What filtration efficiency does it provide?
The filter is available in various grades (G4, F5, F7, F9) corresponding to EN 779 or similar standards. The exact efficiency depends on the micron rating you choose. -
Is the filter washable or replaceable?
Polyester media can be cleaned by compressed air or gentle washing in some applications, but we recommend replacement after reaching its dust holding capacity for optimal performance. -
