Aygrochy Quiet 6” Inline Duct Fan with Temperature Humidity Controller - Ventilation Exhaust Fan Using for Heating Cooling Booster, Grow Tents, Hydroponics,Home use Ventilation and Exhaust Blower.

The fan comes with a controller and a plug in temp sensor. Power goes to the fan via the 3 pin plug then the controller can be placed approx 2 mtrs away and the temp sensor another 1.5 mtrs if needed. The fan has 10 speeds and the controller ramps up the speed in steps so keeps the current draw low. The ‘auto’ setting wasn’t quite as automatic as I’d hoped as in it won’t vary the fan speed to suit the temperature set point. Instead you pre-select the desired speed setting and the controller turns the fan on/off according to the temp or humidity set points. You can give it maximum and minimum set points to run the fan within so it’s quite flexible, will take a bit of trial and error playing with the settings but it will make sense (note you have to put a value against each one of the high/low temp and high/low humidity before the controller is ready to take over (those parameters flash at you indicating they need attention) I am not tech savvy but managed it fine. The fan itself is well put together and can be easily split away from the casing and withdrawn without disturbing the ducting either side. Fan is quiet and doesn’t vibrate at all, on speed 10 the air noise is more pronounced.

Bought to replace a broken down system air fan with similar specs but which is now approx 10 years old and has been running continuously since I bought it, we will see if this new one lasts as long. Worked straight out of the box, as described but about half the cost of the system air.

Good

Its OK but noisy comparing to a infinity 6 in and ac infinity has Bluetooth for ext monitoring. I don't think it will last the specified time like ac infinity. Ac infinity runs double bearings and the fan is perfectly balanced. This unit has weights on every blade this creates wind noise and balance noise has a continual whine at anything above 3. But has worked for the months let's see. The similar motor from the same company lasted 6 months. So cheap is not best.

Bought this to help vent a crawl space under the house. Vents really well, item feels like top quality construction and it's doing the job really well. Only downside is that it's not as quiet as expected as can hear it in the room above. But it's not loud enough to disturb, you just know it's running.

Fan is very noisy even with a silencer on it if your looking for a fan with low noise I wouldn’t recommend this fan what so ever item description is not accurate at all

This product is brilliant, value for money at its best. Really powerful motor, the display, sensor and settings work great! I installed this for a client who wanted to duct hot air out of his attic during hot days, with the settings on the screen and triggering options. It worked perfect. Highly recommend this product and will be choosing it again.

The controller seems a bit rubbish. It only wants to display in F which is frustrating. I thought I could set my minimum and maximum temperature settings and it would adjust the speed accordingly to keep it between them. But no. It comes on when above the max temp or below the minimum temp and switches off completely when between them, to me thay seems a bit useless. It also makes more noise than a cheapo swift air xflo even at the lower settings. All in all a bit rubbish for the price and not very useful. Mine will be getting sent back for sure. It does blow air, and seems of a reasonable quality hence the 3 stars instead of 1.

قمت بتجربة المروحة والشفط فيها قوي جداً وفعال. لكن يجب التنبيه أن صوتها عالي بشكل ملحوظ؛ قد يكون السبب هو نوع "الجرجور" المستخدم أو طريقة التركيب التي تزيد من صدى الصوت، لكن وجب ذكر ذلك لمن يبحث عن الهدوء التام. تقييمي لها 4 نجوم بسبب الصوت فقط، أما الأداء فهو 5 نجوم.
