www.tsurumi-global.com RSR-KS ROTARY AIR BLOWERS
Rotary Air Blowers Tsurumi's RSR-KS series rotary air blowers are equipped with a 3-lobe spur rotor. This rotor, as the most important component of a blower, is designed for corrosion resistance, heat resistance and durability, in addition to low noise, low vibration, ease of maintenance and high efficiency, thus providing stable performance, and ensuring smooth operation of the blower over a long period of time. The product lineup of the RSR-KS series comprises air-cooled types (discharge bore diameter: to mm) and water-cooled types (discharge bore diameter: to 3 mm) as standard models. Whether used under low pressure (0. kg/cm 2 or less) or high pressure (0. to 0. kg/cm 2 ), the appropriate model can be selected according to application. Use at 0. kg/cm 2 or higher pressure is available as a special specification. In addition, blowers can be equipped with a helical rotor (discharge bore diameter: to mm). The RSR-KS series is suited for various applications, such as for aeration at wastewater treatment facilities, agitation of wastewater and sewage, decomposition and scum prevention, and oxygen supply at fish farms. Tsurumi also offers other water treatment equipment besides blowers, including submersible pumps, aerators, mixers, scum skimmers, bar screens and dehydrators. These products have been tested and proven for many years in the field of water treatment, and can be supplied as a total package. 1 2
Blower with 3-lobe Spur Rotor Rotor The 3-lobe spur rotor is designed for corrosion resistance, heat resistance and durability, in addition to low noise, low vibration and high efficiency operation. Fluid is drawn from the inlet on the upper stage and discharged from the side on the lower stage. This structure reduces noise and provides higher efficiency. Installation Diagram Discharge Silencer Belt Cover Blower Suction Silencer Motor Side Cover The side cover supports the bearing and is structured to allow compressed air that has leaked via the shaft to flow out of the casing, without intrusion into other components. With water-cooled type blowers, cooling water is supplied to protect the bearing against temperature rise during operation at high pressure. Shaft The shaft is made of carbon steel for mechanical structure, which has undergone precision machining for shrink-fitting in the rotor. Timing gear The timing gear is made of chromium molybdenum steel. A Class 1 spur or helical gear is used to ensure stable power transmission, resulting in friction noise reduction.

The amount of air indicated in the Selection Chart represents the suction amount under the following standard conditions: temperature C, absolute pressure 1.3kPa, and relative humidity 0%. The amount of air under reference conditions (0 C, absolute pressure 1.3kPa, dry) can be converted to amounts of air under standard suction conditions by the formula below if the suction pressures are the same: 23 + t s Qs = Qn 23 where Qs, amount of air (m 3 /min) under standard suction conditions indicated on the Selection Chart; Qn, amount of air (m 3 /min) under reference suction conditions; Suction pressure is ambient pressure, 1.3kPa; t s, suction temperature in C Rotor S: Spur (standard) H: Helical (option) Name of the series To convert amounts of air under discharge conditions to amounts of air under standard suction conditions indicated on the Selection Chart, use the following formula: 1.3 + Pd 23 + t s Qs = Qd 1.3 23 + t d Qd, amount of air (m 3 /min.) under discharge conditions; Pd, discharge pressure (kpa) Ts, suction temperature in C Td, discharge temperature in C Using the amount of air and the necessary discharge pressure obtained from the above calculations, determine your blower model, bore, revolution, and shaft power referring to the Selection Chart. Your selectable range can overlap several models. It is recommended that one with a smaller model number be selected for cost economy, or one with a larger model number be selected for lower noise. For necessary motor output, refer to required power (La) in the Selection Chart.
