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:
50 to 300 mm) and water-cooled types (discharge bore diameter: 80 to 350 mm) as standard
models. Whether used under low pressure (0.6 kg/cm2 or less) or high pressure (0.6 to 0.8
kg/cm2), the appropriate model can be selected according to application.
Use at 0.8 kg/cm2 or higher pressure is available as a special specification. In addition, blowers
can be equipped with a helical rotor (discharge bore diameter: 80 to 250 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.

How To Select The Blower Model

The Selection Chart indicates the relationships between blower model, 3. To convert amounts of air under discharge conditions to amounts
bores, revolutions, discharge pressures, actual air flow rates, and the  of air under standard suction conditions indicated on the Selection
shaft powers.  Chart, use the following formula:
      101.3 + Pd 273 + t s
1. The amount of air indicated in the Selection Chart represents the  Qs = Qd × ————— × ————
 suction amount under the following standard conditions:         101.3 273 + t d
 temperature 20°C, absolute pressure 101.3kPa, and relative  Qd, amount of air (m3/min.) under discharge conditions;
 humidity 70%.  Pd, discharge pressure (kPa)
2. The amount of air under reference conditions (0°C, absolute  Ts, suction temperature in °C
 pressure 101.3kPa, dry) can be converted to amounts of air under  Td, discharge temperature in °C
 standard suction conditions by the formula below if the suction 4. Using the amount of air and the necessary discharge pressure
 pressures are the same:  obtained from the above calculations, determine your blower
 model, bore, revolution, and shaft power referring to the Selection
      273 +ts
 Qs = Qn × ————  Chart.
       273 5. Your selectable range can overlap several models. It is
 where  recommended that one with a smaller model number be selected
 Qs, amount of air (m3/min) under standard suction conditions  for cost economy, or one with a larger model number be selected
 indicated on the Selection Chart;  for lower noise.
 Qn, amount of air (m3/min) under reference suction conditions; 6. For necessary motor output, refer to required power (La) in the
