Downflo Evolution Pre-Assembled Small – DFPRE
Easy to Install Dust Collector Maximizes Production Uptime
The DFPRE series of collectors was designed as a packaged system to answer customer demand for a compact, convenient, and reliable filtration system that can help maximize production uptime.
DFPRE Small Series
With their small footprints, high efficiency cartridge filters, and easy-to-connect ducting, the DFPRE 2 and 3 offer a compact and efficient dust collection solution to help achieve maximum performance and production uptime.
Easy Installation
- Ships pre-assembled for streamlined set-up
- Pre-wired fan and controls
- Includes protective junction box
- Compact design provides simple handling
- Clamp-together Easy-Duct™ connections don’t require special tools
Adaptability
Suitable for a wide range of applications with options including:
- HEPA afterfilter to achieve higher filtration efficiency: 99.97% on 0.3 micron particles
- 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
- 5-gallon Sealed Drum Kit which offers a simple and cost-effective connection for combustible dust applications
- Spark Reducing Inlet: When used as part of an overall fire mitigation strategy, it reduces the risk of a spark entering the dust collector by directing the airstream through a tortuous path.*
*Intended for use in applications with an increased fire risk and can be used as part of an overall fire mitigation strategy. No single spark mitigation device, including the Spark Reducing Inlet, can guarantee the elimination of all sparks and ignition sources from entering the dust collector. Please contact your Donaldson sales representative to discuss additional fire mitigation strategies as necessary.
Maximized Performance
- Enhanced airflow design directs incoming air to the inlet dropout plate for reduced filter loading
- Enhanced media surface area and pulse cleaning adds to filter life
- Increased airflow per cartridge results in a lower cost per CFM
Engineered to Excel
The DFPRE 2 and 3 utilize natural downward airflow for increased filtration performance. By ducting the dirty air into the collector from above the filters, the downward airflow forces heavy particulate from the airstream into the hopper.
The collector’s horizontally mounted filters make filter changeouts easier and even help limit exposure to dust during the process. The filter orientation also contributes to reduced compressed air usage since most of the heavy particulate has already found its way to the containment vessel.
The unit’s pre-wired fan and controls help take you from installation to operation faster, while the timely pulse cleaning adds to filter life and performance.
Applications
- Metal Manufacturing
- Chemical & Petroleum Products
- Pharmaceutical
- Metal Grinding
- Plasma Cutting
- Laser Cutting
- Welding
- Abrasive Blast
- Plastic
Industry-Leading Filtration Design
The 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
