Soler & Palau S&P PV-100XPS Powervent Clothes Dryer Exhaust Booster Kit with Pressure Sensor

I originally purchased this PV-100XPS dryer booster fan (returned box) on Amazon.com in 2019 (Total dryer vent hose length is about 25 ft). It functioned flawlessly for 6 months, then the fan blades exploded. There were warranty issues, and it took a while to get Amazon to own up to a replacement. We replaced it with a new one in 2019, and it's been running strong for 5 years. It automatically turns on when the dryer starts, and shuts off a few minutes after the dryer cycle ends. If you've got issues with clothes not drying or lint buildup in your vent lines due to a longer-than-normal dryer vent line, I highly recommend this product (if you buy it new). Note: For this item, don't buy returns through Amazon, because even though the listing might say it's still covered by the manufacturer warranty, it wasn't in our case.

Really great item. It is large and will take up most of the space between the two floor joists if you install it in the celling. The operation is very quet and fan is nicely balanced. It is not silent but it is bearly notisable when running. Remember that it is basically mandatory to add a secondary lint trap otherwise it will get covered in lint and can cause issues. The only minor complaint is that input and output duct connectors are a little smaller then standard 4inch duct, so ducts fit loose and clamping is impossible. You will need to use aluminum tape to hold the lines on.

I've purchased and installed two of these units (new). The second one just died, (fan bearings failing, causing loud rattling, grinding noises). It was in service for just shy of 4 years. The previous unit died after just over 4 years. I do appreciate consistent engineering! But think I'll try another brand, to see if it lasts longer, especially at $300 for a third replacement. All that said, while in service, both units worked well. Kept the dryer air exhaust airflow strong. Sometimes the unit would stay on long after the dryer had shut off, but this happened rarely (far as I know). But a quicker shut down in general would probably lengthen the lifespan of these booster fans.

Cheep house contractors of the day decided to run the dryer duct up the wall and out the roof. After a couple of years the dryer takes forever to dry your stuff. Dryers don't have enough fan power to pump the hot air and lint up and out two stories high. Go up to the attic, cut the duct and install this. Problem fixed. (After you spend all day cleaning years of lint out of your dryer ducts and wondering how you managed not to catch your home on fire)****** BEWARE OF THIS UNIT******* I have now had to pay for and install 2 of these units in the last 3 years. Both units have failed in the same place. The fan blades come lose from the drive plate and make the whole unit vibrate and make noise. Going with a different brand this time........

Excellent and quiet product. But, be prepared for difficulties installing fan. If you have available power and a convenient location with an adequate surface to mount fan, it would be simple. In my situation, I had numerous obstacles that made my installation difficult. Bottomline: This fan solved our problem.

Worked great for about 8 months and now it sounds like it is trying to rattle apart.

I NEVER knew I had a dryer booster fan until it went bad. I have only lived in my current house for three years. The dryer started making a strange noise, but when the dryer turned off, the noise continued. I went up into the attic and saw the booster fan attached to the ductwork. Well there’s my problem! Fortunately Amazon had the exact unit I needed. Took maybe an hour to replace. Some other reviews mentioned that they could not get 4” hose clamps to work on the flanges. The old one did not have any, but I figured I would try. Sure enough the flanges seemed to be sufficient tightened down the insulated flex duct to the flanges. I still use some ductwork tape around the connection, just to allow for additional sealing.

Bought a new home - this model was under the home because the dryer is physically at the front of the home and the dryer vent is in the back. After 4 years of use, the old unit began making a noise like a bearing going out or a blade working loose. (helicopter under the house). The new unit was cost-effective, and an easy replacement since it was the same size. If this one breaks after 4 years, I'm getting a different model. Hope this helps!
