For static pressure dial code, please see the following Table:
ENC2
Low static pressure
Model
18~71 0~15Pa
1.The noise is higher when ENC2 is
than that when it is
2.In the curve diagram for static pressure air flow volume, 2H means ENC2 is
speed. 2M means ENC2 is
low speed.
1H,1M,1L indicate the testing diagram of the fan in high, medium and low speed when ENC2 is
0H,0M,0L indicate the testing diagram of the fan in high, medium and low speed when ENC2 is
