Overview
The DFPRE (Downflo Evolution Pre Assebled) Portable fume collector is designed to meet the demands of modern metal fabrication, which include innovative approaches to handle new techniques and applications, increased production requirements, and stricter regulations. To address these evolving needs, filtration solutions are required to seamlessly integrate into different layouts and workflows, effectively removing process emissions and helping create a clean workplace.
Donaldson understands the critical need for compact, convenient, and reliable filtration systems during production. That's why we've developed the DFPRE 1 Series, a comprehensive solution designed to provide optimal uptime and support operators’ safety efforts.
The DFPRE Portable is not only easy to install, maintain, and operate but also delivers superior filtration performance. Specifically engineered with welding and finishing operations in mind, this series offers seamless integration. Simply connect its single-phase 230V AC power source, and you're ready to start working.
What sets the DFPRE Portable apart is its unmatched versatility. You have the option to connect compressed air solely during cleaning phases, providing continuous filtration quality without compromising the welder's working comfort. Equipped with renowned triagonal cartridge filters featuring Ultra-Web® Fine Fiber media and efficient pulse cleaning, it provides peak performance and helps reduce operational expenses for both continuous and high-emission applications.
Features
Plug-and-Play Operation
The DFPRE Portable fume collection system arrives fully assembled for effortless installation and operation. It operates using single-phase electric power and does not require an always-on compressed air connection at the workstation, thereby reducing complexity and enhancing flexibility and mobility. Additionally, the absence of ductwork simplifies the installation process, saving both time and resources while providing optimal performance.
- Plug-and-play with single-phase electric power
No need for a compressed air connection at the working station
No ductwork required*
Local regulations may restrict air recirculation, and if so, ductwork might be required for extraction.
Source Capture that Supports Air Recirculation or Extraction
The choice between source and ambient capture depends on the specific application and the physical limitations of the facility. Source capture is particularly suitable for environments with highly toxic fumes, preventing them from lingering in the breathing zone or spreading throughout the facility, especially in high-volume fume applications. The DFPRE offers a solution that combines high efficiency, flexibility, and mobility.
Fumes are captured before reaching the worker’s breathing zone and before they are dispersed throughout the workshop
Choice between Louvre or Flange outlet plates for air recirculation or external evacuation*
360-degree arm rotation and mobile collector to enable workers to smoothly reach their optimized working position
Up to 2 extraction arms can be used simultaneously for concurrent work
Ready for Heavy Duty
The DFPRE Portable fume collector, equipped with Donaldson's industry-leading Ultra-Web® fine fiber filtration technology (MERV 13), ensures efficient filtration even during continuous work on very high emissions applications, offering optional HEPA filters for situations where workers are directly exposed to recirculated air, along with pulse cleaning operation for unmatched extraction performance and extended filter lifespan.

The pulse cleaning operation provides unmatched extraction performance and extended filter lifespan.
Total extraction capacity with two extraction arms is up to 1950m³/h
Easy Maintenance
Regular maintenance of dust and fume collectors is essential to ensure optimal performance. The DFPRE 1 is equipped with controller that alerts you when cleaning is necessary. Once connected to compressed air, the pulse cleaning system delivers exceptional cleaning performance, enhancing filtration capacity without compromising filter lifespan or increasing compressed air consumption.
Manual cleaning mechanism with ΔP indicator and push button
Compressed air connection only required during offline cleaning
Tool-free, simple and quick filter changeouts
Cost Efficient
The DFPRE Portable fume collector features efficient pulse cleaning technology that extends the life of the filters, helping save you time and money on replacements. By combining Ultra-web media with our unique triagonal filter shape, this collector achieves long filter life and helps provide cost savings compared to other cartridge types. But that's not all. With on-demand pulse cleaning, this system reduces compressed air consumption to just 75L/min per cleaning sequence, providing efficient operation without unnecessary waste.
