1. The strict welding and painting processes ensure that the cabinet has extremely high sealing and corrosion resistance.
2. The use of sound-absorbing materials can effectively reduce operating noise, thereby improving the efficiency of the equipment.
3. This exhaust fan uses Chinese fans, operates at high pressure, and has low noise. It can effectively absorb particulate matter and extend the service life of the filter element.
4. The VEVOR filtration system consists of four parts: a metal filter, a F5-level pre-filter, a HEPA main filter, and a gas filter.
(A). It is designed with good proportion holes to ensure that large particles of dust are effectively intercepted by the metal filter screen, preventing them from blocking the pre-filter.
(B). The F5-level cotton metal pre-filter uses full thickness adhesive glue and can adsorb medium-sized particles in the air, effectively preventing them from entering the main filter.
(C) The main filter uses efficient HEPA components. After independent testing, it can effectively filter out particles ranging from 0.3 microns to 0.01 microns and above, with a filtration efficiency of 99.997%.
(D). The multi-layer gas filter is made of chemical materials and can effectively remove harmful gases and pungent odors from the air.
The first layer is a medium-efficiency bag filter (using an aluminum alloy frame, with high-quality chemical fiber filter material, 4 filter bags; filtration efficiency is F7 level, i.e., pore efficiency 85%).
The second layer is granular activated carbon (cylindrical).
The third layer is an activated carbon filter (paper frame, honeycomb-shaped activated carbon particles).
The fourth layer is filter cotton (30 millimeters thick, white, with primary filtering effect, fluffy cotton material, filtration efficiency is G2 level).
The fifth layer is a high-efficiency non-separator filter (using an aluminum alloy frame, glass fiber filter material, filtration efficiency reaches H13 level; in line with traditional 0.3 micron sodium flame standard, with high efficiency; equipped with double-sided sealing strips and double-sided protective nets).
