Operating Principle and Application The aspirated gas flows through the compression chamber along a helical trajectory and is repeatedly accelerated by the centrifugal thrust of the impeller. Consequently, higher pressure will be obtained at the discharge slot. The impeller mounted directly on the motor shaft is rotating smoothly without friction and thus no lubrication is necessary. The pressure difference of course remains steady The Side Channel Blowers are widely used on: Pneumatic conveying systems, textile machines, printing machines, PCB process, dust collection, fish ponds, SPA, Dental suction devices, paper sorting and delivery, lifting and holding, packaging machines. Feature and Advantages Casing and impellers are made of aluminum alloy and have excellent features on mechanic strength durability light weight and smooth exterior. RB series Side Channel Blowers are designed to comply with the safety requirements of IEC/UL/CSA and have attained their type approval Meet CE Norm: 89/336, 73/23, EN60204-1, EN50081-2, EN50082-2 Degree of protection: IP54 Insulation class: F (1550C) Voltage Range: 1 Phase, 100~120 / 200~240 Volt 3 Phase, 200~240 / 380~440 Volt 3 Phase, 230~460 Volt Frequency: 50/60 Hz Installation: Any aspect   Brochure: Specification and Operation Diagram Dimensions
