Overview
With their high-efficiency cartridge filters and easy installation, the DFPRE units are a compact and powerful dust collection solution.
When sold with an optional HEPA afterfilter, all models achieve an extremely high filtration efficiency of 99.97% on 0.3-micron particles.
Easy Installation
- Ships pre-assembled for streamlined set-up
- Pre-wired fan and controls
- Protective junction box included
- Compressed air regulator
- Low side inlet for convenient duct connection to OEM equipment
- 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.
Peak Performance
- Enhanced airflow design directs incoming air to the inlet dropout plate for reduced filter loading
- Enhanced media surface area and pulse cleaning supports long filter life
- Increased airflow per cartridge results in a lower cost per CFM
Enhanced Spark Reducing Inlet Mitigation Options
Available with the spark-reducing inlet that, when used as part of an overall fire mitigation strategy, can help reduce the risk of a spark entering the dust collector by directing the airstream through a tortuous path.*

DFPRE 4, 6 & 9 Features
Engineered to Excel
The DFPRE dust collector utilizes 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 easy. 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 fast, while the timely pulse cleaning adds to filter life and performance.
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® fine fiber 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.
With its more efficient cartridge filters and advanced downward airflow, the DFPRE requires fewer filters for the same filtration power, resulting in:
- Reduced filter replacement costs
- Reduced maintenance
- Reduced floor space requirements
