What is a Jet Pulse Filter?

A Jet Pulse Filter (baghouse) is an industrial dust collection system that eliminates 99.9% of dust and particulates generated during heavy industry operations like cement, steel, mining, and food processing by using compressed air shocks.

  • Working Principle: As dirty air passes through the exterior of filter bags, dust is collected on the surface while clean air is exhausted out.
  • Automated Cleaning (Jet Pulse): High-pressure compressed air is injected into the filter bags for fractions of a second via timed valves, knocking the accumulated dust cake into the bottom hopper.
  • Advantages: Offers continuous 24/7 operation, self-cleans without interrupting the system, and extends maintenance intervals.
  • Applications: Pneumatic conveying lines, silo filling stations, fly ash filtration, and crushing-screening facilities.

DUCON KM Chamber Jet Pulse Bag Filters

Jet pulse chamber bag filters are offered with 2 chambers to 24 chambers cylindrical bags for high flow and difficult to clean dust filtration. Bag sizes are 130 diameter, 160mm and lengths are produced from 3 to 10m. We have a land production of 50000 m3/h to 6000000m3/h. The most important feature is that the compartment can be closed and maintenance can be done without stopping the system. Body structures are produced in carbon steel, corten stainless steel, externally reinforced and resistant to 80 mb vacuum according to operating characteristics.

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.

  • Pulse pressure: 6-7 bar (compressed-air supply).
  • Air-to-cloth (A/C) ratio: 0.8 - 2.5 m/min (per dust characteristics).
  • Differential pressure (ΔP): 100-150 mmH2O typical operating point.

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).
