Dust Extraction

Our industrial dust extraction services include designing, installing, and maintaining advanced systems to efficiently capture and filter airborne dust. We ensure compliance with safety regulations, improve air quality, protect equipment, and promote a healthier, cleaner working environment for various industries.

An industrial dust filtration unit is designed to remove dust and particulate matter from air or gas streams in industrial settings, ensuring a clean and safe working environment and preventing contamination.

These systems work by capturing dust particles using filters or separation mechanisms.

Here’s a breakdown of the types of units we can supply and how they typically work:

1. Air Intake

• Dusty air enters the unit: The dust-laden air or gas is drawn into the filtration unit via ducts, hoods, or inlets. This air is often transported using blowers or fans.

• Pre-filtration (optional): Some systems include a pre-filter to capture larger particles before they reach the main filtration unit.

2. Filtration Mechanism

The filtration process can vary depending on the type of system:

Baghouse Filters

• Fabric filters: Dust-laden air passes through fabric filter bags made of woven or nonwoven materials.

• Dust capture: Dust particles are trapped on the surface of the bags while clean air passes through.

• Pulse-jet cleaning: A periodic burst of compressed air cleans the bags, dislodging the dust, which falls into a collection hopper.

Cartridge Filters

• Pleated filter cartridges: These have a large surface area and are made of materials like polyester or cellulose.

• Filtration: Dust is captured on the surface of the cartridges, and clean air flows out.

• Cleaning: Similar to baghouses, compressed air or vibration is used to clean the filters.

Cyclonic Separators

• Cyclone effect: Dust-laden air enters a cylindrical chamber and spins in a vortex.

• Separation: Centrifugal force pushes heavier particles to the chamber walls, where they fall into a collection hopper, while clean air exits through the top.

Electrostatic Precipitators (ESPs)

• Electrical charge: Dust particles are charged as they pass through an electric field.

• Collection: Charged particles are attracted to oppositely charged plates, where they stick. These plates are periodically cleaned to remove the dust.

Wet Scrubbers

• Liquid medium: Dust-laden air is sprayed with water or another liquid.

• Particle capture: Dust particles adhere to liquid droplets and are removed from the air stream.

3. Dust Collection

• Hopper or bin: Dislodged dust falls into a hopper or collection bin for easy disposal or recycling.

• Automated discharge: Some systems include automated conveyors or augers to transport the collected dust.

4. Air Exhaust

• Clean air release: After filtration, the clean air is exhausted back into the workspace or vented outside, complying with environmental regulations.

• Optional secondary filtration: HEPA or ULPA filters may be added for finer filtration if needed.

5. Monitoring and Maintenance

• Sensors: Systems often include sensors to monitor air quality, pressure drop (indicating filter clogging), and system performance.

• Regular maintenance: Filters, collectors, and cleaning mechanisms require periodic maintenance to ensure efficiency.

Providing an ATEX-Compliant System

• To deliver an ATEX-compliant dust extraction system, our process ensures safety and reliability in explosive atmospheres:

  1. Assessment and Consultation
     We start by evaluating the customer’s site to identify ATEX zones and assess the risks of explosive dust. This includes understanding the materials involved, environmental conditions, and workflow.

  2. Customised System Design
     Based on the assessment, we design a tailored system using ATEX-certified components, including explosion-proof fans, filters, ducting, and control panels. All designs comply with ATEX directives and industry standards.

  3. Installation and Integration
     Our experienced technicians install the system, ensuring seamless integration with existing processes. We implement explosion isolation devices, such as venting panels or flameless venting, to mitigate risks.

  4. Testing and Certification
     Before handover, we conduct rigorous testing to confirm compliance with ATEX requirements. We provide detailed documentation, including ATEX certification, operational manuals, and maintenance guidelines.

  5. Ongoing Support
     We offer maintenance, inspections, and LEV testing to ensure the system remains efficient, safe, and compliant over its lifecycle.

  By prioritising safety and compliance, we provide robust ATEX systems that protect personnel, facilities, and operations in hazardous environments.
