I. Introduction Product rainwater gravity flow characteristics of the rain in the garbage and water automatically separated, resulting in cleaner rainwater. After rain water inside the device changes elbow flow, the flow in the vertical direction, encounters the shunt umbrella structure, so that rainwater flows along the edge of the umbrella contact vertically positioned filter, the flow of rain water through the filter after the filter chamber, the garbage along net surface down to the trash receiving opening, so rainwater is filtered, rubbish split and automatic discharge. Rainwater automatic filter high precision, net diameter to 0.4mm, usually installed in the interception, after abandoning flow filtration, filtration is complete rainwater can be directly poured green, very effective. Sewer filter penetration properties can be made without direct docking with the outfall. II. Product Specifications Model YBSRF-200 YBSRF-300 YBSRF-500 device size height 1000mm, 500mm diameter height 1000mm, 500mm diameter height 1000mm, 700mm diameter port size DN200 DN300 DN500 Material PE / Stainless steel 302 PE / stainless steel 303 PE / stainless steel 304 three Product applications is a patented filter rainwater, usually installed in the pre-filter rainwater collected link, you can filter the roof, ground rainwater, rain water entering the reservoir cleaner. IV. Features 1, filtered rainwater gravity sewerage automatic operation, rain and dirt separated automatically, with no loss of rain, dirt automatically separated under gravity and erosion effect. 2, with a 0.4mm stainless steel filter, after filtration is complete, it can directly poured green. 3, long maintenance cycle, generally only six months or a year or so apart to clean once. 4, inner material made of high quality stainless steel, longer life. 5, PE finished well, with a heightening accessories that can be directly buried, installation is simple, convenient and suitable to the riser, install the underground pipe rollup.
