noisy 43502 aspiration shield

Geert Jun 16, 2011 05:39 PM

Hello,

Today i installed the new Young 43502 radiation shield.
But the fan inside the shield make a lot of noise (like a vacuum cleaner). When i use another power supply (5 volt) the noise is acceptable.

Is this normal?

regards

Geert

The fan in the 43502 is very powerful, perhaps too powerful.
However, if you use a lower voltage though you will likely compromise the performance as the lower the windspeed the larger the error from solar warming of the shield.

When i put 5V on the blower the noise is acceptable.
I give it a try.
