Ind Dust Fume Extractor – Dust Extractor
AD Cyclone

The AD Cyclone from Donaldson BOFA is a high-efficiency inline cyclone pre-filter unit designed to capture large particles and particulate debris generated during laser processing. Positioned between the laser workstation and the main fume extraction unit, it serves as the first line of defence, significantly reducing filter loading on downstream extraction systems.
Engineered for demanding laser cutting, marking, and engraving applications, the AD Cyclone uses centrifugal air separation to remove heavier contaminants from the airstream. This proactive filtration step dramatically extends the service life of HEPA and carbon filters in the main extraction unit, reducing operational costs and system downtime.
Distributed in India by United Spectrum Instruments, the AD Cyclone comes with full integration support, system optimisation consultancy, and maintenance services tailored to diverse industry needs.
Understanding AD Cyclone
The AD Cyclone is engineered as a pre-filter that uses cyclonic action to separate and contain large dust particles. Positioned before the main Donaldson BOFA extraction system, it ensures that only finer particulates pass through to the primary filters. This significantly extends filter life, reduces maintenance downtime, and improves system efficiency. Designed for heavy-duty industrial use, the AD Cyclone provides a practical and cost-effective solution for businesses dealing with demanding dust and fume applications.

FAQs
What is the AD Cyclone, and what does it do?
The AD Cyclone is a pre-filtration unit that uses centrifugal force to remove large airborne particles before they reach the main laser fume extractor. It helps extend the life of HEPA and carbon filters.
Does it require electricity to operate?
No, the AD Cyclone operates entirely passively. It uses the airflow generated by the connected extraction system and does not require a power connection.
What laser applications is it best suited for?
It’s ideal for high-dust laser processes such as engraving wood or cutting acrylic, marking powder-coated metals, or handling mixed-use environments.
How is the AD Cyclone installed?
It is installed inline between the laser workstation and the main fume extraction system. Installation is simple and doesn’t require complex controls.
How do I maintain the unit?
Maintenance involves occasional manual emptying of the debris collected inside the unit. No tools are needed, and intervals depend on usage volume.
