Description of Performance parameters
The performance parameters table exhibits the design, outlet diameter, rotate velocity, discharge pressure, air capability and power of motor.
one. The air capacity and strain in the tables is in normal suction condition. The normal suction condition is 20ºC temperature, one.033 kgf/cm2(a hundred and one.3Kpa) Common atmospheric strain and 65% relative humidity.
two. The air capability and strain assortment of some blower versions is repeated, to make sure the support existence and low sounds, should use the greater design.
