Laser fume extrator PA-500FS/FD

PA-500FS/PA-500FD filtration system consist of four parts, they are metal filter, F8 class pre-filter, HEPA main filter and gas filter. Well-proportioned holes to ensure that large dust particles are trapped on the metal filter, to prevent them block the pre-filter. F8 class pre-filter comprised by cotton and metal mesh, full-thickness adhesive, can be adsorbed middling particles in the air to avoid main filter is blocked. Main filter consists of efficient HEPA element, in independent tests, these filters remove 99.997% of all particles above 0.3 microns and 95% down to 0.01 micron. Gas filter layer formed by the chemical materials can effectively remove harmful gases and pungent odor in the air.
