V-pleat filters for general ventilation system stainless steel activated carbon filters, a filter area, low air resistance activated carbon filters, long service life. It can be used as high efficiency filter pre-filter to use, so as to effectively extend the service life of high efficiency filter. V-BED-type filter V-BED type of middle and high efficiency filter duct activated carbon filters, this product is designed to achieve the amount of demand at low wind resistance design and development. LV Series high efficiency wind speed reaches 2. 5m / s in the case of the initial resistance of 250Pa (ie 500 games m). The air filter is a baffle member of Key trap efficiency. Baffle vanes provided in the baffle timing Note 4:01) size appropriate angle: angle is too large, the cyclone airflow is not obvious, watershed ineffective; angle is too small, the separated water will run up, it is hard to the bottom cup. Blades 30 ° ~ 45 ° is appropriate. 2) the blades have sufficient strength, while there is sufficient flow area. 3) deflector installed activated carbon filters must be solid and reliable, because the airflow through the deflector blade has a larger reaction, easy to make baffles loose or failure. 4) rotation. Many manufacturers are using left-handed, but after testing, left and right hand, and no significant difference.
