2. Noise Level
Through curve 2 and table 1, regardless of pressure points and just considering the Maximum Noise Level for W6E630NT0101 and S6E630AN0101 we can read 77 dB and 70 dB respectively.
It means:
All in all, for any fan’s selection the operating point and the condition of mounting should be taken into consideration.
3. 3% less energy consumption
Through curve 1:
HyBlade consumption: 560 W
AxiBlade consumption: 485 W
(AxiBlade consumes up to 13.3% less energy)
It means:
less cost for providing electronic parts such as VSD and less energy cost.
4. Volume rate change
Through the curve 4:
HyBlade volume rate: 7700 m3/h
AxiBlade volume rate: 7900 m3/h
The difference is 2.6%
Comparing the 4 above facts:
- Any low powered motor doesn’t imply a weakness in a system.
- An engineering design tends to gain a low energy consumption at an operating point
It can be seen that manufacturers don’t work on maximum air flow as a separate parameter, just do at an optimum point; more familiar metrics such as efficiency, power and noise.
5. IP , degree of protection
6. Environmental protection class is H2 for both models
H2 testing goes far beyond the requirements of the IP protection classes.
ebm-papst has taken the environmental conditions of an operating fan into account early on, as your requirements are more than IP classes (to find out more read the “Environmental Protection classes” handout).
