Revolutionary Hydro-Entangled Felt Filter Media Designed for Industry-Leading Dust Collection Perfomance
The Micronics Engineered Filtration Group is proud to supply new technology to the industrial dust collection market – Hydro-Maxx® – a Hydroentangled Felt filter media produced from a unique process technology that delivers superior filtration performance.
Historically, various fiber types have been formed into different weights of filter media through a traditional needle loom (needling). However, today’s utilities and industrial users are demanding higher-performance filtration, filters that deliver improved collection efficiency with lower operating costs. The Micronics Engineered Filtration Group is proudly meeting these needs with its hydroentangled felt offerings.
Hydro-Maxx® filter media – available only from the Micronics Engineered Filtration Group – combines the benefits of needle loom fiber entangling with revolutionary hydro-entangling technology to deliver industry-leading dust collection performance. The phenomenon of entangling fibers with high-pressure water jets creates a unique balance of lower mean pore size in a mass-efficient structure. Hydro-Maxx® represents a new paradigm in filtration media – it delivers a product with dramatically improved filtration efficiency, an inherent ability to promote surface dust collection, lower pressure drop over time, and reduction in pulse cycle times.
Available Fibers From Hydro-Maxx® Felt:
Polyester
PPS (RYTON®)
P84®
Homopolymer Acrylic
Aramid (Nomex)
Filtration Performance
Filtration performance characteristics are best demonstrated through the VDI test, a test apparatus specifically designed to characterize filter media performance in a baghouse application. Using the VDI test to compare a typical 16 oz/yd2 needlefelt from the market with a lighter weight 14 oz/yd2 Hydro-Maxx® filtration felt, the results show dramatic improvement in filtration performance as measured by clean gas concentration (mg/m3).
Fundamental gains in filtration efficiency are a direct result of fiber-entangling technology. The impact of hydro-entangling results in lower mean flow pore size and improved consistency versus a traditional needlefelt. The improved fiber entangling can be observed through a comparison of SEM images, as shown below.
Surface Dust Collection
Technically savvy end-users know that filter media that promote surface dust collection deliver improved baghouse performance by more effective cleaning from bag pulses. Additionally, in applications where gas stream reagents and sorbents are used, surface dust collection helps create a platform where the chemistry can be allowed to perform most effectively. The images below were taken after the execution of the VDI test, where standardized test dust becomes embedded in the needle felt, resisting the effect of the bag pulses.

Clean-ability
The Hydro-Maxx® filter media promotes surface dust collection in a way that responds more effectively to bag pulses, leaving the surface much cleaner and ready to perform during the next cycle. VDI data from a series of tests is characterized in the data shown below. When comparing pressure drop performance over time for membrane, needlefelt, and Hydro-Maxx® media, the Hydro-Maxx® media demonstrates improved ΔP over time delivering lower operating costs to users. Hydro-Maxx® is available in all fiber types commonly used in needlefelt including PPS, PET, and Aramid.
