Nanotechnology and Respirator Mask


One example of nanotechnology is the use of nanofibers as a performance layer for industrial air filtration applications. To produce a nanofiber layer, an elect­ro-spinning process creates a very fine, continuous, resilient fibre of 0.2 – 0.3 micron in diameter that is then applied to a filtration media substrate material. The nanofibers form a permanent web with very fine interstitial spaces on the surface of the substrate. The web collects dust, dirt and contaminants on the surface of the filter; this offers many benefits over conventional filters built with cellulose, cellulose/synthetic, spun bond, or melt blown commodity filtration media.




Multilayer nanofiber face mask


Although the cost to purchase premium nanofiber performance layer filters for a dust collector can be higher than commodity media filters, a strong argument can be made that the nanofiber layer filters are well-worth the higher buying price. Following are the top 5 reasons a premium nanofiber performance layer filter is worth it:


1. Higher initial and ongoing efficiency.

2. Lower pressure drop across the filtration media saves energy.

With a nanofiber performance layer filter, the collected dust accumulates on the surface of the filtration media rather than within the media and is cleaned off with fewer pulses. Fewer pulses results in fewer potential emission-producing events.




3. Longer filter life

Most dust collector filters reach an end of life when the filtration media is fully depth-loaded and can no longer be cleaned to an acceptable degree to allow design airflow with the available fan in the system. Because of the nanofiber efficiency layer and surface loading characteristics, nanofiber layer filters last significantly longer than traditional commodity filter elements. Longer filter life means buying new filters less frequently, saving considerable money over time. Additionally, longer filter life reduces the frequency of costly operation downtime for filter change maintenance activities.
