### ⭐⭐⭐⭐⭐ WORKS GREAT / MOVES A LOT OF AIR.
*by K***S on April 11, 2025*

WORKS GREAT / MOVES A LOT OF AIR.

### ⭐⭐⭐⭐⭐ Using as an inline duct fan, incredible airflow, easy to install, well-built
*by L***D on January 9, 2013*

I am using the Rule 240 blower as an inline booster fan for our restroom's exhaust fan. I installed it in the attic, suspended using straps and the support from the ducting. The reason I did that was to isolate the vibration of the blower from the struts. If I directly attached it, the vibration is enough to create a humming noise throughout the whole house. With the straps, the fan is not audible.That noise, now isolated, is actually a testament to the amount of air that is moved through this fan. I use the 12v 6a Adapter Power Supply for LCD Monitor with Power Cord as the power supply to power it, and it has been working great so far. The blower is switched by the same wall switch hooked up to the exhaust fan. Using this power supply, since it is a switched mode one, there is a small delay in turning on the blower; and that's when things get interesting.As we flipped the switch, the exhaust fan turned on right away and would have the same noise as it did before (it's a low-cost Broan). But as soon as the blower fan started, we could hear a "swish", and the Broan fan is now almost quiet, leaving the blower fan doing all the work. As an engineer, this is easy to understand, since the blower fan has created a very low pressure zone for the Broan exhaust fan, so it is under very little stress. The rated spec of the blower gives about 3 times the airflow of the Broan exhaust fan, and the result is consistent with that.I tested the air flow from under the closed bathroom door as well, to see what the air flow rate has changed. With the blower fan, it almost feels like there is a gush of air coming in from outside the bathroom. The best part was the "hot shower test". In the past, with only the Broan exhaust fan running, there would still be a lingering mist in the bathroom after a 5-minute (we are green) shower. Now? Nothing. No fogging in the mirror, and if I observed it during the shower, I could see the mist being sucked up at a really high rate. Given that this is a bilge pump, I also have a lot of confidence that the moisture is not going to change its reliability, and it's perfect for the purpose.Overall, I am extremely happy with the purchase. It solves the air circulation and ventilation problem in our upstairs bathroom AND corridor (yes, it sucks that much air). I recommend it.

### ⭐⭐⭐⭐⭐ Awesome bilge blower, works great.
*by T***H on March 29, 2014*

This marine bilge blower works great. I installed this in my boat last season without a hitch, and it has worked as expected since. The unit is pretty quiet while operating, I sometimes have to verify that it is working by opening the bilge hatch.The installation of this bilge blower was simple. All you have to do is connect a positive 12v DC source (mine is on a switch) to the red wire, and then connect the black wire to the battery's negative terminal, or another ground source. Then you can run ducting from the unit to a vent, to rid your bilge of gas fumes. In my case, I already had an intake and exhaust cowl for venting the bilge on my boat, but the bilge only vented properly while the boat was underway. I just positioned this blower near the exhaust cowl on my boat..The unit is constructed of a standard plastic material. It seems to be well made, and under normal conditions, I'm sure it will hold up just fine.If you find a use for this unit inside of your home (as some reviewers have), you will also need an "AC to DC power converter," which you can find here on Amazon.Hope this helps.
