10002986 - Diversitech 26-Inch Nanofiber Replacement Cartridge for Fred Jr/Eco

High-Efficiency Filtration for Industrial Environments

The Diversitech 26-Inch Nanofiber Filter Cartridge (SKU: DIVINV-FILT-26NF) represents a premium solution for maintaining optimal air quality in industrial settings utilizing Diversitech's portable fume extraction systems. Specifically engineered for the Fred Jr. and Fred Eco series, this cartridge utilizes advanced nanofiber technology to deliver superior filtration performance compared to standard cellulose or polyester media. The core of this product's effectiveness lies in its ultra-fine nanofiber web, which is bonded to a sturdy substrate. This construction creates a microscopic mesh that captures sub-micron particles—such as hazardous welding fumes and thermal cutting smoke—on the surface of the filter rather than allowing them to penetrate deep into the media bed.

This surface-loading characteristic is critical for systems equipped with reverse-pulse cleaning mechanisms. Because the particulate matter remains on the exterior of the pleats, the compressed air pulse can easily dislodge the dust cake, restoring airflow and significantly extending the operational life of the filter. With a MERV 15 efficiency rating, this cartridge is capable of capturing 99.99% of particles ranging from 0.3 to 1.0 microns, making it an essential component for facilities aiming to meet OSHA standards and protect worker health against hexavalent chromium, manganese, and other weld fume constituents.

The cartridge features a 26-inch height and an Open/Closed (O/C) end cap configuration, ensuring a precise fit and seal within the extractor housing. This prevents air bypass and ensures that 100% of the airstream passes through the filtration media. The structural integrity of the cartridge is maintained by heavy-duty expanded metal liners and durable end caps, designed to withstand the pressure differentials and mechanical stress of continuous industrial operation. By choosing the Nanofiber option over standard media, facility managers can expect lower pressure drops, reduced energy consumption, and less frequent filter changes, ultimately lowering the total cost of ownership for their fume extraction equipment.
