Downflo® Oval Dust Collectors Provide Higher
Airflow with a Small Footprint on Concrete Dust
INDUSTRY: Architectural Concrete Products
PROBLEM: Old dust collectors with low airflow
SOLUTION: Donaldson® Torit® Downflo Oval (DFO) collector with Ultra-Web® catridge filters
When Butterfield needed a dust collection system that could handle particle sizes ranging from 10 to 500 microns. They chose two Donaldson® Torit® Downflo® Oval (DFO) self-cleaning cartridge dust collectors each containing eight Ultra-Web® cartridge filters.
The DFO design allows a 2.5% more airflow than traditional dust collectors, improved airflow path, and a 30% increase in pulse cleaning pressure. For Butterfield, this meant that only relatively small units were needed for the eight tanks. Inside the collectors, the Ultra-Web filter media is engineered to capture both large and very small dust particles. Since Donaldson® Torit® first introduced Ultra-Web® nanofiber catridges nearly 30 years ago, it has been continually advanced and perfected to deliver lower emissions, longer filter life, and greater cost savings.
The Donaldson® Torit® solution included:
- System design consultation
- Two DFO collectors with Ultra-Web®
- Ductwork from tanks and color blender
- Ex-Arm extraction arms for source capture at the blender
- Rotary valves enabling continuous flow of collected dust to drums for disposal
Butterfield Color reports being “very happy” with the performance of the DFO collection systems, the Ultra-Web® cartridge filters, and the installation.
