The booths of many brands are only equipped with single-layer activated carbon filter, which can only filter the peculiar smell, and basically has no filtering effect on the overspray. Overspray cannot be directly discharged into the air, which will cause air pollution and even complaints from neighbors. When the overspray is discharged indoors, it will adhere to all indoor items and is difficult to clean.
The filtration efficiency of the booth depends on the power and flow of the blower. When the blower inflates, the air pressure inside the booth is higher than that outside, forming a continuous exchange of air. Simply increasing the number of filters without increasing the blower will not improve the filtration speed. This will only reduce the air pressure inside the booth and prolong the residence time of overspray inside. When replacing the filter, it will cause huge economic costs and difficulties, and waste you more money.
Sewinfla booth adopts a more scientific design, and the fresh air is poured into the booth through an independent air inlet basket pipe. Maintain a reasonable air pressure difference between the inside and outside of the booth, realize rapid air exchange, improve the filtration efficiency, and save the cost of replacing the filter.
Booths of other brands do not provide suction devices for indoor use. Overspray is directly discharged indoors, causing serious air pollution and will be attached to various indoor items. In addition, the overspray will enter the booth again through the blower, making the filtering system of the booth completely ineffective.
