UAS NanoFiber Cartridge Filter

The United Air Specialists Advanced NanoFiber cartridge filter provides superior filtration efficiencies (MERV 15), long filter life, and reduces compressed air usage. The NanoFiber surface layer creates a true surface (not depth) loading cartridge filter that pulse cleans more efficiently than depth loading filters, resulting in lower pressure drop that ultimately reduces the amount of pulse cleaning required.

The UAS NanoFiber cartridge filter can be used in most cartridge-type dust collection systems, including:

  • Torit
  • Farr
  • AAF
  • Micro-Air
  • Most other brands
