Experience the UAS Filter Standard: ProTura® Nanofiber
Keep your cartridge dust collectors running efficiently and energy smart with high-quality cartridge filters from United Air Specialists. Available in an assortment of media - including our proprietary ProTura Nanofiber- our cartridge filters rank among the highest in performance, efficiency and value.
Rated at MERV 15, replacement cartridge dust collector filters with our ProTura Advanced Nanofiber technology are up to 95% efficient on 0.3 to 1.0 micron size dust. These filters have a surface treatment of the finest synthetic nanofibers used in any current filtration product . Exceptionally small in size, these fibers are about 50% finer than the “other” nanofiber filtration technology, are more durable, with better moisture and temperature resistance and stronger adhesion to the media substrate.
Independently proven to achieve higher initial efficiency, cleaner air, lower pressure drop and greater energy savings than commodity filter media, our proprietary ProTura Nanofiber is the standard technology that we equip all of our cartridge dust collectors with. However, you can also choose from poly-glass and 100% spunbond polyester to meet all of your replacement filter needs. See the chart below for available replacement filter options from UAS.
Surface Loading Technology
The Value is the nanofiber-not the substrate
ProTura nanofiber acts as a shield to prevent submicron particles from entering and becoming embeded within the filter's substrate media. As a resulet, pressure does not build up as rapidly and power requirements are dramatically redced.
Ordinary nanofiber filters require the use of synthetic materials to attain the efficiency level of ProTura nanofiber filters. These materials make the filter more expensive and more restrictive to airflow, leading to an increase in pressure. Ordinary nanofiber cartridge filters may achieve the same MERV rating as ProTura filters, but they provide far less media( more than 50% less), reduced air flow capacity, shorter filter life and a premium price tag.

Filter Media And Applications:
| Filter Media | Unique Characterstics | Typical Applications |
| ProTura Nanofiber | Suitable for most applications. This is the standard filter that is icluded in all base units. Maximum Temperature: 180° F Washable: No |
|
ProTura Nanofiber Fire Retardant | For applications where live sparks could enter the dust collector. Will not suppress fires if collected materials are combustible. Maximum Temperature: 180° F Washable: No |
|
ProTura Nanofiber Wide Pleat | For applications where large or irregularly shaped particles may enter the dust collector. Maximum Temperature: 180° F Washable: No |
|
ProTura Nanofiber Fire Retardant Wide Pleat
| For applications where larger particles and live sparks may enter the dust collector. Maximum Temperature: 180° F Washable: No | Coarse grinding of ferrous metals |
| Poly-Glass | For applications with larger particles or with hygroscopic or agglomerative dusts. Filters can be washed and reused. Maximum Temperature: 180° F (High temperature version to 275° F is available) Washable: Yes |
|
100% Spunbond Polyester | For applications where high-strength media and excellent release characteristics are necessary.
|
|
100% Spunbond Polyester with PTFE Membrane | For applications demanding ultra-high filtration efficiencies or difficult dust cake release requirements. Spunbond PTFE filter cartridges use a PFTE membrane to repel moisture while allowing air and moisture vapor to pass through the membrane's extremely small spaces. Maximum Temperature: 180° F (High temperature version to 275° F is available) Washable: Yes |
