SIHAO 3-Stage Laser Smoke Purifier with Activated Carbon + HEPA + Pre-Filter – Fits CO2 Engravers 50W To 150W, Removes Odors & Particulates

Sihao Fumes Extractor for laser fume/smell disposal, used for laser machine processing material like PVC/PET/Acrylic/plastic/ paper/metal/lether, our fume extractor included prefilter, HEPA filter and activated carbon air filter  

1. Strict welding and painting technology achieve to high tightness and corrosion resistance cabinet.  

2. Specific sound-absorbing materials reduce operating noise to improve operation efficiency.  

3. This fume extractor use China blower, high pressure, low noise. It can effectively absorb particle and extend filter life of less power.  

4. VEVOR filtration system consist of four parts, they are metal filter, F5 class pre-filter, HEPA main filter and gas filter.  

(a). Well-proportioned holes to ensure that large dust particles are trapped on the metal filter, to prevent them block the pre-filter.  

(b). F5 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.  

(c). 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.  

(d). Gas filter layer formed by the chemical materials can effectively remove harmful gases and pungent odor in the air.

The first layer is a medium-efficiency bag filter (aluminum alloy frame, filter material is high-quality chemical fiber filter material, 4 bags; filtration efficiency is F7 (colorimetric efficiency 85%).)

The second layer is granular activated carbon (cylindrical)

The third layer is activated carbon filter (paper frame, honeycomb activated carbon particles.)

The fourth layer is filter cotton (30mm thick white primary effect fluffy cotton, the filtration efficiency is G2.)

The fifth layer is a high-efficiency filter without separators (aluminum alloy frame, glass fiber filter material, filtration efficiency H13 (corresponding to the traditional 0.3μm particle sodium flame method with high efficiency, double-sided sealing strips, double-sided protective net.)
