans while others continue filtering.

Is ATEX required for jet-pulse filters?

In processes with explosive dust (aluminum, magnesium, flour, sugar, organic) ATEX zone classification and compliant equipment are mandatory. DUCON KM series is optionally ATEX compliant.

How often are filter bags replaced?

2-4 years under standard conditions. Abrasive dust, high temperature, or chemical load can shorten to 1-2 years. Correct bag selection and A/C ratio directly affect life.

How much compressed air does it consume?

Pulse cleaning uses 6-7 bar compressed air. Typical consumption is 0.1-0.3 Nm³/min/m² of filter area; on-demand cleaning minimizes it.

Which industries use jet-pulse filters?

Cement, iron-steel, metallurgy, food, chemical, pharma, mining, glass, ceramic, waste incineration, wood, and plastic recycling — almost every industrial dust line.

Who is the jet-pulse filter manufacturer in Turkey?

MDSJ Process designs, manufactures, installs, and commissions jet-pulse baghouse filters (DUCON KM series) in Turkey under the DUCON brand (MDSJ owns the DUCON trademark rights for Europe, Asia, and Turkey). Active since 1986.

What emission limits are achievable?

With correct design and bag selection, emissions <10 mg/Nm³ are achievable. Safely meets EU and Turkey environmental limits (typically 20-50 mg/Nm³).
