@cgi You mention that HP220 is a bit more powerful than needed so you use a timer to turn the fan on and off. I'm thinking to install a speed controller to adjust the speed of the fan thus adjust its suction power. Have you ever considered this option? What do you think?

Looks like Fantech has fan speed controller but I'm not sure it can be used for radon gas exhaust fan. I've send an email to http://www.radondetect.ca/Fantech-HP220.html asking if they have such controller. I'll report once I have reply from them.

This link from US is selling Fantech controller.

Here is a short reply I got from www.radondetect.ca

"You can install a fan speed controller but not a light dimmer. The proper one would be the same as used on a ceiling fan."

So basically a ceiling fan speed controller will work with Fantech radon fan.

看样子不错。但是我没有使用这种东西的经验，所以现在是在研究中。

 

[uglyducking]

为什么要整这个幺蛾子呢？嫌氡气拍的太快？

 

[Fetion]

吸力太大了室内会形成负压。

 

[Fetion]

个人观点，装这个东西一个难点是选适当吸力的泵。

 

[Fetion]

所以想法是装个稍大的泵，但可以调节吸力，而且可以根据季节不同来调节。

@cgi, I got another response from hvacquick, FYI ...

Your Question: Hi,I have a question for the Fantech Speed and Fan Controller. Can it be used to control Radon Gas fan? If so, which one can be used to control Fantech Radon Gas fan, for example, HP220?Thanks,Andy

Answer: You can use the WC15 speed controller. Typically we do not see speed controls used on radon fans as you want the max pressure the fan can generate to ensure the radon is exhausted. Better to size the fan correctly -- more energy efficient as well. Thanks.

可以，我这儿有5个没买到的，加上你就6个人了。我发现寄到Ontario还能省5块税钱。
