6"/150MM Inline Mixed Flow Duct Fan
Very nice fan
I bought two and installed an air exchange system between my upstairs and downstairs to keep the temperature equal between the two spaces. It was important to me that the system be very quiet.
I contacted the manufacturer before my purchase for a recommendation on fan size and type. They recommended this model.
The fans are mounted inside a drop ceiling, connected to dedicated supply and return ducts, and wired to a thermostat. The thermostat is programmed to cycle the fans periodically for air exchange or run them constantly when the temperature downstairs exceeds a set point due to my wood stove operating,
When I first saw them, I was concerned they were too small. However, I found they are very quiet and move a lot of air. I wired them up on the low speed and that is more than enough. The more distance you have between the fan and its supply or return grill the quieter your application will be. I can barely hear them run.

The documentation is paltry, but it's a pretty straight forward device. The two sides come off for mounting, and one side has a baffle in it, which I didn't realize till it was too late. I had to assemble it each way and evaluate which one was more quiet.
It's mounted above a suspended ceiling and is quiet enough to not disturb anyone or even make anyone raise their voice (when wired on the high speed). You can hear a low "whirr" in the background, similar to perhaps a central A/C.

Well built at a good price
Bought this as a blower for a fireplace (blowing into the air space around the box) and it works great; moves a good amount of air pretty quite. I recommend wiring it to either the high or low speeds. Installing a dimmer on it and running it at lower speeds doesn't work so well as it has a low tone humm. I definately recommend the product and this site.

Great retrofit for kitchen hood, slow shipping
My existing hood's fan was really loud (even with a new motor). I replaced it with this remotely-mounted unit. Such a retrofit is, however, interdisciplinary: HVAC, electrical, electronics. It may be beyond many do-it-yourselfers.
This unit is high quality and easy to install. It's made of very heavy duty plastic, yet plastic doesn't weigh so much, which makes installation easier.
It is moderately noisy, but as a remotely mounted unit, it is much quieter for the cook.
I initially expected quick shipping from Chico, CA, just a couple hundred miles away. However, it took forever to arrive. It turns out that when ventingdirect.com got my order, they just called (SLOWLY called) the manufacturer in Florida, and had it drop shipped from there. Why did buy from a California company? I paid California sales tax for something shipped from Florida. Buy this unit from ventingdirect.com only if you are close to Florida, and definitely not if you're in California.

What I expected
I had another 6" mushroom fan for air filtration that was twice as strong, metal, and twice as much cost. I was looking for a fan that wasn't as powerful, loud or as costly and took a shot at this one. I was however concerned with it being "reinforced PVC". As it turns out, while installing it I dropped it and the edge of it chipped about 1/2" of the edge. I repaired and installed it anyway. I found it was very quiet and suited my needs perfectly. I liked that it had 2 speeds, of which I wired it for the stronger of the 2. The CFM worked out to be just right for my needs and it was easy to install. The metal fan I wound up putting a dimmer switch on so I could add some flexibility to it so it would suit my needs.
Yes, I'd recommend this fan to anyone that has to move air quietly and cost effectively. In fact I expect to order another one soon. I called and asked a few questions about the fan before ordering and got help quickly. Shipping was quick as well. It arrived 3 days early!

Purchased this fan for venting near my bedroom so it needed to be quiet - pleased to say this fan is very quiet, only thing you can hear is the sound of the air moving. It also moves a lot of air through static pressure and is much more powerful than the cheap duct booster fan, worth every dime.

The fan is very quiet and powerful
This fan is very quiet and powerful. I am using it with a 4 bathroom common duct into an air to air heat exchanger to heat outside air. Venting Direct had a better price by 10% than the local industrial wholesaler so that is why I bought it from them. Their shipment was very prompt!

I had high expectations for this fan: very quiet and move lots of air. It shattered them. I can't hear it running it is so quiet. Also very simple to install.
I like it so much I just bought another one for our second bathroom.

This fan moves air quietly. It was easy to install and does the job I intended it to. Draws moist air out of my sun room when using my hot tub, room size is 14 x 21. Installed in unheated attic. Hope it lasts!

Blower excellenct but be carefull of controls
Quality product, easy to install but required 6" to 7" vent pipe adapers. Variable speed control caused a hum at low speed and had to change to a 4 step "quiet" control which worked perfectly.
