Product Name: Waste Water Treatment SSR Tri-Lobe Rotary Type Blower Model NO.: SSR Certification: ISO, SGS Pressure: Medium Pressure Flow Direction: L Usage: Waste Water Material: Iron Blower: Roots Blower Pump: Vaccum Pump Lobe: Three Lobes for: Waste Water Treatment Trademark: SSR Transport Package: Export Wooden Case Specification: JB/T8941-1999 Origin: Shandong Zhangqiu Blower Co. Ltd HS Code: 84145990 Product Description SSR Tri-Lobe Roots BlowerJapanese TechnologySSRBore 50~200Suction-phase Air Volume(m3/min) 0.78~60Discharge Pressure(kPa) 9.8~58.8SSR-VBore 50~200Suction-phase Air Volume(m3/min) 0.86~58.65Discharge Pressure(kPa) 0~-39.2SSR-HBBore 50~250Suction-phase Air Volume(m3/min) 1.24~90Discharge Pressure(kPa) 9.8~78.4SSR-VHBBore 50~250Suction-phase Air Volume(m3/min) 0.86~87.3Discharge Pressure(kPa) 0~-44Type: Three-lobe, low noise level, helical roots type.Usage: Sewage treatment, pneumatec system, vacuum application, aquatic farming etc.Features:1.The helical construction uses the stator helical method that the screen lines of casing at the suction and discharge sides are cut to a helical shape,and the triangle suction and discharge port formed by a straight line of the rotor top is to be opened and closed gradually.2.The rotors are three lobes.3.By adoption of an unique profile of rotor, the clearance between the rotors can be held to be constant, which makes the efficiency even higher.4.The precision of rotors is fully controlled and variation of precision between blowers is almost nil because the rotors are produced under the mass production control by utilizing a prenision NC maching.5.The advanced driving gears are adopted but only to extend the use life but also to make noise lower.6.The transported air is clean and is any oil-dust free oil lubrication is not needed in casing and the structure design prerent the bearing oil and gear oil from entering the casing.
