Overview
With high-efficiency cartridge filters and easy installation, the DFPRE units are a compact and powerful dust solution. They feature a customizable design available in various sizes and configurations, capable of operating across a broad airflow range.
Easy Installation
- Ships pre-assembled for streamlined set-up
- Pre-wired fan and controls
- Protective junction box included
- Compact design provides for simple handling
- Clamp-together Easy-Duct™ Inlet connections that do not require special tools
Flexible & Configurable
- With its multitude of configurations and adaptable design, the DFPRE is designed to fit site specific requirements, making it suitable for a wide range of applications.
- Multiple integrated fan options to tailor the operating airflow and static pressure to your unique process needs.
- Side-mounted explosion vents or flameless vents to provide a complete and robust package for a variety of combustible dust applications.
Compatibility with combustible dust depends on local regulations. Certain products may not be suitable for combustible dust applications in some locations Contact your Donaldson sales representative to discuss additional fire mitigation strategies as necessary.
Maximised Performance
- Enhanced airflow design directs incoming air to the inlet dropout plate for reduced filter loading.
- Enhanced media surface area and pulse cleaning maximises filter life.
- Increased airflow per cartridge results in a lower cost per CFM.

Industry-Leading Filtration Design
Our horizontally mounted triagonal filters – made with industry-leading Ultra-Web® fine fiber technology – have more filter media at the bottom of the cartridge so pulse-cleaning energy directs the ejected dust toward its ultimate destination – the containment vessel.
Ultra-Web filtration technology features a layer of fine fibers (0.2 - 0.3 microns in diameter) on the surface of the media to capture sub-micron contaminants. This makes the dust cake come off easily during automated cleaning cycles, ensuring cleaner air longer.
With its more efficient cartridge filters and advanced downward airflow, the DFPRE 2 and 3 require fewer filters for the same filtration power, resulting in:
- Reduced filter replacement costs
- Reduced maintenance
- Reduced floor space requirements
