General Filter launches a line of filter pockets in synthetic nano fibers that substantially improve the technical performance of the classic fiberglass products.
In recent years the development of nanotechnology has achieved remarkable results in many industrial applications, such as the chemical, pharmaceutical, electronics, medicine, construction, sport sectors, and they are now also used to enhance the performance of synthetic filters.
Obtaining satisfactory results
The amazing properties of ‘nano fibers’ are essentially due to the minute size of their particles. In fact, when working on nano-sized, all those forces that are normally neglected, as the Wander-Wals one, begin to have a significant weight as the properties of these materials come just from the synergistic union of all these small forces.
It the field of air filtration we can also obtained very satisfactory results. They have compared glassfiber filter pockets sized 592 x 592 x 636 mm with 10 holes each for the filtering classes F7 and F9 made with nano fibers ones of the same kind.

| Glassfiber | Nano fiber | ||
| Efficiency Class | F7 | F9 | F7 | F9 |
| ΔP initial (Pa) | 82 | 161 | 61 | 122 |
| Dust Holding (g) | 445 | 339 | 545 | 521 |
| Energy Consumption (kWh) | 1000 | 2000 | 800 | 1600 |
From the table above, it is evident that the pockets made in nano fiber offer superior performance compared to the fiberglass ones both in terms of dust holding and energy consumption (Eurovent 4/21).
Considerable saving on consumption
This means that, at constant efficiency, the fiberglass is in energy class B, while the nano fiber is in class A with a considerable saving on consumption. The dust holding capacity, much higher, will also results in less maintenance, reducing costs of both material and personnel.
Moreover, the nano synthetic fibers are not detachable and therefore operators will not risk to breath them, a serious problem that might occur with glass fiber, a potentially carcinogenic substance.
