AF8000-22000-L Dust Extraction System

Advantages of Austedan Fabrications Reverse Pulse Dust Extractors

The Model AF8000-22000-L is a high-capacity dust extraction system, designed to meet the rigorous demands of large-scale industrial environments. Capable of handling air volumes ranging from 8,000 to 22,000 cubic meters per hour (m³/hr), this model is a powerhouse in managing and controlling dust, fumes, and coarse particles across a variety of industrial applications.

The Model AF8000-22000-L Reverse Pulse Dust Extractors System

This system's capacity range positions it as an ideal solution for industries that generate a high volume of particulate matter, such as mining, heavy manufacturing, and large woodworking facilities. Its ability to efficiently process a wide range of dust types—from fine particles to larger debris—makes it exceptionally versatile. This versatility ensures that regardless of the specific dust composition, the Model AF8000-22000-L can effectively capture and contain it, thereby maintaining a clean and safe work environment.

The design of the AF8000-22000-L emphasises robustness and reliability, ensuring that it can withstand the continuous, heavy-duty operation typical in large industrial settings. By effectively removing dust and particulates from the work environment, this system not only enhances the air quality but also contributes significantly to the protection of workers' health and the maintenance of machinery.


The implementation of such a comprehensive dust extraction system as the AF8000-22000-L can be integral in ensuring compliance with strict occupational health and safety regulations. Investing in this model demonstrates a commitment to maintaining the highest standards of workplace safety and environmental care, making it a strategic choice for businesses aiming to prioritise employee well-being and operational efficiency.

  • What sets us apart from the rest?

    • All systems built with large inbuilt central pre-separation chamber which aids filter life and means dust is distributed into multiple hoppers evenly. The pre-separation chamber is a low velocity central part of our dust extraction where gravity and a very low downdraft velocity forces heavier particles and high dust load to be dropped out of the airstream when the air turns twice before coming into the filter area. This reduces the dust load onto the filter bags thus making the cleaning system more efficient and in turn increasing the life of the filter bag. Over 23 years of building dust collectors we have never had a dust collector bag fail by premature wear or large foreign items imploding into our bags. In some cases extending life by 5 – 6 years over some of our oppositions collectors.

    • We offer conservative air to cloth ratios and fabric selection for maximum capture of pollutants which in turn gives longer bag life, lower running costs and better emissions.

    • Our filter bags have snaptex cuffs which require no tools to replace our filter bag and are accessible from within the plenum above, which means “No Confined Space Work” or permits are needed for filter bag changes. This is also a safer and cleaner operation than dust extraction which have the filter bags changed from within the dirty area.

    • Our systems work under negative pressure where the fan is on the clean side which means no product or waste ever goes through our fan impellors, which in turn will never go out of balance, wear out prematurely or get broken impellors.

    • Our extractors are fabricated from 3-5mm fully welded mild steel construction and work under a negative pressure so they never leech dust out of the joins and seals,  Unlike some of our competitors positive pressure, bolt together, light gauge sheet metal dust collectors.
    • Our Hopper angles are designed to help prevent against product hang-up and are minimum of 60° UNA.

    • Inclined tops on our Dust Extractor.

    • prevent water lying on top thus reducing premature corrosion.

    • All Collectors are abrasive blasted before being painted by industrial painters in 2 Pak epoxy paint.

    • We offer full Turnkey systems including customisation, fabrication, installation and after-sales service to suit all customers specific requirements. 

  • Made to suit customer specific applications covering

    • Location issues 

    • Nature of dusts 

    • All waste dust discharge applications catered for 

    • Several waste bin options available
