The Pre-Filter for the BOFA Print PRO 2 or 3 Fume Extraction System is designed as a barrier to capture dust and larger particulates before the combined HEPA/Carbon filter cleans and cleanses the air of any fumes produced by the 3D printing process. This is an F8 rated filter, with 95% efficiency at 0.9 microns. It is recommended you replace the Pre-Filter in your BOFA Print PRO 2 or 3 Fume Extraction System every 12 to 18 months.
The BOFA 3D PrintPRO 2 & 3 Fume Extraction System can sit on your desktop, workbench, or on the floor with the Stay Put Arm and funnel positioned next to your 3D printer’s build area. It pulls a small amount of air and any fumes that would come from heated filament extrusion and filters it through a three-stage filtration process. First, the surface area of the pre-filter captures any large particles before the webbed mini-pleat HEPA filter grabs any small particles that may have escaped the pre-filter. Finally, the optimized advanced carbon filter absorbs and eliminates any fumes that remain before venting out nice, clean air. BOFA has made it simple for users, and each filter stage features a condition indicator, so that you know when it is time to replace the filter.
