Maintaining clean air in industrial workplaces is essential for employee wellbeing, equipment reliability, and regulatory compliance. Dust and dry smoke created during manufacturing processes can quickly spread through workshops, reducing visibility, contaminating machinery, increasing fire risks, and exposing workers to harmful airborne particles.
Jemtech supplies advanced dust and dry smoke extraction systems designed to remove contaminants at source, improve air quality, and create safer, more productive environments. Their industrial extraction range includes compact workshop units, self-cleaning cartridge filters, high-load bag systems, modular collectors, cyclone pre-separators, and ATEX-rated solutions for explosive dust environments. Jemtech states some systems can capture up to 99.95% of pollutant particles while helping reduce emissions below 1mg/Nm³.
Dust and dry smoke extraction is the process of capturing airborne particles, fumes, and smoke created during industrial processes before they spread into the workplace. These systems typically use hoods, ducting, filters, and fans to remove contaminants at source.
Dust usually consists of solid particles generated by cutting, sanding, grinding, weighing, or transferring materials. Dry smoke is made up of extremely fine airborne particles created by heat processes such as welding, laser cutting, soldering, or thermal treatment.
Without extraction, airborne dust can:
• Affect employee health
• Create slip hazards when settled
• Damage machinery
• Contaminate finished parts
• Increase cleaning costs
• Cause downtime
• Raise fire or explosion risk
Yes. Dry smoke particles are often extremely fine and can penetrate deep into the lungs. Depending on the material being processed, smoke may contain hazardous compounds, metal particulates, or irritants.
Common sectors include:
• Precision engineering
• CNC machining
• Metal fabrication
• Welding shops
• Pharmaceutical manufacturing
• Food production
• Woodworking
• Recycling plants
• Battery manufacturing
• Electronics assembly
Typical dust-producing processes include:
• Grinding
• Polishing
• Sanding
• Cutting composites
• Mixing powders
• Bag emptying
• Material transfer
• Shot blasting
• Wood machining
Dry smoke is commonly generated by:
• Welding
• Laser cutting
• Plasma cutting
• Soldering
• Brazing
• Furnace operations
• Thermal spraying
Source capture places an extraction hood, arm, enclosure, or inlet close to where contaminants are generated. This is usually the most effective approach because pollutants are removed before they disperse.
That depends on:
• Dust type and particle size
• Volume of contaminants
• Number of machines
• Continuous or intermittent use
• Required airflow
• Space available
• Whether dust is explosive
• Maintenance preferences
A site survey is normally the best starting point.
Jemtech’s range includes:
• Pulsatron Compact – self-cleaning cartridge filters
• Pulsatron Compact Mini – compact unit for smaller workshops
• Pulsatron H – modular high-airflow collectors
• Bag Compact – medium/light duty applications
• HJL Bag / HJL Cart – high dust loads and continuous operation
• PC Cyclone – centrifugal pre-separator
• ATEX models for explosive dust risks
A self-cleaning collector automatically cleans filter media using pulse-jet or similar technology, helping maintain airflow while reducing manual maintenance and downtime.
A cyclone uses centrifugal force to separate heavier dust particles before air reaches the main filter. This extends filter life and improves efficiency.
ATEX systems are designed for explosive atmospheres where combustible dust may ignite. They include safety features suited to hazardous environments.
Some metal dusts, flour dust, wood dust, plastics, chemicals, and fine powders can be combustible. A formal dust risk assessment is recommended.
Yes. Cleaner air can reduce contamination on machines, controls, sensors, and finished components, helping improve uptime and product quality.
It depends on:
• Usage hours
• Dust loading
• Filter type
• Maintenance schedule
• Production environment
Self-cleaning systems often extend service intervals.
Yes. Centralised extraction systems can be designed to connect multiple workstations or machines, depending on airflow demand and layout.
Sizing is based on:
• Airflow (m³/h) required
• Number of extraction points
• Static pressure losses
• Dust characteristics
• Duty cycle
Incorrect sizing can reduce capture performance.
Yes. Capturing contaminants before they settle often reduces housekeeping time, labour, and secondary clean-up.
Yes. Proper Local Exhaust Ventilation (LEV) systems can help businesses meet workplace air quality and health & safety responsibilities when correctly specified, maintained, and tested.
Yes. Jemtech promotes supply, installation, maintenance, servicing, LEV testing, air monitoring, and emergency support services.
• Bag filters are often suited to higher dust loads or coarse materials.
• Cartridge filters are often ideal for fine dust with compact footprints and high filtration efficiency.
Look for:
• Dust settling quickly
• Poor visibility
• Odours or smoke lingering
• Frequent filter blockages
• Worker complaints
• Dirty machinery
• Reduced airflow
