RadialSHIELD Air Filters for Heavy Equipment

RadialSHIELD Air Filters for Heavy Equipment

When it comes to filtration, we obsess over the smallest things – like microscopic dust, nanoparticles, and other contaminants. The new generation of RadialSHIELD® filters feature high-tech filtration media which arrests biological nanoparticles, including those the size of the COVID-19 virus, and other harmful contaminants frequently found on jobsites, such as diesel particulate matter (DPM) and respirable crystalline silica (RCS)

Description Substantially improves air quality on job sites. When standards compliance is not the primary objective, this filter is a high-performance, cost-effecive solution.

Along with excellent air quality, may provide extended filter life compared to HEPA.

ISO 23875-compliant filter, applicable to most job sites and high-debris appplications, is designed to arriest small airborne contaminants and meet timed dust decay rates.

Specialty filter designed to arrest the smallest airborne contaminants and respirable particulate, meant for specific conditions that require top-grade HEPA filtration.
