Bofa AD Nano pre-filter 1UA1030190


BOFA Pre-filters are designed to capture larger particles before they can enter the main HEPA filter. Without these pre-filters in place, the main filter life would be significantly shorter.

Key Features of the BOFA Pre-filter Pads:

The efficiency of the pre-filter is directly related to the life of the HEPA in that the more particulates captured in it, the less can pass through and prematurely block the HEPA. Most pre-filters have an efficiency grading of F5 ~F7. W

hen plastics are being lasered, the particulate size generated is typically 0.2microns. At this level of filtration, the media has an efficiency of 35% in F% to 65% in F7.

When metals are being lasered the particulate size being generated is typically below 1micron. This equates to an efficiency of 65% in F5 to 80% in F7.

The BOFA range of fume purification systems have an F8 grade media which gives an efficiency of 80-% at 0.2micron and 95% at 1micron.
