The quest for ‘compact dust collectors in the industrial filtration arena has led to the increased use of filter cartridges. Amongst these dust collectors is one developed by a competitor using PowerCore’ filter cartridges. When filtering dust that doesn’t easily release from the filter media, cartridges often plug and restrict airflow. Soon several customers and operators of these smaller dust collectors found themselves dealing with filter issues and contacted Parker Hannifin for a solution.
Our engineering team used advanced engineering tools, Computational Fluid Dynamic modeling, and 3D printing to design a filter cartridge that can handle more demanding conditions. Innovations like our louvered grid on top of the filter not only more evenly distribute the cleaning air but also serves as a handle for cartridge removal and ASHRAE 199 testing validated the new design. After extensive analysis, laboratory, and beta-site testing, some of the first BHA TotalPleat cartridges were installed in September of 2019 in a collector in the southeast United States. The collector, on top of a cement loadout silo, is in plain view of the adjacent interstate and visible dust emissions would attract immediate attention.
With the new TotalPleat cartridges, a remote monitoring device was installed to track the collector’s performance. As of December 2020, there had never been any visible emissions from the TotalPleat filters and differential pressure has been excellent (see chart on page 2 for the dp trend). A year-plus after installation and without any maintenance, TotalPleats are still running strong while the original OEM cartridges had emission and pressure drop problems within the first three months of operation.
What is noteworthy is that during the first days of operation, the TotalPleat filters were slightly damaged because the header pressure for the pulse valves was accidentally set to 100 PSIG instead of 60 PSIG. This has not caused any operational issues or emissions and speaks well for the robust new design.
