DFPRE Cartridge Dust Collectors

The DFPRE Series was designed as a turnkey system to answer the industry demand for a compact, convenient and reliable filtration system that can maximize production uptime. The result is a highly adaptable, modular and easy-to-install dust collector with unrivaled filtration performance – delivering operational confidence in today’s advanced manufacturing environment.

Built on more than 20 years of successful performance of the DFPRO, our next generation DFPRE and fume collector series offer a more efficient, compact, and economical solution that can effectively support continuous manufacturing processes. This compact unit is easy to transport, relocate and install: it comes pre-assembled and requires minimal set-up.

Industry-Leading Filtration Design

The DFPRE Series is equipped with our unique trigonal Evolution cartridges that are specifically designed for improved pulse cleaning, increased airflow per cartridge, and superior performance. With its more efficient cartridge filters and advanced downward airflow, the DFPRE system has fewer cartridges for the same filtration power, reducing filter replacement costs, maintenance, and floor space requirements.

Positioning more filter media at the bottom of the cartridge, the trigonal shape allows for more dust to be accumulated on the bottom of the filter and is helped by gravity to achieve superior pulse cleaning performance, less energy consumption, fewer filter changes, and reduced maintenance/downtime.

Next-Generation Design for Superior Performance

The DFPRE Series feature Donaldson’s latest solutions that include enhanced downward airflow design, triagonal filter shape, and industry-leading filtration medias designed to maximize filtration performance.

Step 1: Dust Management at Source

Dust generated at the source is pulled into a pre-separator to effectively mitigate the following issues: reducing dust load to acceptable levels, minimizing the abrasive effects of dust, mitigating the risk of fire, and ensuring even distribution of airflow.

Step 2: Efficient Contaminant Extraction

Contaminated air is drawn through the collector by the fan, where airflow is directed, causing heavier particulates to fall directly into the hopper.

Step 3: Precision Filtration Process

The cartridges effectively capture fine particulates, allowing only clean, filtered air to pass through into the clean air chamber. With efficient pulse cleaning, it helps increase the lifespan of a cartridge, allowing you to lower your operational costs due to energy consumption, filter changes and maintenance.

Step 4: Final Air Treatment and Discharge

Cleaned air is discharged through the air outlet for either recirculation indoors or evacuation outside, with the option for additional filtration, such as a secondary HEPA filter, to ensure optimal indoor air quality in certain scenarios.
