HOW TO USE THE PERFORMANCE TABLE■Information about 50/60Hz Standard  Specification TablesThese tables indicate the relationships among blower models, bores, rpm, discharge pressure, actual air flow rates, and shaft power.1. The amounts of air indicated in the tables represent suction

amounts under the following standard suction conditions: temperature, 20℃; absolute pressure, 101.3kPa {1.033kgf / cm2}, relative humidity, 65%.

2. The amounts of air under reference suction conditions (temperature, 0℃; absolute pressure, 101.3kPa {1.033kgf / cm2})can be converted into the amounts of air under the standard suction conditions by the formula below if the suction pressures are the same: 

whereQs, amount of air (m3 / min) under standard suctionconditions indicated on Standard Specification Tables;Qn,amount of air (m3 / min) under reference suction conditions;Suction pressure is ambient pressure, 101.3kPa; ts, suction temperature in ℃.

3. To convert the amounts of air under discharge conditions into the amounts of air under the standard suction conditions indicated on the Standard Specification Tables, use the following formula:

  where  Qd, amount of air (m3 / min) under discharge conditions;  Pd, discharge pressure (kPa);  ts, suction temperature in ℃;  td, discharge temperature in ℃.4. Using the amount of air and the necessary discharge

pressure obatained from the above mathematics, determine your blower model, bore, rpm, and shaft power in reference to a Standard Specification Table.

5. Your selectable range can be overlapped over several models. It is recommended that the one with a younger model number for cost economy, or with a larger model number for lower noise, be selected.

6. Motor output is identified by color on the Standard Specification Tables. Select a suitable color motor from these tables.
