Dust and fume extraction systems for a wide range of industries
Cyclone Separators
Cyclone separators use centrifugal force to remove large dust particles from the air before they reach your primary filtration system. With a cyclone separator in place, your dust extraction system lasts longer and performs better. By separating larger debris first, you reduce wear and tear on your main filters including fewer blockages, cutting down on replacements and maintenance costs. Ideal for woodworking shops, factories, and sawmills, these systems handle heavy particles like wood chips and plastic swarf, preventing them from clogging finer filters.
Reverse-Flow Dust Collectors
Reverse-flow dust collectors are perfect for industries dealing with larger dust particles, such as timber manufacturing and processing. These systems use cleaning fans that periodically reverse the airflow, dislodging dust from the filters when the system is not in use. This automated cleaning process keeps your filters working efficiently without manual intervention. Designed to handle air volumes from 2,500m³/hr to 100,000m³/hr, these systems are suitable for a wide range of industrial applications.
Reverse-Pulse Dust Collectors
When dealing with fine dust, a reverse-pulse dust collector is the best choice. Our VC series, along with Camfil Dust Collection units, use high-pressure air pulses to clean filters, ensuring continuous operation without blockages. These systems are ideal for industries where fine dust accumulates, such as metalworking, pharmaceuticals, and woodworking. These units can be designed with cartridge or bag filters and be integrated with cyclone separators or positioned at the end of duct lines for maximum efficiency.
Bin Filling Systems
A well-designed bin filling system ensures efficient dust and waste management. Instead of relying on a simple bin under a dust collector or cyclone, our purpose-built systems use ducts, diverters, and conveyors to direct waste into large containers, such as shipping bins. This setup minimises manual handling and maximises storage capacity, reducing the frequency of bin changes.
Pneumatic Transport
Pneumatic transport systems move bulk materials efficiently between locations using high-pressure fans. Whether transferring waste from a hammermill, cyclone, or filter unit to a storage area, these systems ensure smooth, dust-free transport. By automating material movement, pneumatic transport reduces manual labour and improves workplace cleanliness.
Wet Scrubbers
For dust and fumes that traditional filters can't handle, wet scrubbers offer a powerful solution. These systems capture fine particles and gases, making them ideal for industries dealing with combustible dust, chemical fumes, or paint fume extraction. Wet scrubbers help you meet environmental and safety standards while improving air quality in your workplace.
Rotary Valves
A rotary valve plays a crucial role in dust extraction by acting as an airlock between different pressure zones. For example, it prevents air from escaping a dust collector while allowing dust to move into a waste bin. By maintaining proper airflow, rotary valves improve the efficiency of dust collection systems and reduce contamination risks. We manufacture our own rotary valves to ensure durability and reliability in demanding industrial environments.
Custom extraction hoods and manifolds
Dust collection hoods and machine manifolds ensure even airflow distribution across your equipment. A well-designed hood captures dust at the source, preventing it from spreading into your workspace. Each system is custom-made to match your machinery and extraction needs.
A dust or fume extraction system removes airborne particles, smoke, or gases from a workspace before they can be inhaled by workers. These systems use fans and ducting to capture contaminants at the source and pass them through filtration units, keeping the air clean and safe.
At Viking Ironcraft, we design and manufacture customised extraction systems that capture contaminants at the source and safely remove them from your workspace. This ensures better air quality, improved worker safety, and compliance with New Zealand health and safety standards.
Processes such as welding, grinding, sanding, cutting, and spraying release harmful airborne particles. Long term exposure can cause serious health issues, including asthma, lung disease, and other respiratory problems.
A properly designed extraction system protects workers, improves workplace conditions, and helps businesses meet regulatory obligations. Viking Ironcraft systems are engineered to deliver reliable airflow and filtration to keep your facility safe and compliant.
Yes, in many cases. New Zealand health and safety guidance requires employers to manage airborne contaminants and minimise worker exposure to hazardous dust or fumes. Engineering controls such as local exhaust ventilation, are considered one of the most effective ways to do this. (worksafe.govt.nz)
Viking Ironcraft can assess your workplace processes and design a system that helps you meet WorkSafe requirements while improving air quality for your team.
Dust and fume extraction systems are commonly required in industries such as:
- Metal fabrication and welding
- Manufacturing and engineering workshops
- Woodworking and joinery
- Paint and spray finishing
- Automotive repair and fabrication
- Food or powder processing
Each environment produces different contaminants, which is why Viking Ironcraft designs custom systems suited to your specific industry and process.
There are several system types depending on the contaminants being produced. These can include:
- Local exhaust ventilation (LEV) systems
- Source capture extraction arms
- Industrial dust collectors
- Wet scrubber systems for difficult fumes or particles
- Modular ducting systems
- Mobile extraction units
For example, wet scrubbers can capture very fine particles or chemical fumes that traditional filters cannot handle.
Viking Ironcraft designs systems using the right combination of technologies to ensure maximum efficiency and safety.
Yes. Most industrial extraction systems are custom-designed because every workspace produces different types and volumes of dust or fumes.
Viking Ironcraft specialises in tailored systems, designing ducting layouts, filtration units, and airflow capacity to suit your equipment, production processes, and workshop size.
The correct system size depends on several factors, including:
- The type of dust or fumes produced
- The number of machines or workstations
- Airflow requirements
- Workshop layout and ceiling height
- Compliance standards
Viking Ironcraft evaluates these factors and designs a system that captures contaminants efficiently without wasting energy or airflow capacity.
Yes. Cleaner air leads to healthier staff, fewer respiratory issues, and a more comfortable work environment. This often reduces downtime and improves overall productivity in industrial workplaces.
A well-designed system from Viking Ironcraft ensures contaminants are removed efficiently while maintaining a safe and productive workspace.
Regular maintenance is important to ensure consistent airflow and filtration performance. Maintenance can include:
- Checking filters and replacing them when needed
- Inspecting ducting for buildup or leaks
- Testing airflow performance
- Cleaning collectors and fans
Viking Ironcraft can design systems that are easy to maintain and provide guidance to keep them performing efficiently for years.
