Esco Nanocarb™ Activated Carbon Filters
are constructed in order to ensure maximum filter efficiency, retention capacity and operator protection. Esco's research scientists and engineers, working in consultation with world-leading authorities on adsorption science, have developed the following set of unique technologies:
- Optimized retention capacity (i.e. the total weight of chemicals the filter can retain, usually as a percentage of its own weight) considering that activated carbon may have an increased adsorption capacity by weight, yet poorer overall filtration performance for the actual application. By considering the Isotherms of various activated carbon materials, Esco scientists have selected the optimum grade(s) of raw materials in order to achieve the best balance of all performance factors.
- Continuous incoming quality control tests on all activated carbon raw material procured.
- Generously sized filters with more activated carbon by weight retain more chemicals and last longer.
- Proprietary computer modelling software to predict application suitability, filter saturation capacity, and efficiency for single and multiple compounds.
- Rigid, sheet metal construction coupled with a flat-packed bed to minimize dusting and ensure even air-flow through the filter.
- Quick-changeout filter clamping mechanism allows filter replacements to be carried out with minimal tools; even filter clamping (perimeter, not point force) prevents leaks from occurring.
- Diffusion technology (US patent pending) to ensure even filter loading.
- Optional sensing technology (US patent pending) is available as an aid to predict filter breakthrough and warn the user to change the filters.
- Filters are individually installed onto each fume hood and certified at the factory before shipment.
