3 PERFOMANCE SELEDTION

The performance parameters shown in the tables are the air properties under standard atmospheric conditions ( i. e. the atmospheric pressure 101325 Pa; temperature 20 centigrade; relative humidity 50% and the air specific  gravity  1.2

In case the actual air conditions and the rotating speed differ from those shown in the tables, the performance of the ventilator can be

converted according to the following formulas:

Q=Q₀·                 ( m³/h )

P=P₀·( )²·          ( Pa )

N=N₀·( )³·          ( KW )

Among which

Q₀ ,P₀ ,N₀, are the volume of flow, pressure, power, and the specific gravity under standard air conditions and rotating speed.

Q,P,N,ρ,n indicate the actual volume of flow, pressure, power and air specific gravity and rotating speed.

Remarks:

1.The allowable error of the full pressure value under standard volume is -5%~+10%.

2. The limit values of noise of the ventilator is

LA≤26+10 lgP²Q

where P-mmH₂O

       Q-m³/min

The ventilator can be matched with marine AC motor of 380V, 50HZ or 440V, 60HZ types.
